---------------------------------------------------------------------------
* Version 0.3.3

** The output of the contents of binary devices in gmixvm can be
   configured to be in decimal or word format (for each block device).

** The main gmixvm window is not shown until it is completely drawn.

** The commands 'edit' and 'compile' are now understood by gmixvm. The
   external programs used can be configured using the menu entry
   Settings->External programs.

** The commands 'edit' and 'compile' can be now executed without
   argument (both in mixvm and gmixvm). When no argument is given, the
   MIXAL source file corresponding to the currently loaded MIX program
   is edited/compiled.

** Bug in CON fixed : 'CON wexpr' didn't compile correctly unless wexpr
   represented a valid instruction; now, wexpr can evaluate to an
   arbitrary value (Vasilij Ozmetelenko).

** The completion key for the gmixvm command prompt is now TAB
   (instead of RETURN).
   
** The gmixvm command prompt maintains now a history of previously
   typed commands, which can be visited using the arrow keys (UP for
   previous commands, DOWN for next).

** When a file is reloaded by the virtual machine (both in mixvm and
   gmixvm), the currently set breakpoints are conserved.

** When compiling a source file which is not in the current directory, the
   correct path is now stored in the compiled file.

** Fixed a bug which caused gmixvm to segfault when creating the
   virtual machine (Andrew Hood)

---------------------------------------------------------------------------
* Version 0.3.2 (10/04/01)

** The colors used for highlighting MIXAL source lines in gmixvm are now
   customizable.

** The fonts used used in the different gmixvm widgets are now
   customizable.

** Input/ouput for all MIX block devices is shown in gmixvm.

** All gmixvm customizations are stored in a configuration file
   (inside ~/.gmixvm directory).

** Device files used by gmixvm are stored in ~/.gmixvm, instead of the
   working directory.

** Output to binary devices works now correctly.

** Bug on pmem fixed (thanks to Christoph von Nathusius and Jason
   Uhlenkott).

---------------------------------------------------------------------------
* Version 0.3.1 (9/04/01)

** New binary and html RPMs (RedHat) contributed by Agustin Navarro
   <anp@cantv.net>.

** The package can be correctly build in FreeBSD 4.2 (Ying-Chieh Liao)

** Fixed configuration process when included gettext is used.

** The info files are now properly categorized in a dir entry, so that
   they can be properly installed.

** Compilation warnings fixed.

** getopt implementation provided for systems missing it.

---------------------------------------------------------------------------
* Version 0.3 (28/03/01)

** MDK is now an official GNU package.

** New GTK+ interface for the virtual machine (gmixvm).

** New mixvm-Emacs/GNUD interface via mixvm.el (Philip King).

** Readline and history support for mixvm are now optional features.

** JRED is now properly implemented (bug pointed out by
   Vasilij Ozmetelenko).

---------------------------------------------------------------------------
* Version 0.2 (07/01/01)

** mixvm provides virtual execution time statistics after each
   invocation of run or next.

** mixvm can trace instructions as they are executed. tron/troff
   commands turn on/off instruction tracing.

** mixvm accepts a new command, w2d, which computes the
   decimal value of a MIX word given as a series of
   bytes (e.g. - 01 00 34 32 22).

** Symbols can be defined at the mixvm prompt with the
   new command ssym.

** mixvm accepts a new command, weval, which allows the
   evaluation of MIXAL w-expressions.

** Expressions containing strings of successive '*' are now
   correctly evaluated.

** When using block devices in mixvm, the buffers are now
   flushed after each OUT operation.

---------------------------------------------------------------------------
* Version 0.1.1 (18/11/00)

** MDK is now compilable in rpm-based linuxes.
** MDK fully compliant with Knuth's specification. In particular,
   local symbols are now properly handled in special cases such as 
     3H ORIG 3B 
   instructions. See samples/stress{1,2}.mixal.
** Future references affected by unary minus are accepted
   with a warning (they are banned in Knuth's specification).
   Also future refs in EQU directives are now properly handled.
   See samples/stress{3,4}.mixal.
** When mixvm executes a program and reaches the end of the
   available memory without encountering a HALT instruction,
   it halts anyway.

---------------------------------------------------------------------------
* Version 0.1 (31/10/00)

** Initial version
