Dear friends,

We are happy to announce the release of Mozart 1.2.4.  Many bugs have
been fixed (see the "Changes" document attached below) and the system
is again up to date with respect to newer versions of external
libraries.

You can dowload Mozart 1.2.4 from:

                  http://www.mozart-oz.org/download/

At this time Mozart 1.2.4 is available in source form, as well as in
precompiled binary distributions for the following platforms:

* Linux (RedHat 7.2, 7.3) -- please contribute rpms for other distros
* Debian
* Windows
* MacOS X
* FreeBSD (ELF i486)

Thanks to Marco Kuhlmann for the Debian distro, to Leif Kornsteadt and
Thorsten Brunklaus for the Windows distro, and to Marc-Antoine Parent
for the MacOS X distro.

New distros will be announced as they become available.

PLEASE CONTRIBUTE DISTROS:

For anyone using Linux, it is very easy to prepare RPMs for your
platform: grab the Mozart source rpm from our download site and
execute (as root):

	rpmbuild --rebuild mozart-1.2.4.XXXXXX.src.rpm
or	rpm      --rebuild mozart-1.2.4.XXXXXX.src.rpm

rpmbuild is recommended if available (XXXXXX depends on the last time
I updated the rpm).

1 Mozart 1.2.4

   Mozart   1.2.4  is  a  bug-fix  and  maintenance  release,  with  some
   enhancements.

1.1 Base

   changes and fixes that concern the base language:
     * bytestrings: space now prints as space instead of being encoded as
       octal
     * fixed insertion sort in dictionary.cc (so what?)
     * improved   static   analysis   for  Port.new:  {Port.new s _}  now
       diagnoses the error due to the typo (atom instead of variable)
     * added Value.isFailed: true iff the arg is a failed future
     * Int.'div',  Int.'mod':  work  consistently  and  according  to the
       specification  for  small  and  big  integers  (concerns  negative
       numbers only)
     * Value.waitQuiet no longer blocks on failed futures
     * robustly handle the case of a messed up OZLOAD
     * bug fix for VirtualString.toAtom
     * Sort and Merge are now stable
     * new  environment  variable  OZ_DOTOZ  to  override  default ~/.oz.
       corresponding property oz.dotoz
     * List.take,  List.drop  and  List.takeDrop  no longer unnecessarily
       block on nondet list tail that is not looked at

1.2 Windows

   changes and fixes that concern the Windows platform:
     * fixes to compile again with MSVC
     * debug emulator can be built
     * Control-C should now work
     * configuration:  Updated  to  link correctly under the newest mingw
       (check for either -ldirent or -lmingwex)
     * fixed other problems due to changes in mingw library
     * OS.getEnv:   now   correctly   distinguishes   between   an  unset
       environment  variable and an environment variable set to the empty
       string
     * fixed  Application.getCgiArgs on Windows for newer Apache (same as
       previous item)
     * fixed Open.pipe pbs
     * OS.pipe:  When  the process at the other end of a pipe terminates,
       end-of-file is reported instead of an exception
     * OS.read:  When an end-of-file arrives on standard input, it is now
       correctly reported instead of blocking indefinitely
     * fixed  weird  compilation/linking pbs, actually caused by clashing
       GIDs (see DP)
     * oztool more flexible: supports -I, -l, -L and -s for GNU and MSVC
     * OPI:  fixed  encoding  (on Windows) for sending data with accented
       chars to oz process

1.3 Documentation

   changes and fixes to the Mozart documentation:
     * install: fixed obsolete hrefs, added windows/cygwin info
     * notation: fixed def of "in expression"
     * tutorial: typos

1.4 Constraint Programming

   changes and fixes concerning the constraint programming support:
     * documented limitations:
          + free  var  cannot  be  constrained in subspace: must first be
            constrained in home space
          + number  of  alternatives  of a choice point must be less than
            2^27-2
     * doc/system/fd: fixed typos
     * fixed dis
     * fixed  FDBitVector::findMinElemen to correctly return -1 for empty
       vector
     * fixed  corner  case  that  was  causing  the  infamous  "change of
       representation"   bug   at   64   elements   in   rare   occasions
       (FSetValue::operator <=)
     * domain consistent propagators are now properly woken up
     * \=:  now  correctly  takes  variable  aliasing and entailment into
       account
     * reified  constraints:  fixed occasional misbehaviour due to out of
       bound array access
     * FD.distribute:  bug  fixes  + improvements. (used to not correctly
       synchronize on stability on 1st invocation)
     * FS.distribute:  fixed  to  use stable order, improved, round robin
       bug fixed (used to drop variables)

     * System:
          + documented System.onTopLevel
     * Property:
          + synchronize  on  undet  property values instead of raising an
