** Added guile support. New utility 'mixguile'...
+** New (g)mixvm commands:
+ - psrc: print the current program's source file path
+ - pprog: print the current program's path
+ - pline: print the current program line
+ - pstat: print the current virtual machine status
+ - slog: set on/off the logging of info messages to stdout (or
+ the command log in gmixvm)
+
+** For the sake of coherence, the following (g)mixvm commands
+ have been renamed:
+ - tracing -> strace
+ - timing -> stime (set on/off timing),
+ ptime (print timing stats)
+ - devdir -> sddir (set the devices dir),
+ pddir (print the devices dir)
+
+** In gmixvm, when a font specified in the config file cannot be
+ loaded, it is removed from the configuration.
+
+** Bug fix: when the MIX font is changed in gmixvm, the loc widget
+ font is correctly updated.
+
** Bug fix: help messages are now correctly aligned in (g)mixvm.
** Bug fix: timing statitics for the MOVE instruction are correctly
computed.
+** Bug fix: pressing return at an empty 'MIX >' prompt does not
+ produce an error message.

+Another useful way of using @code{mixguile} is writing executable

+accepts all the command options of @code{guile}; type @code{mixguile -h}
+for a list of all available command options). For instance, if you have
+a very useful MIX program @file{foo.mix} which you want to run often,
+you don't have to fire a MIX virtual machine, load and run it every
+time; you can write a Scheme script instead:
+
+@example
+#! /usr/bin/mixguile -s
+!#
+;;; runprimes: execute the primes.mix program

+;; load the file you want to run
+(mix-load "../samples/primes")
