2004-04-19 Till Tantau <tantau@users.sourceforge.net>

	Version 2.20

	Added:
	- Added style "Separator" in LyX.
	- Added multimedia.sty for movie and sound inclusion.
	- Added evil allowframebreaks option to frames for automatic frame breaking.
	- Added evil shrink option for automatic frame text shrinking.
	- Added squeeze option to frames for squeezing more on a frame.
	- Added \framesubtitle command.
	- Added \subtitle command.

	- Added option usepdftitle=false to suppress automatic generation of
	  author and title entries in pdf document info.

	- Added new version of beamer.el, due to Thomas Baumann.

	Changes:
	- FoilTeX emulation will now do automatic page breaking.
	- Empty lines in "Standard" lyx style will no longer be kept, use
	  an empty Separator line instead. 
	- Changed the qed symbol to an open rectangle.
	- The way frame titles are typeset is completely different now,
	  internally. Under normal circumstance you should not notice any
	  differences, but if you do wicked things with the frame titles,
	  problems might arise.

	Bugfixes:
	- Fixed definition of overlayarea to give better spacing.
	- Fixed problem with persisting background color and dvips.
	- Fixed zillions of typos in the user's guide spotted by 
	  Xavier Noria and Uwe Stoer.

	  This fixes all sorts of problems.

	- Added a seminar emulation layer.
	- Added third level of itemize/enumerate nesting (I don't like it,
	  but some people do).

	  environments. It generalises \pause in a simple, easy-to-use
	  way.
	- Added incremental overlay specifications (very useful).
	- Added beamer.el emacs plug-in, contributed by Thomas Baumann.
	- Fixed problem that caused empty columns to disappear.

	  to get the old behaviour.
	- \footnote now takes an extra optional argument.

2004-02-18 Till Tantau <tantau@users.sourceforge.net>

	Added:
	- Added placement options to columns and column commands.
	- Added \column command.
	- Added label option to frames.
	- Added \againframe command for showing a frame again later on
	  (very useful!). 
	- Added \includeonlyframe command for typesetting only specific
	  frames. 
	- Added \AtBeginSection, \AtBeginSubsection, and \AtBeginPart
	  commands (very useful!).
	- Added \visible command (opposite of \invisible).
	- Added verse, quotation, and quote environments.
	- Added abstract environment (not very useful in my opinion).
	- Added colored option to \defverbatim for use with lstlisting.
	- Added grid density option to grid background.
	- Added professionalfont option.

	  frames that contain a note.
	- Added options to all \insertshortxxx commands.
	- Added option for passing arguments to color, xcolor, pgf, and
	  hyperref.
	- Added \action and actionenv environments.
	- Added the concept of actions to overlay specifications. For example,
	  \item<alert@2> will alert the item on the second slide and
	  \item<2-| alert@2> will furthermore have the item covered before
	  that.  
	- Added <> option to \newcommand and \newenvironment to make the
	  defined commands overlay-specification aware.
	- \only and \alt will now also accept an overlay specification
	  "at the end".
	- Block environments now accept overlay specification also before
	  the argument.
	- Added \mode command

	  available in article mode in a sensible way.

	  (useful for the article version).
	- Started adding some templates for rendering frames in article mode.
	- Added \lecture command and \includeonlylecture (useful for
	  lecture notes).  
	- Added a containsverbatim option to the \frame command. Should be
	  used instead of the old \frame<all:1> (which is, however, still
	  supported). 
	- Made \includegraphics, \pgfimage, and \pgfuseimage
	  overlay-specification-aware. (useful for pseudo-animations)
	
	Changed:
	- Every frame is now put into a box internally. Slides will never
	  be split over two pages.
	- \pause commands now transcends blocks (very useful, but not
	  compatible!) 
	- Balls are now also used for enumerations, not just for itemize
	  in shadow theme. Use \beamertemplateenumeratealpha to get old
	  behaviour. 
	- Changed syntax of alert and structure templates.
	- Reworked internals of overlay management. Should produce
	  slightly shorter files.
	- Changed file names of .jpg and .png images to start with "beamer-"
	  to avoid name clashes.
	- Renamed \original to \beameroriginal because of clash with
	  lucidia font styles.
	- "Streamlined" themes to use the same basic templates.
	- \noteitems replaced by \note[enumerate].

	  instead.

          option bars instead.
	- Removed compressnotes option. Use \beamertemplatenotecompress
	  instead. 
	
	Removed:
	- Removed pauses environment (no longer needed).
	- Improved pgf makes \pgfonly superfluous. Use \only instead.
	- Removed reproducable .pdf example files from repository for
	  faster cvs checkout/checkin.
	- Removed \invisibleon command (was superfluous anyway).
	- Removed \mixinon command (was not very useful and clashes with
	  new \pause command; use \opaqueness instead).
	- Removed \newoverlaycommand and \renewoverlaycommand. Can be
	  better implemented using \newcommand<>.
	- Removed \article, \presentation, and \common commands (still
	  quietly tolerated). Should be replaced by \mode<article>,
	  \mode<presentation>, and \mode<all>. 
	- Removed beamer/lyx/doc. Documentation is now incorporated in
	  the main user's guide.
	
	LyX:
	- Added a big example file beamerlyxexample1.lyx.

	- Changed beamer.layout to use new command \column. Old environment
 	  no longer supported in lyx.

	  the previous frame. EndFrame is only needed before the end of
	  the document, before the appendix, and before "out-of-frame"
	  material.

	  alignments, both for completely invisible covered and
	  transparent covered text.

	  to the color scheme.
	- Added versioning system for head and toc entries. Will no longer
	  do weird things when left over files from an old version are
