<h4>Change log</h4>
<pre>

<a name=2000.11>
=============================================================================
Changes from mined 2000.10 -> mined 2000.11 (July 2005)
===========================================

Interactive enhancements:
-------------------------
Conciliated keypad assignment preference conflict between Cut/Paste 
functions (as propagated by mined) and character deletion / 
line positioning functions (as often commonly expected):
- Additional character deletion function Alt-Del.
- Better documentation for alternative -k option.
- Changed error message "Mark not set" to include a hint on keyboard usage:
"Mark not set for Cut and Paste - type Alt-Del to delete char, F1 k for help".

Enabled scrolling for popup menus (esp. flag menus) so that menu 
opening in low-height terminals (e.g. 24 lines or lower) is no longer 
suppressed and esp. the Encoding and Input Method menus are always shown.

Updated to Unicode 4.1.0:
* Case conversion, Script information.
* Combining character width properties (continuing to work with older 
  width data versions by terminal auto-detection).
* Updated Han information (from Unihan database) for CJK characters.
* Updated Radical/Stroke input method to include new CJK characters.
* Added Hanyu Pinlu and Tang pronunciation information (from Unihan 
  database) to Han information options.
* Added generic and supplemental character input mnemonics for new 
  LATIN characters.

Indication of Unicode combining characters (visible indication and 
character information) now refers to the most recent Unicode version, 
not the actual terminal capabilities; a combining character not handled 
as such by the terminal will be highlighted also in combined display mode.

Renamed File menu item "Paste file" to "Insert file" (which is probably 
more common usage). So also the menu item "Print" can now be selected 
with a single "p" key.

Additional assignment of "Delete single" function (to delete without 
auto-undent, or to delete the last combining accent only) to F5 Backarrow 
in case Control-Backarrow is not configured.

Renamed File menu entry "New Name" to "Save To ..." which is considered 
more intuitive. It changes the file name associated with the edit 
buffer but doesn't save the file yet; the originally loaded file (if 
any) is not affected.

Additional commands F1 F1 / Shift-F1 / Control-F1 / Alt-F1 to display 
a help line (in the bottom status line) with short indications of the 
functions assigned to the function keys F2... in normal and shifted 
modes. With HOP, permanent display of this help information is toggled.


Interoperability enhancements:
------------------------------
Accepting xterm resource mode "XTerm*modifyCursorKeys: 3".

Accepting Alt-function key combinations from terminals that implement 
them by prefixing ESC.
New option -A to disable this feature and avoid the accompanying delay 
after ESC ESC before mined exits.

Accepting Alt-function key combinations formed by appending ;11 etc 
instead of ;3 etc after ESC [ or by inserting 11 etc after ESC O.

Detecting right keypad function key combinations as distinguished from 
small keypad in rxvt in order to better support the various shifted 
Home/End/Delete key combinations (in support of revision mentioned 
under "Interactive enhancements").

In KDE "konsole" terminal, disabling rounded menu borders by default 
as konsole is lacking decent font support for Unicode characters.
(Patch included in SuSE 9.3 mined 2000.10 package.)

Added keyboard configuration examples for Control-function key detection 
for rxvt and mlterm to the runtime support library.

Replaced function key mappings for "HP workstation keyboard" with 
those for older extended VT100, older xterm, and some others for an 
enhanced range of terminal interoperability.

Added shifted (Control-/Alt-) function key detection for HP terminals 
or (with xterm) keyboard mode.

Added function key detection for SCO terminals or (with xterm) keyboard mode, 
including Shift-/Control-/Alt- combinations, plus PuTTY SCO mode shifted keys.

Added script to support Unicode X font installation to the 
runtime support library.

Added xterm parameter -mk_width to xterm start script "uterm" for 
UTF-8 mode in addition to -u8 (applied from xterm version 201).
This enables the xterm built-in most recent version of Unicode width 
data, even if the system-provided locales maintain an older version.

Provided makefile for Interix. Included function key assignments 
(escape sequences) for Interix console.

DOS version (djgpp): Unified keypad and function key assignments to 
mined functions with general (Unix) version. Remapped specific 
screen size and mode control functions to Control-/Alt- with +, -, / 
(Control or Alt with +, -, or / keypad key).


Further enhancements:
---------------------
New TAB expansion option (-+4 or -+8) that expands TAB key input 
to an appropriate number of Space characters.

Added "smart arrows" input text replacements (in addition to smart dashes) 
if smart quotes mode is active.

Revised print script (uprint in the runtime support library) to use 
paps (a Pango printing script) if available. Removing temporary file 
after printing.

The "search corresponding bracket" commands ESC ( or ESC ) now also match 
/* */ pairs and #if #else/#elsif #endif structures.

Smart text replacements (esp. smart dashes) are suppressed while 
entering multiple characters during a repeat command.

New case toggle function Shift-F3 cycles casing of a word between 
all small, beginning capital, and all capitals. For Japanese script, 
it toggles the word between Hiragana and Katakana.

New function key assignments:
* Alt-F2 to Save to a different file ("Save As")
  (was Control-F2 previously)
* Control-(Shift-)F2 to enforce creation of the text position memory 
  file @mined.mar to ("Save Position", then Save)
* Control-F3 to View a file (edit read-only)
* Alt-F7 / Alt-F8 to search backward
* Control-F10 to open first flag menu (Info menu)

Added PC DOS encoding ("codepage 437") to available encodings.

The command ESC _ (or Control-F11) also replaces an HTML character 
tag (e.g. &euro;) with its represented character.


Packaging, building and installation:
-------------------------------------
Moved doc/compilation to COMPILE.DOC so the subdirectory doc of the 
distribution archive now contains only user documentation.

Added PACKAGE.DOC with hints how to make system-specific mined packages.

Leaving out the default link src/makefile from the distribution as it 
used to confuse some installers for which the default (GNU make and cc) 
does not work. A generic make with auto-detection of the suitable makefile 
should be invoked from the top-level distribution directory as described 
in the file INSTALL.DOC.


Bug fixes:
----------
Fixed missing use of terminal capability to "enable alternate 
character set" (terminfo enacs, termcap eA) so graphic menu borders 
should now work in some remaining cases and no longer be replaced with 
letters.
(Patch included in SuSE 9.3 mined 2000.10 package.)

Fixed partial scrollbar update logic to prevent gaps in scrollbar display.
(Patch included in SuSE 9.3 mined 2000.10 package.)

Tweaked panic handling to terminate more smoothly after a screen output 
error (e.g. if output crashes with ncursesw 5.4 on a more than 3 bytes 
UTF-8 sequence).
(Patch included in SuSE 9.3 mined 2000.10 package.)

Suppressed activation of xterm "mouse hilite tracking" mode if compiled 
with curses.
(Patch included in SuSE 9.3 mined 2000.10 package.)

Fixed menu border handling with xterm -cjk_width mode, including a 
workaround for xterm font handling bug.

Emacs command mode (-e): Fixed ^X^C not to unconditionally save file 
but to prompt first (like mined command ESC q).
Also fixed ^Xk (which previously behaved like ESC q) to edit a new 
file (thus discarding the edit buffer, like F3).

Fixed part of keymap generation mkkbmap (yudit keymap auxiliary script).

Fixed character width interworking problem with CJK-encoded rxvt.

Fixed missing display of menu continuation indication (scrollable 
keyboard mapping pick list) with non-graphic menu borders (option -Qa).

Fixed recognition of smart quotes style in previous file editing session.

Limited display of pull-down menus (File menu etc., not flag menus) to 
screen height so that in low-height terminals (less than 22 lines) 
confusing bottom menu item display is avoided when navigating down.

Fixed incorrect usage of terminal height adjustment (workaround for 
occasional cygwin xterm mismatching xterm / tty size, since 2000.10) 
for window height lower than 24 lines.

Added error detection and message to command "Save Position" but not 
to implicit save position function when actually writing the file 
as the message would inappropriately interfere with the file writing 
information (and maybe error message referring to this).

Fixed re-positioning to previous cursor position after opening a file 
when the previous position had been after a combining character.

Fixed wrong sorting sequence of non-BMP case conversion entries 
leading to case toggle not working for various (also BMP) characters 
(since 2000.4).

Unified function key assignments of some special keyboards with those 
on usual keyboards (xterm, VT100, ...):
F6, F7 on Sun and HP keyboards, F10, F11, F12 on Iris keyboards, 
F16-F20 on 9780* keyboards.
Mapped F13-F22 on 9780* keyboards generically to Control-F3-F12 (may 
be shifted in addition).

Fixed display of control characters on prompt line in CJK mode; (they 
were incorrectly echoed, and incorrectly handled when erased, in 2000.10).

Explicit encoding option (-u, -EG, -EW etc) has to override environment 
preference for text encoding (unless for non-CJK encoding in CJK terminal 
which is not supported). Fixed missing overriding.

Removed remark in manual page (option -E with CJK encoding) that 
UTF-8 auto-detection could override explicit encoding selection which 
is not true anymore since 2000.10.

Fixed writing of panic file on nested catching of external signals.

Fixed missing update of window title (file name) in some cases when 
file name was changed for writing but writing was cancelled.

Fixed selection of usable temporary directory with respect to 
considering its write permissions.

Fixed flickering multiple update of flags area when starting mined 
(e.g. showing "L1" twice, then "U8") (since 2000.5).

Fixed smart quotes mode handling to be taken from previous editing 
session when opening a file which did not properly set 
plain style in some cases (since 2000.9).


<a name=2000.10>
=============================================================================
Changes from mined 2000.9 -> mined 2000.10 (February 2005)
==========================================

Features:
---------
Added radical/stroke lookup input method for CJK characters.

Added Han character information (Han info option in new Info menu) for 
both text browsing and pick list character selection. This displays 
selectable character pronunciations and descriptions from the Unihan 
database, either on the status line or in a popup menu.

Poor man's bidi mode was tweaked and enabled by default unless the 
terminal is detected (or configured) to be a bidi terminal; this mode 
enhances inserting small pieces of right-to-left (e.g. as quotations) 
into left-to-right text; when switching from right-to-left back to 
left-to-right by entering a left-to-right character, the cursor 
automatically skips to the end (visual end) of the previously entered 
right-to-left text on the line. This priority is justified by the 
assumption that this mode (with visual storing order) is only useful 
for inserting small right-to-left quotations into left-to-right text 
and not for editing right-to-left documents (which should be stored in 
logical order).

Many more enhancements and additions for internationalisation and 
character encoding support:
* Updated character data to Unicode 4.0.1.
* Combining characters in CJK encodings are now supported.
* Multiple mapped 8-bit character encodings are available, including 
  full combining character support.
* UTF-16 is handled transparently.
* For details and further features see below.

Many enhancements and additions for character input support:
* CJK, Vietnamese, Thai, Hebrew.
* Combined character editing in CJK and 8 bit encodings.
* For details and further features see below.

New header line command HOP "-" underlines the line that starts before 
the cursor position.

Added a printing feature that prints the text being edited 
considering the selected text encoding. (It uses a Unicode printing 
script contained in the runtime support library and the uniprint 
program from the yudit package.)
Modified the item in the File menu to print the file (or actually 
the edit buffer), not the paste buffer.

The menu interface was enhanced, see below.


User interface enhancements:
----------------------------
Enhanced menus with subtitles.
Enhanced flag menus with markers that show which options are activated.

Made menu items selectable by typing the first letter of their 
descriptions, cycling through all items beginning with that letter.

Enabled menu item selection by mouse wheel scrolling. Note that your 
mouse driver may be configured to generate multiple (e.g. 3) mouse 
wheel events on one mouse wheel movement (e.g. with Windows).

Rearranged default input method menu according to the order of the 
letters "CJK".

Keyboard mapping selection menus ("pick list") that are too large to 
fit on the screen are now scrollable and pageable (with cursor keys).

Revised navigation in pick lists (keyboard mapping selection menus); 
improved highlighting and function of cursor movement.

New mode for more stylish menu item selection highlighting (-QQ). 
Looks nice on Unicode terminals. Not made the default, however, 
because block characters used for it might not align well with simple 
borders with all fonts.

Displaying line-end entered on prompt line (esp. for searching) using 
highlighted marker representation (like for text display) rather than 
control character representation.

Revised character indications for characters (esp. CJK) that cannot 
be displayed for various reasons; made indications uniform on 
different terminals.


Command interface enhancements:
-------------------------------
^V followed by a function key now generically invokes the same function 
as with control-function key.

Enhanced numeric character input with the option of Unicode value 
input in CJK or mapped 8 bit mode by typing a 'u', 'U', or '+' (in 
addition to an optional '#' or '=' for octal or decimal numeric input).

With numeric character input, the Space key was modified to enable 
"successive multiple character entry" according to ISO 14755; so if 
the numeric code is terminated by a Space key, another numeric 
character can be entered subsequently.

Added Alt-E command to open encoding menu; modified Alt-V command 
to toggle between view only and edit mode (to reuse previous Alt-E).

Added Alt-F10 to open first flag menu (info menu).

Added cedilla accent prefix function to ctrl-F5 (combining this and 
ring above as they are not ambiguous).

Added Help to eXtra menu.

Additional command ESC @ to set marker (in addition to control-@ / 
control-Space, ESC ^, control-], or the Home or Select key, for the 
sake of keyboard configurations that cannot easily enter those - 
control-Space may not be configured, ^ may be an accent prefix "dead key", 
control-] may be caught by telnet, Home may be cumbersome on Laptops).

The "search corresponding bracket" commands ESC ( etc. were extended: 
In case you are editing a mailbox file, these commands also work for 
MIME separators or mail headers; in this case, the search direction 
depends on the command character, e.g. ESC ( searches backward, ESC ) 
searches forward.

Added command Alt-F9 to repeat the previous search but in the opposite 
direction. Added command Alt-Shift-F9 to search for current identifier 
backward.


Mnemonic input support enhancements:
------------------------------------
Completed mnemonic patterns (generic accent mnemonics) for Latin-based 
characters, supplemented more intuitive patterns for "accents below".
Completed documentation of these mnemonic patterns and enhanced the 
overview in the manual and on the "Character Mnemos" web page.

Revised additional character composition mnemonics; made additions 
consistent with generic RFC1345 mnemonics, removed redundant mnemonics, 
added missing Latin characters (esp. with multiple accents).

Tweaked mnemonic character input handling to allow input of ambiguous 
mnemonics in long mnemonic input mode (e.g. "^V pi " in contrast to 
"^Vpi", where the long form prefers the RFC 1345 mnemonic).
The ugly previous solution to prepend an additional "1" for ambiguous 
RFC 1345 mnemonics was replaced by this new mechanism.

Enabled mnemonic character input support (^V Space mnemo Return) 
for non-UTF-8 encodings.


Input method support enhancements:
----------------------------------
Added two input methods to the default set of preinstalled input methods:
WuBi (after having read it's perhaps the fastest input method used by 
professional typists in mainland China) and 4 Corner.

Added generation feature for further keyboard mapping tables 
(used as input methods) for further mappings from Unihan data 
in addition to Cangjie: MainlandTelegraph and TaiwanTelegraph codes, 
pronuncations for Cantonese, HanyuPinlu, Mandarin, Tang, 
JapaneseKun, JapaneseOn, Korean, Vietnamese.
(Not included in distribution as these seem of questionable value, 
entries included in keymaps.cfg but disabled.)

Added generation feature for further keyboard mapping tables 
used for Vietnamese input methods: VIQR , VNI , Vtelex.
Include VIQR and VNI in the default configuration.

The keyboard mapping generation script mkkbmap inserts additional 
punctuation automatically.

With the environment variable MINEDKEYMAP, both active and standby 
keyboard mappings can be preselected, e.g. MINEDKEYMAP=py-rs.

Option +K enables keyboard mappings (input methods) even in 8-bit 
terminal or when editing a Latin-1 file - although the characters thus 
entered will mostly only be displayed by substitute indications, as 
most characters anyway when editing UTF-8, CJK encoded, or mapped 
8 bit encoding files in an 8-bit terminal.

Keyboard mapping generation from Unihan data (with mkkbmap using mkkmuhan) 
sorts characters in entries according to the priorities of their 
Unicode ranges (assigning lower priority to "Supplement" and 
"Extension" and "Compatibility" ranges).
This especially affects the Cangjie input method in a few character 
selections. So the "pick lists" are now displayed more in order 
of relevance.


Further input support enhancements:
-----------------------------------
Added Vietnamese accent prefixing method found on the web, using 
control/alt-digit combinations as prefixes. This is only enabled 
when additional key translations for xterm are configured with 
the X resources. (Added to Xdefaults.mined sample file.)

Added character composition mnemonics (using generic accent prefixes) 
for Vietnamese double-composed characters, i.e. placing a second accent 
on Vietnamese base characters that already have a single composition, 
e.g. if you have mapped your keyboard to have A with circumflex 
available, you can enter "^VÂ'" (Control-V A-circumflex apostrophe) to 
produce the combined character U+1EA4 (A with circumflex and acute).

Added a Thai input method.

Added control-backspace function that removes combining accents from 
combined characters and also does not unindent on leading blanks.
This is only enabled when an additional key translation for xterm is 
configured with the X resources. (Added to Xdefaults.mined sample file.)

Added Hebrew quote style (using Gershayim U+05F4 for quotation 
and Geresh U+05F3 for apostrophe), and added Hebrew Maqaf (U+05BE) 
as a smart dash replacement for "-" if there is an adjacent Hebrew 
character.


Character encoding support enhancements:
----------------------------------------
Updated character data to Unicode 4.0.1:
case conversion, character-to-script mapping, screen width (continuing 
to work with older width data versions by terminal auto-detection).
Updated keyboard mapping table for Cangjie input method accordingly.

Combining characters in CJK encodings are now supported 
(both JIS encodings and GB18030), in either UTF-8 or CJK terminal mode.

Added further 8-bit character encodings, including full combining 
character support.

Maintaining UTF-16 transparently, i.e. a UTF-16 encoded file is 
written back in UTF-16 again (with BOM) (was previously converted 
to UTF-8). No explicit menu/command line options are currently 
available for UTF-16 as internal handling is in UTF-8.

Made handling of Unicode LS and PS line ends (previous option -uu) 
the default. New option +u-u disables them.

The character information command (ESC u) or mode (HOP ESC u) was 
enhanced to conform to ISO 14755; in UTF-8 mode, CJK mode, and 
mapped 8 bit encoding mode, Unicode character information is displayed 
additionally: script name, character category, and Unicode value.

The Han character information mode always shows the character code, 
and in CJK encoding mode additionally the Unicode value, independently 
of availability of Unihan character descriptive information for the 
current character.

Added options +C, +CC, +CCC for fine-tuning of display of unknown 
CJK character codes on CJK terminals.

Added option -CC to assume CJK terminal and override UTF terminal 
auto-detection.

Revised (fixed/tweaked) character value transformation commands 
[HOP] ESC X/U/D/A to perform a more useful and consistent set of 
functions; HOP ESC X now also scans a UTF-8 sequence; [HOP] ESC U 
now transforms values between current text encoding and Unicode; 
[HOP] ESC D/A now acts like [HOP] ESC U but using decimal/octal.


Interoperability enhancements:
------------------------------
Improved UTF-8 and CJK terminal feature auto-detection for speed-up on 
slow terminal connections.

Assuming terminal to run PC character set (codepage 437) if 
environment variable TERM begins with "pcansi", "nansi", "ansi.", 
or contains "-emx", to support remote login from DOS box to Unix.

Enabled optional PC character set operation when running cygwin version 
in DOS box (when using CYGWIN=codepage:oem in a DOS box).

Added handling for rxvt-specific cursor and function key escape sequences.

Revised handling of screen attributes for better and extended support 
of legacy terminals, relying more on termcap and checking if 
direct use of ANSI controls as a fallback is appropriate (usage 
of hard-coded ANSI controls cannot be just avoided because for many 
colour terminals, colour handling is usually not configured with 
termcap/terminfo but of course users want the xterm colour feature to 
be made use of).

Enabled semi-stand-alone operation of cygwin version (with only 
cygwin1.dll needed to be available, but without installed cygwin 
system, especially without termcap information accessible) by assuming 
hard-coded terminal properties for the "cygwin" terminal if it is 
unknown by the system.

Enabled menu border option -Qa for DOS version for use with embedded 
dosemu (esp. running in an xterm where it does not emulate DOS block 
graphics characters).

Enabled menu border option -Qa for curses version, and enabled use 
of Unicode menu borders for curses version.

Tweaked terminal block graphics capability detection, enabling block 
graphics (rather than ASCII graphics) on more terminals (e.g. cygwin).
Also using termcap "ac" / terminfo "acsc" capability now to support 
proper block graphics on more terminals (e.g. mac, ibm3151).

Abolished use of the MINEDTERM variable. Now determining all 
terminal-specific properties and restrictions from TERM.

Added make target "minced" to build a curses version; it uses 
the ncursesw library which supports UTF-8. Using curses is discouraged, 
however; see the comments in doc/compilation.


Building and installation enhancements:
---------------------------------------
Added installation of runtime support library (online help, templates 
for inclusion of environment settings and X resources, scripts to 
configure and invoke xterm in a suitable way, printing script, script 
that helps building a printing environment).

Added make targets "localinstall", "optinstall", and "homeinstall" so 
the user can choose explicitly to install in /opt or $HOME/opt, or in 
either /usr or /usr/local with corresponding different subdirectories 
as used by various systems.

Revised makefiles to improve building on legacy systems.
For dynamic make targets / dependencies, introduced dynamic makefile 
generation with non-GNU make. (Maintaining two versions and keeping 
$(shell ) feature with GNU make for less confusing user feedback.)

Revised directory names used in makefiles for installation of 
mined manual and help files as used by various systems in the 
/usr or /usr/local hierarchies.


Further enhancements:
---------------------
Added push marker stack before searching for current character (HOP ctrl-F8).

Improved documentation how to set up a common inter-window paste 
buffer in a heterogeneous network using the environment variables 
$MINEDTMP and $MINEDUSER. Enabled using the same buffer for 
DOS version (djgpp).

Added environment variables ESCDELAY and MAPDELAY to tune the waiting 
time applied for recognising function keys or input method sequences to 
be mapped, respectively.
ESCDELAY also affects the time the terminal has to respond to a 
cursor position report request (used for terminal capability detection).

Added push to marker stack before replace with confirm (ESC r) starts.

Added command line option ++ to terminate options (to support 
filenames that start with "-" or "+").

Revised checking and reporting attempts to enter, compose or transform 
character codes or mnemonics that are illegal or not valid in the 
current encoding; e.g. added "Invalid character" feedback when trying 
to insert a character that does not exist in the current encoding.

Added "o" to the set of numbering items taken into account with 
clever paragraph rewrapping.

Special handling of Turkish "i" for case toggling is now triggered 
by environment variables LANG or LC_ALL or LC_CTYPE beginning with "tr" 
(rather than the special variable MINEDTURKISH).


Bug fixes:
----------
Fixed cursor remaining invisible after using a menu in cygwin version.

Fixed makefile to enable compilation with djgpp again.
This also fixes a compilation problem with some SunOS configurations.

Fixed mnemonic character input handling to enable input of ambiguous 
HTML mnemonics starting them with "&" (e.g. "^V &not ", broken since 
mined 2000.8).

Changed separated display mode indication flag from acute to grave to 
avoid interference with ambiguous width property (xterm option 
-cjk_width). Also its background colour was changed from reverse to 
cyan to be consistent with the combining character display itself.

Disabling fine-grained scrollbar if -cjk_width terminal mode is 
detected to avoid interference with ambiguous width property.

Constrained usage of "mouse hilite tracking" mode to xterm; 
on some other terminals (esp. cygwin, rxvt) this could interfere with 
a scroll down control sequence and would incorrectly scroll down the 
screen on left mouse clicks (since mined 2000.4).

Tweaked mkchrtab script (compiling character set mapping tables) to 
work for cygwin in some cases that used to expose weird compiler errors.

Fixed positioning problem after suppressing second quote mark in 
flags area if first quote mark is a double-width character (used 
to output a NUL character then which produces a space on some terminals, 
e.g. cygwin DOS box - this is now being suppressed).

Considered to constrain usage of 256 colour mode to "xterm" to avoid 
screen garbage if the mode is not compiled in to rxvt and other 
terminals.
This applies to scrollbar colours (unless explicitly configured with 
environment variables) and to Unicode script highlighting (by 
lowest-distance mapping of colours to the 8 basic colours).
(But as screen garbage with buggy rxvt occurs only in some 
configuration modes, 256 colour usage was left enabled there.)

Fixed GB18030 auto-detection and width handling.

Fixed EUC-JP half-width character width handling in CJK terminal 
(rxvt in EUC-JP mode). Note that these characters are not displayed 
properly by cxterm in EUC-JP mode.

Fixed overriding of explicitly selected CJK encoding (e.g. -EG) by 
VISCII auto-detection (since 2000.9).

Avoid using vt100 graphics for menu borders in rxvt and cygwin xterm which 
do not seem to support them (option -Qv is available to enforce them).

CJK character codes that do not map to Unicode are now displayed 
with the indication '?' with cyan background to avoid screen garbage by 
invalid character codes, unless overridden by the +C option for 
transparent display of CJK encoded characters.

Fixed buffer size limitation for search expression ranges not to 
corrupt buffer.

Fixed interrupted highlighting in selected line of quote style menu in 
8 bit terminals after non-8-bit quote mark replacement indication.

Fixed error messages on character input support (e.g. mnemonic) to 
be consistent with respect to "Unknown character mnemonic" versus 
"Invalid character".

Enabled input of NUL character with ^V NUL (^V control-Space).

Fixed fine scrollbar display which used to mix up top and bottom part 
of marker in some cases.

Fixed fine scrollbar display which used to leave gaps in some cases of 
adding lines.

Fixed resolving ambiguous function key control codes with certain 
specific terminals.

Fixed margin interpretation when setting left or right line margins to 
current position with Enter in a shifted line - using real line column 
now instead of screen column.

Fixed missing refresh of menu header line after cancelling a keyboard 
mapping pick list by clicking on the encoding or combined display flag.

Fixed incorrect assumption of combining screen if locale was incorrectly 
configured to indicate UTF-8 in a non-UTF-8 terminal.

Fixed reverse highlighting problem on some terminals with mnemonic 
character input on prompt line.

Enabled scrollbar display in djgpp version.

Fixed function key detection for DOS versions compiled with curses 
which was broken since 2000.7.

Disabling pipe input/output detection in DOS version when DOSBox is 
detected (by looking at %COMSPEC%).

Fixed display bug after inserting TAB in CJK-encoded text.

Fixed inappropriate "conversion" of line-end into U+3000 with 
diacritic transformation command (ESC _) (since 2000.8).

Workaround to accept delayed cursor position reports instead of 
giving an error message. This affects slow remote connections and 
the cygwin terminal if configured with CYGWIN=tty (in which case the 
cursor report comes only after the first keyboard input which is a 
cygwin bug).

Fixed generation of script colouring table from colours.cfg which 
could have failed with small-letter script names depending on locale 
environment (since mined 2000.10 alpha as script names were all-caps 
before).

Fixed ^V__ which didn't input ^_ as documented (since mined 2000.4).

Tweaked scrollbar attribute handling so that useful scrollbar display 
is enabled in hanterm. This needed a workaround so that the scrollbar 
position is now indicated by blank space in a CJK terminal using 
Korean encoding (UHC or Johab) if TERM=xterm. If you use another 
terminal in this configuration (e.g. cxterm or rxvt with TERM=xterm) 
set the environment variable MINEDSCROLLFG="44;36" or ="38;5;45" 
to reenable coloured display of the scrollbar position.

Fixed display bug when an incomplete UTF-8 sequence was followed by 
a TAB character.

Fixed non-ASCII command characters to work regardless of active 
encoding.

Fixed missing indication for no-break space (U+A0) in UTF-8 mode 
with djgpp-compiled version (was inconsistently shown as blank).

Fixed one buggy entry in VISCII character mapping.

Added ASCII remapping entries in Shift-JIS and Johab character mappings, 
and handling them for display and input.

Tweaked encoding toggle function (when clicking on the character 
encoding flag in the flags area) to properly toggle between the 
current and the previous text encoding.

Fixed xterm workaround of tweaking window title string (showing the 
filename) for non-ASCII characters in UTF-8 screen mode.

Fixed Turkish case conversion special handling which was broken since 
2000.4; added further special handling for Turkish and for Lithuanian 
COMBINING DOT ABOVE.


<a name=2000.9>
=============================================================================
Changes from mined 2000.8 -> mined 2000.9 (March 2004)
=========================================

Enhancements in character encoding handling and input support:
--------------------------------------------------------------
Used more compact representation for character set tables and 
keyboard mapping (input method) tables, reducing size of binary by > 700K.

For Japanese encoded text on a UTF-8 terminal, the JIS encodings that 
map to two Unicode characters are supported.

Keyboard mapping / input methods: Configurable function of space key 
in multiple choice selection menu (option -K).

Keyboard mapping / input methods: added support for VIM keyboard mapping 
files.

Tuned CJK encoding auto-detection.
Tuned CJK vs. ISO 8-bit auto-detection.

Added VISCII auto-detection.

Added Shift-JIS auto-detection.

CJK encodings may be selected (or disabled) to be taken into account 
for auto-detection by configuring the environment variable MINEDDETECT.

Added option -l for more intuitive selection of Latin-1 text encoding 
(and disabling of auto-detection) rather than with +u.

Tuned terminal mode auto-detection to reduce flickering delay on 8-bit 
xterm (using fewer test strings) and improve stable fallback if 
auto-detection fails partially on slow terminal connections.

The keyboard mapping menu can be grouped with separators, specified 
in the keymaps.cfg file.


Features:
---------
Smart quotes: auto-detection of quotation marks style on file loading.

Keyboard mapping / input methods: added support for VIM keyboard mapping 
files.

New functions for interactive character encoding conversion 
(Latin-1 / UTF-8) to partially fix files with mixed encoding:
A search function finds UTF-8 characters in Latin-1 mode, and vice versa.
The character can then be converted into the current encoding.
The search function is invoked with HOP search corresponding - 
e.g. HOP ESC ( - or Alt-F11 .
The conversion is invoked with the diacritic transformation function, 
e.g. ESC _ or ESC ö , which was extended for this purpose.
For repeated interactive conversion, both functions can be combined 
with Alt-Shift-F11 (convert current character, then search next).


Enhancements in user interaction:
---------------------------------
Implemented a finer-grained scrollbar in a UTF-8 terminal, using 
Unicode character cell vertical eighth blocks U+2581..U+2587.
(Can be disabled with -o1 if font does not contain those characters.)

Implemented lazy scrollbar update for speed-up on slower 
terminal lines (e.g. remote access). (Can be disabled with -o8.)

Verified correct recognition and function of mouse wheel movement. 
Scrolling by multiple lines (option -LN, default N=3), or by 1 line 
with control, or by 1 page with shift.

Added "paste previous" function (emacs style buffer ring) to Edit menu.

Added backspace capability to decimal number input function (e.g. to 
enter a line number or margin column).

Tuned position of popup menu not to appear far right of the line contents; 
if clicked there, the menu is placed on the the line end 
(which is the new cursor position in this case).

The diacritic transformation command (ESC _) derives language-specific 
preferences (such as can be explicitly applied by using the command 
variations ESC ö etc) from the locale environment.

Added a sample xterm key translation to Xdefaults.mined to assign 
the HOP function to the Scroll Lock and Pause keys in order to 
provide the HOP function easily on Laptops/Notebooks.

Making cursor invisible while menu is open.

Revised menu names for CJK encodings for better recognition.


Further enhancements:
---------------------
Position stack and return function also work across files 
(esp. after identifier definition searches using tags file).

Added /usr/share/info as a search path location for the online help file 
to meet cygwin conventions, adapted makefile.cygwin installation dirs.

When editing multiple files, switching to another one resets the 
view only flag to its invocation state (option -v).

Tuned various file loading functions (including character encoding 
auto-detection) to speed up startup with large files.


Bug fixes:
----------
Fixed declaration of getenv which caused failure on 64 bit systems.

Added quotes to egrep parameter in global makefile, needed with some 
shells (would cause make to fail on SunOS).

Fixed display of non-break space (0xA0) in Latin-1 text and terminal 
mode on prompt line.

Fixed missing tolerance against multiple blanks separating choices 
in keyboard mapping files.

Fixed encoding handling problem after toggling from VISCII to UTF-8 
(by clicking on encoding flag).

Fixed width assumption when inserting certain characters (e.g. Euro sign) 
in GB18030 mode which led to wrong cursor position.

Fixed a problem with moving between flag menus.

Fixed a missing screen update problem after replacements with 
embedded newlines.

Fixed a wrong screen update problem (missing lines near end-of-file 
on screen) after replacements with embedded newlines.

Fixed corrupted paste buffer after tags file search (for identifier 
definition, ESC t) that spoiled a subsequent paste operation with 
inserted garbage.

Added auto-detection of terminal capabilities for plane 2 double-width 
and plane 1 / plane 14 combining characters, avoiding display confusion.

Fixed cursor positioning problem when mouse was clicked during prompt 
line input after menu invocation.

Fixed cursor positioning bug (since version 2000.8) after character 
insertion on the first screen column in a shifted line (an overlong 
line shifted for display).

Fixed paragraph justification (line wrap) to use TAB for indentation 
on subsequent lines (instead of blanks) if a numbered paragraph starts 
with a TAB after the numbering (as it used to do with unnumbered 
paragraphs).

Restricted mode (--) prevents ESC E (switch from view only to edit mode) 
and ESC W (save unconditionally).

Re-included Turbo-C 2 project file which had been overwritten by 
Turbo-C 3 project file. (Turbo-C is not really recommended anymore 
but as it still compiles, I'm keeping it available.)

Adapted format of online help files to avoid multiple backspace 
characters for bold formatting which does not work with newer 
versions of less.

If the editing buffer cannot be filled (out of memory), the associated 
file name is cleared to assure that the file is not accidentally 
overwritten with its truncated buffer version. (This was already 
unlikely because the editing mode was set to View only, but it could 
still be saved with an enforced Save command like Shift-F2 or ESC W.)

Not displaying the number of characters anymore after loading a file 
with CJK encoding and without predetermined encoding (e.g. loading with 
-C only, or just by auto-detection) because the number used to be wrong.
The correct character count can be displayed at any time with the ESC ? 
command. Character count after loading is still displayed for Latin-1 
or UTF-8 encoding, or if CJK encoding was explicitly specified (e.g. -EG).

Fixed bugs in ESC t command (to find declaration of current identifier) 
if tags file search expression contained special characters (tab, \, *).

Fixed top of marker stack not being recognised as such after marker 
push operations.


<a name=2000.8>
=============================================================================
Changes from mined 2000.7 -> mined 2000.8 (August 2003)
=========================================

Features:
---------
Major extension of CJK character set support: GB18030 
(Unicode-compatible 4-byte extension of GBK), 
extended EUC-JP (including 3-byte encodings), 
and CNS (EUC-TW with 4-byte encodings).

Added support for mapped single-byte character encodings, 
enabled Vietnamese VISCII character set (option -EV).

Auto-detection of terminal features (UTF-8, different width data 
versions, handling of double-width, combining and joining characters; 
CJK, handling of non-EUC code points, GB18030, 3-byte and 4-byte encodings).

Flexible locale configuration for both text and terminal encoding:
Mined accepts both explicit encoding suffixes (starting with ".") or, 
if none are specified, also some region suffixes (starting with "_").
See manual page, section "Locale configuration".

Smart dashes: If smart quotes are active, also an input sequence 
of "--" is replaced with an en dash (if preceded by a blank) or 
an em dash.

New emacs mode: functions are assigned to control keys and Meta-keys 
(ESC commands) as defined by the emacs editor. Also the emacs paste 
buffer ring and cut/paste behaviour was implemented.
This mode is in beta state and detailed documentation (esp. command 
listing) is not available yet.
The mined ESC commands can be reached via Meta-x.
Function keys remain unaffected.
See also option +V.

The multiple buffers ring is also available in non-emacs mode.


Enhancements in special display of character encoding:
------------------------------------------------------
Enabled display of Unicode FULLWIDTH forms in Latin-1 terminal.

Enabled substitute display of CJK encodings in Latin-1 terminal, 
with clear display of FULLWIDTH ASCII.

Enabled substitute display of Euro sign in Latin-1 terminal.

Alternative options -Eg / -Ej / -Ec to set -EG / -EJ / -EC but 
if running in a CJK terminal this tells mined to assume that the 
terminal cannot display GB18030 4-byte encodings, CNS 4-byte 
encodings, EUC-JP 3-byte encodings, respectively.

Revision and improvement of CJK display indications:
¤  (cyan background) (8-bit terminal): CJK cannot be displayed here
@  (cyan background) (CJK terminal): CJK code cannot be displayed on terminal
# (cyan background): invalid CJK code (not assigned in selected encoding)
# (cyan): illegal (esp. incomplete) CJK code

The character encoding indication in the flags area was extended to 
two letters.


Enhancements in character input support:
----------------------------------------
Tweaked handling of character selection menu ("pick list" for 
multiple choice mappings) so that a blank key moves on to the next 
alternative. Also the cursor-right/left keys move within a selection 
line now.

Added input method TUT.roma for Japanese.
Revised Hiragana and Katakana input method tables.

CJK input method tables were extended with punctuation mappings.

Extended low/capital letter toggle function (F11) to toggle 
between Hiragana and Katakana.

Enhanced smart quotes heuristics to support smart quotes in CJK text.

Revised input mnemonics for Unicode accented characters; removed 
redundant mnemonics.

Additional input mnemonics :(, :), ): for smileys (Unicode mode).

Diacritic transformation function enhanced with language-specific 
preference transformations:
control-F11 and ESC _ apply the default transformations 
which are the same as available for two-letter mnemonic input (e.g. ^Vae).
With Escape commands with diacritic letters that occur on respective 
national keyboards, the according preference transformations take 
precedence:
ESC ö, ESC ä, ESC ü, ESC ß: ae->ä, oe->ö
ESC é, ESC è, ESC à, ESC ù, ESC ç: oe->oe ligature (Unicode mode, U+0153)
ESC æ, ESC å, ESC ø: ae->æ, oe->ø
ESC _, control-F11: ae->æ, oe->oe ligature (Unicode mode, U+0153)


Enhancements in command input:
------------------------------
Made Delete/Remove keys on keypads configurable to either Cut or 
Delete character right. The option -k now switches all Home/End 
and Del keys to the more usual behaviour, although I still think 
it's a waste of keypad space to have these functions on two 
keypads; I think the mined approach to leave the standard behaviour 
on the "small keypad" and assign buffer functions to the right-most 
keypad is more useful.
If the keyboard emits specific control and shift sequences, 
control-Del is always "Delete character right" and shift-Del is 
always "Cut to buffer" in either key assignment mode.
Also control-Home and control-End always moves to the beginning or 
end of the current line, while shift-Home and shift-End always 
invoke the buffer functions (mark and copy).

Revision of function key assignment.
F12 is no longer attached to the diacritic transformation function 
(assignment had been inadvertently overridden for some releases already), 
as on some (many?) terminals F12 cannot be distinguished from shift-F2.
New function assignments:
F12	enable memory for file positions in current directory
F11	(unchanged) low/capital letter toggle
shift-F11	low/capital toggle for whole word from cursor (like HOP F11)
control-F11	diacritic transformation, e.g. ae->æ
ctrl-shift-F11	(like HOP ESC U) transform Unicode value into character
shift-F2	write file even if unmodified
control-F2	save file as (prompt for new name, then save)
shift-F4	write paste buffer to file
alt-Insert	replace text just pasted with preceding paste buffer
control-F4	replace text just pasted with preceding paste buffer
shift-Home	mark position
shift-End	copy to buffer
control-Home	go to line beginning
control-End	go to line end
Home		(default) mark position
End		(default) copy to buffer
Home		(with -k option) go to line beginning
End		(with -k option) go to line end
Home/End	(on small left keypad) reverse function of right Home/End
HOP shift-F8	search for definition of current identifier (using tags file)
HOP control-shift-F8 search for identifier definition (prompts)
HOP control-F8	search for current character (new function)
VT100: Find	search
VT100: Select	mark position
VT100: Do	copy to buffer
control-Up	(new, see below) move to previous paragraph beginning
control-Down	(new, see below) move to next paragraph beginning
control-Ins	copy to buffer
control-@ (control-space) mark position

New commands to move to previous/next paragraph boundary:
control-Up, control-Down (hold control key and press cursor up or down).

The current text position is pushed on the position stack also with 
the Goto Line/% command (^G).


Enhancements in terminal operation:
-----------------------------------
Tweaked screen attribute handling to improve behaviour of certain 
terminals that do not match their termcap entry (esp. cxterm).

Tweaked screen handling for menu borders to provide workarounds 
for various weird terminal behaviours (esp. mlterm and linux console).

Moved some ambiguous function key escape sequences into a special 
table that is (automatically) only selected if a vt100 terminal 
is set up (by the TERM variable). Added assignments for shifted 
function keys of certain terminal emulators.


Further Enhancements:
---------------------
When a menu is open, the cursor-left or cursor-right keys cycle 
through the pull-down and flag menus.

Added smart quotes style for Japanese corner brackets.

Smart quotes style can also be preselected with the environment 
variable MINEDQUOTES which should then contain the opening/closing 
quote pair or just the opening quote mark.

Renamed X resource configuration plug-in .Xdefaults.mined to 
Xdefaults.mined for better handling and to comply with other 
packages' usage.

Enhanced the script to generate man pages from HTML to handle tables.
Fixed manual page generation to filter out empty lines which spoiled 
the layout.

Manual:
* Added discussion of the disputed keypad function assignment into Key 
  layout section.
* Moved HOP section right behind the Key layout section.


Options:
--------
New option -* to disable mouse support (requested by an emacs mode 
user who prefers to use the xterm copy/paste mouse function).

Option +V to enable emacs-style paste buffer functions for "delete 
word" and "delete to end of line" commands (^T, ^K), and place the 
cursor behind the pasted region after buffer insertion.
(May become the default in a future version, disabled by -V.)

New option -QX to select the style of menu borders where X is one of
	s: simple border, 
	r: rounded corners, 
	f: fat border, 
	d: double border, 
	a: ASCII border (can be combined with another option -Qs or -Qr), 
	v: VT100 alternate character set graphics border, 
	@: reverse blank border.
Mined sets an appropriate default based on its assumptions of the 
terminal capabilities.

Latin-1 or UTF-8 character encoding can now also be selected with 
the -E option: -EL, -EU.


Bug fixes in CJK handling:
--------------------------
Removed length restriction on keyboard mapping multiple choice 
menu, thus enabling Pinyin input method to work.

Fixed mnemonic character input problem in CJK mode.

Fixed handling of unmapped Unicode characters in CJK terminal mode 
in input method selection menu, avoiding ragged menu borders 
(but leaving empty entries for menu consistency between encodings).


Bug fixes with paragraph justification:
---------------------------------------
Fixed paragraph justification on lines with two successive blanks 
(as used after a sentence by some people) which could actually wrap 
lines between the blanks (and leave leading blank on the next line) 
if the right margin happened to be at that point.

Fixed clever paragraph justification on lines without blanks which 
used to change the right margin.

Fixed a display handling bug that could lead to wrong display after 
invoking paragraph justification from the menu.


Bug fixes with screen display:
------------------------------
Fixed interference of Unicode line end display (-uu) with 
paragraph end display (-p).

Fixed menu width handling (esp. when HOP was entered in an open 
flags or popup menu near the right screen border) which could wrap the 
menu display around the screen.


Further bug fixes:
------------------
Fixed missing resp. overridden recognition of Alt-Enter in some 
situations (used for jumping in the cursor position stack).

Fixed handling of keyboard mapping selection menu in right-to-left 
terminal (e.g. mlterm) near the end of text which could crash mined.

Tweaked ESC D and ESC A commands to insert decimal resp. octal value 
of whole character, not of separate encoding bytes. Behaviour is now 
as it was already documented.

Fixed HOP ESC U command which (by the HOP prefix) inserted a pair 
of parentheses if invoked on the code of an open parenthesis.

Fixed inadvertent setting of restricted mode on "-" options prefix 
(since version 2000.7).

A function key entered on the prompt line does no longer abort 
prompting but just beeps.

Fixed explicit cursor marking in proportional terminal mode in 
CJK text mode.


<a name=2000.7>
=============================================================================
Changes from mined 2000.6 -> mined 2000.7 (May 2003)
=========================================

Features:
---------
Enhanced support for character input methods, especially for 
East Asian (CJK) character ranges; selection menu for keyboard 
mapping choices ("pick list").
Pre-compile-time configuration of additional mappings is provided, 
usual mapping tables of other editors can be used as source.

Support for editing files in different CJK encodings, also in a 
UTF-8 terminal. The apparently major encodings in use are supported:
Big5 (with HKSCS), GBK (> GB2312, EUC-CN), UHC (> EUC-KR), EUC-JP.
These are tried to auto-detect by heuristic counting of character codes.
An option to select the encoding (-EX) or auto-detection are also provided.
Two more encodings supported but not auto-detected are Japanese 
Shift-JIS encoding (including single-byte mappings to Halfwidth Forms) 
and Korean Johab character set and encoding.


Enhancements:
-------------
Added flag menus to all flags (except HOP indication) for more 
intuitive usage.

Enabled repeat function with keyboard mapped characters.

Enabled hex entry of CJK double-byte characters on prompt line in 
CJK mode (-C).

Enabled decimal (in addition to hexadecimal or octal) coded character 
input.

Tweaked script to generate keyboard mapping table from yudit keyboard 
mapping file: strip final blank if contained in all entries, skip 
intermediate dummy blank.

Enhanced UTF-8 auto-detection so that longer UTF-8 sequences are 
not ignored.

Flag indication for combined/separated display mode (of Unicode 
combined characters) was tweaked to make it more intuitive.

Added "+", "-" and various Unicode bullet characters as numbering 
items for clever justification (triggering indentation).

Activated colour usage for line markers and scrollbar in CJK terminals 
(newer versions of hanterm apparently support colour).

In CJK terminals, mapping line markers from Unicode values according 
to effective encoding table, so hopefully matching the right 
CJK character for marker display.

Revised CJK special character input support, fixed illegal character 
handling problems with coded CJK input (also on prompt line).

Revised handling of incomplete CJK half character codes. Don't pad 
them with blank on loading the file anymore.

Revised character counting while loading the file to work with CJK 
and auto detection.

Option +G to enforce using block graphics characters for menu borders 
is now accepted in CJK terminals as newer versions support them.

Makefile for Mac OS X (provided by Tobias Ernst).


Bug fixes:
----------
Fixed a bug that would display control characters (e.g. ^X) entered 
directly on the prompt line in UTF-8 mode as letter X with coloured 
background instead of ^X.

Revised character input thoroughly; fixed deficiencies (since 2000.6 
even crashes, shame on me) if the repeat function was provided with a 
non-ASCII character.

Fixed handling of invalid hex CJK double-byte character insertion.

Fixed undefined insertion of arbitrary character if character insertion 
from character code in text (HOP ESC U/D/O) didn't recognize a number.

Fixed insertion of partial character bytes when an open menu was 
cancelled by typing a Unicode character.

Fixed failed recognition of bullet character (0xB7) in non-Unicode mode 
as a numbering item for clever justification (triggering indentation).

Removed those RFC 1345 input mnemonics mapping to private use code points; 
fixed some of them to map to valid code points.

Removed -D option; this feature (which did not work in UTF-8 mode anyway) 
may now be achieved with a keyboard mapping if desired.

Fixed erroneous special handling of 0xA0 (as no-break space) in CJK mode.


<a name=2000.6>
=============================================================================
Changes from mined 2000.5 -> mined 2000.6 (Feb 2003)
=========================================

Features:
---------
Arabic ligature joining support:
If the terminal supports right-to-left display (e.g. mlterm)
mined assumes that the terminal also applies automatic joining of 
Arabic ligatures (LAM/ALEF combinations).
Mined supports ligature joining by accounting for the screen position 
accordingly, and by indicating the joining part of the ligature in 
separated display mode similarly to the handling of combining characters.
This terminal handling mode is configured with the option +UU.

New command ESC Return (Alt-Return) to "return to previous position".
On commands that jump away from the current position (HOP Mark, 
File Begin/End, Search, Search Idf definition), the current position 
is remembered in a position stack. The new command ESC Return goes 
backward, HOP ESC Return forward in this "stack".

Added recognition of mouse wheel control sequences and attached 
according behaviour - untested as I don't have a mouse wheel.


Enhancements:
-------------
New key interpretations for shift-Return (shift-Enter) and 
control-Return (control-Enter) to insert Unicode paragraph separators 
and line separators respectively if Unicode line-end handling is enabled.

Improved prompting for hex/octal character input, made more intuitive.

Improved coded character entry on prompt line: added visual feedback, 
added octal option, enabled for non-UTF-8 mode.

Improved mnemonic character entry on prompt line: added visual feedback.

Implicit suppressing of keyboard mapping during mnemonic character input.

Enabled mouse release and movement support in DOS version (DJGCC).

On opening a file, the current position marker is no longer initially 
set to the opening position (as some users got confused with the 
Cut/Paste function); to return to the position e.g. after searching, 
use the new command ESC Return instead of HOP Mark.


Options:
--------
The option -c selects separate display mode on UTF-8 terminals. The 
mode can also be toggled from the eXtra menu or on the C/c flag 
next to the U/L character encoding flag.
The previous option to assume that the UTF-8 terminal that does not 
support combining characters was changed to -cc.

Bidi terminal mode is selected explicitly with +UU instead of 
implicitly (by disabling the scrollbar with -o).

Additional option -8 to set TAB size to 8 (to override TAB size 
being set to 4 by MINED environment variable).

Changed option -J (to set justification level 2 initially) to +jj.

Added option +U to configure UTF-8 terminal operation. This is 
in order to allow defined setting in addition to -U which toggles 
the pre-configured assumption and might turn out to produce the 
wrong assumption.
Changed -U to also set combining mode when assuming UTF-8 mode.
Note, however, that none of these options needs to be used if the 
environment is correctly configured to indicate UTF-8 as it should 
(LC_ALL, LC_CTYPE, or LANG ending on ".UTF-8" or ".utf8").

Added option +UU to configure bidi terminal operation. This mode 
implies UTF-8 and also assumes that Arabic ligature joining 
(of LAM/ALEF combinations) is applied.


Bug fixes:
----------
Display problems in separated display mode (for Unicode combined 
characters) on the status line were fixed, including Arabic joining 
ligatures.

When deleting the last accent in a Unicode combined character (after 
moving the cursor position into the character), the display was not 
updated; this was fixed.

Fixed documentation of some vt100 keypad key assignments (original 
assignments were mangled by Linux console keypad assignments).

Fixed F5/control-F5/shift-F5 and according F6 accent composition 
prefixes and adapted documentation.

Mentioned shift-F2, shift/control/control-shift-F8, shift-F9, shift-F10 
in documentation.

Fixed ^O new line insertion: if the line is terminated with a Unicode 
paragraph separator, a line separator is used for the new line end.

Fixed and adapted behaviour of HOP Return to insert Unicode paragraph 
separator.

Revised character set handling for PC versions; revised accented 
character composition;
accented character display and composition (from 8-bit character range) 
now working in PC versions for either PC or UTF-8 character encoding.

Fixed status line update problem after operations on parts of combined 
characters (e.g. movement onto the combining accent with ^V cursor-right).

Fixed character composition from text [ ESC_ ] to consider characters, 
not bytes.

Search corresponding bracket [ ESC( ] now also works with UTF-8 
multi-byte characters.

Fixed identifier search [ HOP F8 ] to work with UTF-8 characters 
inside identifier.

Included sources for online help in the distribution archive as 
needed for "make install".

Fixed a crash problem with window resize, then display being redrawed, 
then resize again and output being interrupted. Occurred under rare 
and unclear conditions; now ignored.

Fixed makefile.bsd for NetBSD.

Added top level makefile, selecting OS-specific makefile automatically.


<a name=2000.5>
=============================================================================
Changes from mined 2000.4 -> mined 2000.5 (Dec 2002)
=========================================

Feature: Keyboard mapping
-------------------------
Keyboard mapping for various scripts is available in UTF-8 mode 
(both edited text and terminal must run UTF-8).
This maps keyboard input characters or short character sequences to 
characters (or short sequences) in a different script.
In this release, mappings for Greek, Cyrillic, Arabic, and Hebrew have 
been integrated.
An active and a standby keyboard mapping are maintained. They can be 
toggled quickly for text input with ESC k (or Alt-k), also on the prompt 
line (e.g. for searching).
Command overview:
  ESC k toggles between active and standby keyboard mapping
	also on prompt line
  HOP ESC k resets keyboard mapping to none (unmapped input)
  ESC K opens the keyboard mapping menu
	also on prompt line
  HOP ESC K cycles through available keyboard mappings

Note: As some typical keyboard mappings contain ambigous key sequences 
where one may be a prefix of another, a short delay is applied in 
these cases to allow recognition of any such sequence to be mapped.

The current mapping is indicated by its two-letter script tag in the 
flags area (top screen line), clicking on it cycles through the 
available mappings (like HOP ESC K), clicking with the right button 
opens the Keyboard Mapping menu (like ESC K).

With the environment variable MINEDKEYMAP the active or standby 
mapping can be preselected. The value is a two-letter script tag to 
set the active mapping, or it is prepended with "-" to set the 
standby mapping.
Example: export MINEDKEYMAP=-gr will set Greek keyboard mapping standby.
Known script tags are:
  ar -> Arabic
  gr -> Greek
  el -> Greek
  he -> Hebrew
  cy -> Cyrillic
  ru -> Cyrillic


Options and further features
----------------------------
Bidirectional terminal support:
To run mined on a bidirectional terminal (such as mlterm), disable the 
scrollbar with the option -o.
In this mode, when displaying a menu, underlying text lines that 
contain right-to-left characters are cleared first in order to prevent 
display confusion between the terminal's bidi algorithm and the menu 
position.

Mined's "poor man's bidirectional support" (which automatically places 
right-to-left characters to the left of the previous character) was 
disabled by default in order to support mined's operation with 
bidirectional terminals.

Script colouring:
For better recognition of letters that belong to a certain script 
(where similar looking letters may belong to other scripts), 
text display uses colours to distinguish letters of various scripts.
This is preconfigured for Greek and Cyrillic (which share some letter 
forms with Latin).
Compile-time configuration of further script colouring is available 
with the file colours.cfg; it contains entries with the script name 
(as listed in the Unicode data file Scripts.txt), white space, and 
a colour index into the xterm 256-colour mode.

Two "flag menus" were introduced:
* one for the Keyboard Mapping (as described above),
* the other for Smart Quotes selection; it's popped up with the right 
  mouse button on the smart quotes indication in the flags area;
  additional commands:
  ESC Q or Alt-Q: also pops up the Smart Quotes menu
  HOP ESC Q: cycles through available Smart Quotes

When a pull-down menu is opened with the middle mouse button, the 
HOP version of its items is preselected (can be toggled with middle 
mouse button as before).

-X disables display of the filename in the window title bar.

Changed default of -G option (enabling display of control characters 
as block graphics) to be disabled.

Flag indications were slightly tweaked in order to make them more 
intuitive.


Bug fixes:
----------
Fixed a rare bug with ESC u on illegal UTF-8 characters.

Clever justification now also considers the bullet sign as a 
numbering (list item) character.

Back-TAB was tweaked not to apply directly below non-space text of the 
previous line.

Fixed some bugs and inconsistent results with shortcuts for 
composed character input.
Added composed character sequences for single-accented extended 
Latin characters.
Extended diacritic transformation function (ESC _) to all 
two-letter composed characters as configured for input support.


<a name=2000.4>
=============================================================================
Changes from mined 2000.3 -> mined 2000.4 (Sep 2002)
=========================================

Interface:
----------
Made use of advanced xterm mouse tracking modes.
* Text select and copy with highlighting by mouse dragging.
* Menu item browsing by mouse dragging.
  If the mouse button is kept down, items are automatically selected 
  as the mouse is dragged over them.
  An item is selected by either clicking the left button or 
  releasing the left or right button.
  It is also still possible to open and change menus with click-release, 
  then select an item with another click (less finger-strain).

A "non-break space" (character value A0 hex) is now displayed by a 
tiny middle dot (as used for TAB indication) in cyan colour.

Syntax highlighting
* Also toggled for .sgml files (as well as for .html/.htm, .xml, .jsp).
* Extended to JSP and HTML comments.

In order to avoid command confusion on slow remote connections where 
escape sequences might come in deferred, the following commands were 
changed:
* Disabled ESC N cmd which repeated the command N times when N 
  has only 1 digit (in that case the command might have been a 
  function key escape sequence).
  Use ESC = N cmd instead, or use 2 or more digit repeat counts, 
  e.g. ESC 77- (to enter 77 '-' characters) or ESC 07x (to enter 'xxxxxxx').
* Changed ESC O which inserted the octal value of the current character.
  Use ESC A instead.

When inserting an HTML marker on the prompt line (commands ESC H, 
HOP ESC H) HTML tag attributes can be included; they are only inserted 
for the starting marker, not for the closing marker.

The TAB width can be toggled between 8 and 4 while mined is running 
(command ESC T).

Function keys of some terminals (esp. HP and Siemens) are ambiguous; 
the preferred key set to be detected can now be configured 
(environment variable MINEDTERM= xterm / hp / siemens).

The ESC u command displays additional Unicode script information.

The parentheses matching commands ESC ), ESC (, etc, now also match 
HTML tags.

The character compose and input support function was revised. 
Accent prefix functions were extended to support Unicode. 
Additional mnemos were enabled, including TeX and HTML mnemos.


Features:
---------
Clever justification (auto-indentation):
With the justification command ESC j, clever auto-indentation is applied.
It uses heuristic detection of numbered items and program source comments.
(The old justification function that only considers configured margins 
is available by ESC J.)

A Back Tab function was added. A Backspace from a position that is 
only preceded by white space on the line will revert the input position 
to the previous matching indentation level.

In both justification modes, automatic suppression of auto-indent 
applies by heuristic detection of the speed at which characters 
are entered. This is to allow unmodified pasting of text (using 
e.g. xterm mouse copy/paste).

Checkout and checkin functions for version management systems added 
(to File menu, command scripts "co" and "ci" must exist in path).

Introduced generic handling of shift state indication for function key 
escape sequences (control/shift/alt and combinations).
No more "Unknown command" errors on unregistered function key variants.
By default they invoke the same function as the unshifted key.

The location of mined buffers can be configured with an additional 
environment variable MINEDTMP ([SYS$]MINEDTMP on VMS). This supports 
copy and paste operations among different machines.


Bug fixes:
----------
Revised case conversion and other Unicode character property handling.
Updated tables for wide and combining characters to new Unicode data.

Fixed some display bugs:
- Current line was cleared after prompt was aborted with mouse button.
- Search/replace including linefeeds could mess up the screen.
- Screen line could mess up on an incomplete UTF-8 sequence at the end 
  of a line in UTF-8 text and screen mode.

Fixed a bug with automatic line-wrap after entering space.

Fixed some terminal size detection problems after rlogin from DOS.

Under weird circumstances, the first empty line in a file not edited as 
the first one could produce display and buffer garbage on SunOS.

Fixed some search pattern match bugs:
- with empty lines
- with replace and ^, starting in middle of a line (started replacement 
  at that position, not at start of next line)
- with ^, searching backwards (did not find in current line)

Removed restriction of regular expressions with Unicode characters:
search patterns ä* etc (UTF-8: Ã¤*, â‚¬* etc) do work now.


Manual hints and clarifications:
--------------------------------
A search pattern [pat]* matches a (zero or more times) repetition of 
this pattern. In a final position within the search expression, 
however, it matches one or more times this pattern.

Hex input code ^V # xxxx [space or RET]:
Works on the prompt line only in Unicode mode, exactly 4 hex digits 
are accepted but are not echoed on the screen.

Improved description of special character input support in the manual.
Added overview chapter on input support.


<a name=2000.3>
=============================================================================
Changes from mined 2000.2 -> mined 2000.3 (May 2001)
=========================================

Documentation:
--------------
The manual page was updated and thoroughly revised.
Its primary source was transformed into HTML, roff/man format being 
generated.

The mined web pages were updated and revised.

The file "doc/compilation" (with compilation hints) was updated.


Features:
---------
HOP '/' enters an indented Javadoc comment frame.


Interface:
----------
Options can be concatenated on the command line.
(mined -uu instead of mined -u -u enables Unicode line separators.)

Right-to-left script input support is now enabled by default.
The option -b toggles it.

Option -G disables (actually toggles) the display of certain control 
characters as block graphics characters (enabled by default).

Option +G enforces use of block graphics for display of menu borders.
May be used if the "alternative character set" capability is not 
configured in your system but your terminal does have the capability.

Set output delay (-d0..-d9) to none (-d-) by default in all versions.

The help command was unified on Unix and DOS versions. Not completely, 
however, as calling a sub-programm ("less") through the "system" call 
doesn't seem to work on DOS (it crashes or blocks terminal input 
afterwards, even with cygwin). See also next comment.

A second help viewing mode is now avaible (HOP HELP, e.g. HOP F1). It 
displays help information within mined itself, restoring the previous 
editing state afterwards.
This is the default on MSDOS for the reason mentioned before.


Bug fixes:
----------
Fixed a screen-related pointer confusion after replacement with multiple 
lines (embedded newline) which could result in a display bug and page down 
could be blocked.

(Very minor) Just deleting the trailing line-end of a file is also 
considered a modification (a file only modified this way would 
previously not have been saved automatically).

(Minor) With UTF-8 auto-detection involved, the character count after 
reading the file could be wrong (ESC ? would have been correct).

(Minor) The pop-up menu, when modified with HOP and thus becoming smaller, 
used to leave the frame of its previous width on the screen.

(Embarassing) Although I was proud of "perfect responsiveness to 
window size changes" I had just forgotten to implement that for 
the case of a menu being open.

On DOS, editing a file with Unix line-ends, the function "append to buffer" 
used to append the lines with MSDOS line-ends.


<a name=2000.2>
=============================================================================
Changes from mined 2000.1 -> mined 2000.2
=========================================

Features:
---------
Auto indentation when entering a new line.
Insert a new line without auto indentation with the ^O command.
Auto indent mode may be toggled from the Extra menu.

Entering auto-indented pairs of parentheses:
With the HOP prefix, the characters "(", "[", "{", "<" enter 
an auto-indented pair of "{" ... "}" etc.

Search and replace patterns can use an embedded newline. Enter 
with ^V ^J. In some cases there are still display problems. 
Then update the screen with the ESC "." command.


Interface:
----------
HTML files (ending on .html, .htm, .xml, .jsp) trigger a display mode 
which distinguishes HTML tags by coloured display.
The mode can be toggled from the Extra menu.
	While you edit within a line and change its HTML ending status 
	(by entering or deleting '<' or '>'), the display status of 
	subsequent lines is not changed. (You may refresh the display 
	with ESC ".")

Special markers (on cyan background) for illegal UTF-8 sequences are 
applied in UTF-8 terminal mode as well (instead of the Unicode 
replacement character).

The online help file format and help invocation were changed.

Online help contents was enhanced.


Bug fixes:
----------
For relevant file close operations, the return code of close() is now 
checked. Usually, write errors are already noted by write() calls but 
for a few rare cases, this check is appropriate.

Some display bugs (especially with UTF-8) were fixed.

Graphic display for menu borders on the Linux console was fixed (funny 
it uses the DOS character set as an "alternative character set").


Porting:
--------
Flexible selection of DOS versions available, all with mouse support.
(djgpp, cygwin, EMX, Turbo-C).


<a name=2000.1>
=============================================================================
Changes from mined 2000 -> mined 2000.1
=======================================

Features:
---------
Configurable automatic smart quotes (" character on input replaced 
by typographic quote marks depending on style setting, in UTF-8 text mode).

Completed combined character support, removed some bugs.

Unicode case toggle handles context-dependent mappings (Greek sigma).


Interface:
----------
Mined looks for its online help file at certain typical locations so 
it may find it even if MINEDHELPFILE is not configured.


License:
--------
For distribution purposes, the GNU license was imposed, but commented in 
README.


<a name=2000>
=============================================================================
Changes from mined 98 -> mined 2000
===================================

Features:
---------
Scrollbar display
May be used for relative or absolute positioning with the three mouse 
buttons.

Flexible and simultaneous handling of different line ends
Unix and MSDOS line ends can be handled in the same editing session and 
are indicated by different coloured line-end symbols. Files without 
trailing line-end can be edited and created.

Transparent long line handling
Overly long lines are now read in transparently. They are attached a "NONE" 
line-end type so they will be written out exactly as they came in.
Splitting within UTF-8 sequences is avoided; splitting of combined 
characters is not avoided, however, they will join seemlessly as lines 
are joined again. (Combining characters at the beginning of a line are 
not displayed in combined display mode.)

Special line-end handling details and binary transparency
With the above two modifications, a couple of line end handling features 
were introduced and binary transparency was achieved.
* Input of NUL characters from file is accepted and is presented as a 
  special "NUL" line-end type. Explicitly entering a NUL character 
  works, too (either literally or with ^V # 0). Thus mined achieves 
  binary transparency through an editing cycle now.
* The ^O command in a line with "NUL" or "NONE" line-end will 
  reproduce this line-end type in contrast to entering a new-line 
  which will always produce a real line-end.
* In order to split a line in two, separated with "NONE" line-end, use 
  HOP ^O (e.g. ^G^O).

Mac line-end handling
Mac line ends (CR only) can be transparently read and handled with the 
command line option +R (while -R would transform them into Unix line ends).

Tags file support
Moving to the definition of an identifier using the tags file 
(generated by the ctags command) was added. If a new file is opened 
for this purpose, the current file is saved automatically.
* Command: ESC t when cursor is on identifier (with HOP, it prompts for 
  the identifier), or from Search or Popup menu.

Search and replace enhancements
Finally, typical Unix tool limitations of line orientation is being 
removed. Mined can search for expressions with embedded new-lines 
(enter with ^V ^J or \n). - Not yet fully implemented! -

Additional HTML tag input support
The command ESC H (not ESC h!) now inserts an HTML tag which is 
entered in dialog. Another ESC H inserts the corresponding closing tag.
* So, continuous entering of HTML contents was made easier.
* The previous function to embed the text between marked position and 
  current position in an HTML tag is available with an additional HOP, 
  e.g. ^G ESC H.

File handling consistency improved
The command ESC # to edit the nth file from the command line was 
extended with ESC # # which just reloads the current file.

Remembering editing information between sessions
In addition to the current position, also the paragraph justification 
margins (wrap-around margins) are remembered until the next 
invocation, but only if justification mode is switched on.

Tab size can be adjusted to 4 (instead of 8) with the command line 
option -4.

Keypad assignment to the "Home" and "End" keys can be changed with the 
option -k. Normally, these keys perform the "Mark" and "Yank"("Copy") 
functions. Some people strongly expect these keys to go to the 
beginning or end of line although that really is a waste of key 
assignment as these functions are easily performed with HOP left/right -
anyway, the option -k exchanges the assignment. The other functions 
are accessible with shift-Home/shift-End (if the keys emit different 
sequences, see X configuration hints).


Unicode handling features:
--------------------------
Combined character display
Handling of Unicode combined character display is enabled by default 
with UTF-8 terminal operation. (May be disabled by environment 
variable utf8_no_combining_screen, or command line option -c.)
* There are two editing modes for combined characters: combined and 
  separated. Switch modes by clicking on the "c/C" indicator next to 
  the UTF-8 "L/U" indicator in the flags area of the top line, or in 
  the eXtra menu.
* In combined display mode, the following special functions are available:
  The cursor can be moved into a combined character with 
  ctrl-left-arrow or ctrl-right-arrow, provided these cursor keys are 
  configured to emit distinguished escape sequences with control-key 
  held. ^V-left-arrow and ^V-right-arrow also work. You can determine 
  the exact position of the cursor if permanent character info is 
  switched on (by HOP ESC u or with HOP in the eXtra menu).
* Partially editing combined characters:
  * If the cursor is on a combined character, delete next character 
    will delete the whole combined character, with all combining accents.
  * If the cursor is within a combined character, delete next 
    character will delete the current combining accent only.
  * In separated display mode, all cursor and text modification 
    operations work on the combining parts as displayed.

Search expressions
The restriction that search ranges could not be used for non-ASCII 
characters in UTF mode was removed.
* Search ranges can, however, not be very large as all included 
  characters are listed in an internal buffer which is limited to ca. 
  1 KB.

Case toggle
The character or word case switch function (e.g. in the eXtra menu, or 
F11) works also with all Unicode characters.

Unicode line ends
Line separator and paragraph separator are optionally detected and handled.
* Activate this mode by two -u options ("-u -u" on command line or 
  "uu" in MINED environment variable).
* Inserting a new line on a line with Unicode lineend will insert a 
  line separator unless the hop flag is active in which case a 
  paragraph separator will be used.

Basic input support for right-to-left scripts
After entering a right-to-left character, the cursor position is moved 
left of it, so subsequent characters will be appended left and the 
text shifted right. Characters are stored in visual order while input 
support is implicit, based on the characters being typed. Entering 
left-to-right characters will obviously automatically switch 
direction; to continue with right-to-left, the cursor must be moved 
manually (e.g. to the line beginning).
* Newline, Space, TAB, and combining characters attempt to behave well 
  according to what was entered before; however, intermediate cursor 
  movement is not considered.
* Activate right-to-left support with the command line option -b.
* This mode is not meant to work with the latest right-to-left xterm 
  patch - it would rather interfere with it. The mined right-to-left 
  mode is just intended to provide a simple mechanism to quickly enter 
  visually correct right-to-left text in a conventional environment.
* Orientation of text alignment remains on the left side in this mode. 
  Suggestions for improvement in order to make it useful for 
  right-to-left or bidirectional writing are welcome.


Interface:
----------
Menu display
Uses block graphics characters if determined to be available.

Menu layout
The pulldown and popup menus are in variable width now (depending on 
contents).

HOP toggle in menus
While a menu is open, any of the HOP key, ^G, Blank, or the middle 
mouse button toggles the HOP amplifier and the menu redisplays with 
function names changed where applicable.

Mouse usage
Was enabled with curses operation (useful for EMX, see below).

Keyboard availability of menus
Menus are available from the keyboard; Alt-letter (or ESC-letter) 
pulls down a menu starting with that letter, Alt-TAB pulls down the 
file menu, Alt-blank pops up the quick menu.
(In order to make Alt work as a modifier, set the xterm resource 
metaSendsEscape to true as suggested in the example file .Xdefaults.mined.)

Line begin/end keys, hop key assignment
In order to get rid of the waste of keyboard assignments which is imposed 
by terminal emulation emitting the same escape sequences for keys of 
the two keypad areas, some X resource definitions were included 
in the file .Xdefaults.mined as a recommendation (section 
XTerm*VT100.Translations). Also the hop key may have to be made available 
explicitly with some X setups (also included in that file).

Keyboard reassignments
In order to make room for the Alt-keys to address menus, some 
commands had to be reassigned:
substitute:	ESC , (was: ESC s)
set marker n:	ESC m (was: ESC ,)
screen smaller:	ESC % (was: ESC m)
screen bigger:	ESC & (was: ESC M)
case toggle:	ESC C (was: ESC f)
edit other file: use F3, or "Open" from the File menu (was: ESC e)
print buffer:	use "print buffer" from the File menu (was: ESC p)


Operation in system environment:
--------------------------------
Window resize propagated to parent shell
If the window is resized, the SIGWINCH signal is propagated to the parent 
process so that e.g. the shell also knows about the changed size.


Porting:
--------
Windows ports
Adaptations to enable compilation in Cygwin and EMX environments.
Works in EMX with ncurses and mouse enabled.

Windows port with mouse / DOS port?
A lot of changes to the curses adaptation enabled seemless operation 
in the EMX environment under Windows.
Unfortunately, EMX does not keep its promise to generate dual-mode 
Windows and DOS executables. Can anyone help?


Bug fixes:
----------
Searching
Fixed a few pattern matching bugs (some had slipped in while 
introducing UTF-8).

Search/Replace
Fixed start of replacing to current position (instead of line beginning).

Search/Replace
Fixed a display bug when replacing was aborted with "line too long" 
outside the current screen.

Word-wrap
Paragraph justification moved to the wrong position if triggered by a 
space entered at the end of line.

Chinese mode display
In 8/16 bit character set mode, some situations (illegal 16-bit codes) 
of display garbage were fixed.

Various minor bugs

<a name=6>
=============================================================================
Changes from release 5 -> mined release 6 (1995)
================================================

-	Additional word-wrap version:
	In order to remain a pure text editor (without placing text 
	processing control codes into the text), mined uses trailing 
	blanks as indicators that a paragraph continues. However, 
	sometimes text should be formatted that does not follow this 
	convention. So there is another adjustment option now which 
	terminates formatting a paragraph at the next empty (or blank-
	only) line.
-	Optionally remembering the position where you last left a 
	modified file. Automatic re-positioning in next edit session.
-	Help can now be viewed with mined itself (HOP ESC h).
-	Increased portability: Mined now compiles on more platforms 
	without changes (HP-UX, AIX, recent SINIX versions).


<a name=5>
=============================================================================
Changes from release 4 -> mined release 5
=========================================

-	The command ESC H to insert HTML commands.
-	Separate left margins for first and next lines of paragraph.
-	Startup search expression on command line.
-	Wild cards in file names on MSDOS.
-	Can switch between edit and view only modes.
-	MSDOS version: Beep modified to use the BIOS beep which is 
	redirected by some "beep enhancement" drivers (newbeep / 
	nusound) instead of the DOS beep which for some peculiar 
	reason they don't change.
-	Compiles on SunOS5.
-	Sets window headline and icon text to current filename in 
	xterm or sun-cmd window.
-	Parameter -x to make a new file executable (Unix) in order to 
	create a shell script.
-	Leading "~" notation for referring to home directory accepted 
	in all filenames.


<a name=3>
=============================================================================
Changes from release 2 (August 1992) -> release 3 (August 1993)
===============================================================

Main new features:
-	Paragraph reformatting with left and right margin settings.
-	Optional WordStar-compatible keyboard layout.
-	Optional support of 16-Bit character sets.
	(Works well with the Chinese xterm, cxterm.)

Some more new or enhanced features:
-	Screen display was modified to build from the new cursor position 
	(after a search often in the center of the screen) up and down to 
	the upper and lower borders of the screen. This appears to more 
	naturally suggest to the users where they are.
-	Support for proportional screen fonts was added.
-	The MSDOS function key sequences were activated in the Unix version 
	as well to enable using Unix mined remotely from a PC keyboard.
	PC terminal support includes video mode changing as far as it 
	can be performed by escape sequences to the ANSI driver.
-	Mostly unified option environment into one variable, MINED.
-	Options for conversion between different line end types.
-	Extended the enter-control-code prefix (^V) to compose characters 
	if the first following key resembles an accent mark ("'`^°~).
-	A search for identifier at current position function was introduced.
-	A repeat previous search (one before the last search) function was 
	introduced.

Improvements in the MSDOS version:
-	Improved memory management (problem: the 640 KB memory restriction 
	being effective if compiled with Turbo-C).
-	MSDOS mined now detects screen size changes on each keystroke, so 
	it reacts almost immediately, e.g., on font changes performed by 
	the VGAMAX font substitution TSR.
-	Several MSDOS screen mode switching functions were integrated to 
	enable explicit mode change with a command.

Bugs removed:
-	Display garbage in very small windows (less than 28 columns).
		There may still occur display garbage if the window is 
		narrower than the tab size (8 displayable characters).
-	Display garbage in very long lines.
-	Display and position bug related with tab characters and long lines.
-	Display garbage after substitution that made a line shorter so it 
		gets completely shifted out of the left display border.
-	Incorrect display after aborted substitution.
-	Aborted substitution although there was enough room on the line.
-	If the environment variable NoCtrlSQ or NoControlSQ is set, also 
	the tty channel soft handshake setting will not be disabled in case 
	this would affect remote connection behaviour. I had discovered that 
	characters were actually lost on a remote (internet) login connection.

Keyboard assignment mofications:
-	Line replace function assigned to ESC R.
-	Double assigned some functions in support of optional WordStar mode.
-	Option to adapt Backspace and Delete keys to other convention.


<a name=2>
=============================================================================
Changes from release 1 (July 1992) -> release 2 (August 1992)
=============================================================

Minor changes of behaviour
-	Control characters can now be searched for.

Source improvements
-	Improved portability according to mail feedback.
-	Compiles without warnings with gcc -ansi -pedantic and 
	various other checks.

MSDOS version
-	Compatibility with different ANSI drivers was improved.
	Runs well with the very capable NNANSI (Tom Almy) or the 
	small and simple well-working ANSI.COM (Michael J. Mefford).
-	Workaround for problem with Turbo-C libraries that inhibited 
	mined from working in arbitrary size screens ("extended text modes" 
	like 132x44 etc).
-	The change working directory command now works with respect to 
	different drives, including change of drive only.
-	Shell escape now available on MSDOS.
-	A display bug on the prompt line of the search/replace commands 
	was removed (The initial prompt vanished after the first input).
-	Options can be given starting with / in addition to - .
