     *  [AM] fixed broken axis scaling when set min/max was +/- Inf
     *  [EV] stack manipulation fixed (#417)
     *  [AM] "-version" now outputs to stdout instead of stderr
     *  [ES] misc small fixes

    5.0.0 (since Xmgr-4.1.2):

    New functionality
     *  [ES] T1 fonts are used for all devices using the T1lib library of Rainer
             Menzner. There should be no discrepancies anymore between characters
             displayed and printed (rep. #16)
     *  [ES] routines of drawing layer rewritten from the scratch; Grace is now
             almost WYSIWYG, except patterns (rep. #184)
     *  [EV] generic I/O filtering implemented (including rep. #240); see docs
             for details
     !  [ES] reciprocal axis scale implemented (rep. #33)
     *  [EV] system-wide gracerc ($GRACE_HOME/gracerc) will be read at startup
             time, if exists
     !  [ES] overlined strings are possible (\o \O) (rep. #176). Doesn't work with
             device fonts yet
     !  [MM] extensions to regions including horizontal-inside, horizontal-outside,
             vertical-inside and vertical-outside
     !  [MM] Grace will use the FFTW library for Fourier transform if present on
             the system; see README.FFTW
     *  [MM] negative indices in "Drop points" allowed (counting from the end of
             a set)
     *  [EV] added a new feature to be extracted - the integral of each set
     !  [ES] "unit" and "const" added to the possible proctype's for modules.
             DEG (below) is an example what "unit" can be used for
     !  [ES] DEG and RAD are now meaningful. E.g., expressions like sin(90 deg)
             and sin(pi/2 rad) both are legitimate (and equivalent!) ("rad" can be
             omitted - it's there just for the sake of completeness)
     *  [ES] metafile driver (not in final state)
     *  [ES] PDF driver using the PDFlib of Thomas Merz; see README.PDF
     *  [ES] GIF/GD driver using the GD library of Thomas Boutell (rep. #14); see
             README.GIF
     *  [ES] logarithmic scales can have any base (rep. #370)
     *  [ES] patterns and colors can be used simultaneously (rep. #291)
     *  [ES] power tick label format changed to work in scientific format
             (rep. #361)
     *  [ES] \B in composite strings will reset the font to the string's initial
             font (rep. #388)
     *  [ES] PS/EPS driver rewritten from the scratch
     *  [ES] X11 driver heavily rewritten

    Interface
     !  [ES] removed "Plot/World scaling" popup
     !  [ES] re-designed axis props GUI popup (in particular, rep. #63, #313)
     *  [EV] point ops popup fixes
     !  [ES] graph appearance props GUI popup
     !  [ES] removed "Viewport", "Frame", "Titles" and "Legends"  popups.
     !  [ES] removed "Error bars" and "Edit legends"  popups.
     !  [ES] re-designed set appearance props GUI popup (rep. #311, #369 should be
             fixed)
     *  [EV] added expression evaluation to text input fields in all widgets
     *  [EV] error window changed - only 1 window, not 1 window per error
     !  [EV] regression fits can be applied to specified interval and results are
             printed out in readable form
     *  [EV] scrolled windows for explicitly requested expressions
     *  [EV] canvas hotkeys added
     !  [ES] re-designed print setup GUI popup (problems in rep. #372, #412
             should be fixed)
     *  [ES] changing page size is possible for any device separately; the units
             can be "pix"els, "cm" or "in" (rep. #108, #211, #216, #405)

    Project files
     *  [EV] background color saved
     *  [MM] all regions, whether active or not, are saved to the file, so
             temporarily inactive regions don't get lost
     *  [ES] page size is saved (rep. #312)

    Parser
     *  [ES] cleaned grammar parser; instead of 350 shift/reduce and 231
             reduce/reduce conflicts - > 61 & 0 respectively
     *  [ES] MAX() and MIN() renamed to MAXOF() and MINOF()
     !  [ES] removed DX, DY, IMAGE
     !  [ES] removed GRAPHNO *BAR SIZE NUMBER
     !  [ES] removed SETNUM = SETNUM etc
     !  [ES] removed CMAP, STATUS, STATUSBAR, TOOLBAR, LOCATORBAR, LOCATOR

    Defaults
     !  [ES] default page layout changed from free to fixed
     *  [ES] \+ increases font size sqrt(sqrt(2)) times; \- respectively,
             decreases. Sub/superscripts are 1/sqrt(2) of the preceeding font size

    Portability
     *  [AM] implemented dynamic modules for OS/2
     *  [EV] popen() for VMS
     *  [JH/RN] VMS fixes

             (rep. #215)
     *  [ES] the axes tick marks were behind set curves (rep. #224)
     *  [ES] popup positioning left up to WM for all windows (rep. #273)
     *  [ES] if graph contained too many ticks, autoscale was applied instead
             of tick position recalculation (rep. #275)
     *  [EV] in "Point ops", 'Delete' ignored set number (rep. #293)
     *  [ES] once activated, legends fill frame couldn't be switched off
             from within GUI (rep. #326)
