Please send mdk bug reports to bug-mdk@gnu.org.

*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
   Vasiliy 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
