---------------------------------------------------------------------------
* 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.

** 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).

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

---------------------------------------------------------------------------
* 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
