Please send mdk bug reports to bug-mdk@gnu.org.
---------------------------------------------------------------------------
* Version 0.4
** Split mode: gmixvm can now be run with the MIXVM, MIXAL and Devices
windows detached (instead of arranged in a notebook).
** When running in split mode, the MIXVM, MIXAL and Devices windows
can be hidden.
** The gmixvm main window displays the path to the current MIX file in
its title bar.
** Bug fix: changes in the device format are now correctly stored (gmixvm).
---------------------------------------------------------------------------
* Version 0.3.5 (23/06/01)
** In gmixvm, when the mouse pointer is over a MIXAL source line, the
status bar shows the value of the variables appearing in this line.
** The current symbol table can be displayed, in gmixvm, using the menu
command Debug->Symbols...
** Bug fix: the load, compile and run file dialogs now get the correct
filename under linux.
** Bug fix: fonts used by gmixvm are now always correctly saved.
** Bug fix: 'psym' now works correctly in gmixvm.
** Bug fix: the symbol table for a MIX file is now correctly recovered
both in gmixvm and mixvm (negative values where incorrectly
converted to a positive value).
---------------------------------------------------------------------------
* Version 0.3.4 (12/06/01)
** Bug fix for a segfault which made gmixvm unusable in version 0.3.3.
---------------------------------------------------------------------------
* Version 0.3.3 (10/06/01)
** 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 command, DOWN for next one).
** 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)
** The GNU MDK documentation is now distributed under the GFDL
license.
---------------------------------------------------------------------------
* Version 0.3.2 (10/05/01)
** 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/output 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/GUD 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
