Release Notes CM3 5.8.3
The second release candidate still had several problems most
of which should be corrected now in RC3. For details please see
the roadmap and the
of the CM3 trac service.
Release Notes CM3 5.8.2
There have been a lot of changes and improvements since the last
release of CM3, 5.4.0, in the fall of 2006. Of course there have
been lots of development snapshots and contributed installation
archives for various target platforms since then, but, alas, no
official release. So we're finally there. In case you wonder why
this is release candidate 2 (RC2), that's because the first was
only used internally and not announced here.

Here's an overview of the
Please refer to the change
logs of 2006,
for a complete list of changes. Here's a summary of the
- Updated support for various Windows platforms (native,
Cygwin, Mingwin, Interix). It is possible to use many Microsoft
SDKs (including free ones) as the basis for native support now.
- Many improvements to m3gdb, the Modula-3-aware extension of
the GNU debugger. It's still not perfect, but then, what is?
- System pthread threading is now the default on all
many systems, this allows M3 applications to scale over all
available hardware processors.The original (fast) M3 user
level thread code is still there and can be used if necessary
(on most platforms).
- Many fixes and improvements of the garbage collector.
- Many fixes and improvements of the system pthreads
- There is a new type LONGINT. It is a 64bit signed integer
on all platforms except the native NT "NT386" platform. On NT386
is a 32bits, for now, but we would like to fix that.
- Much improved and restructured CM3 config files.
- Added lots of new quake functions and fixed several quake
- Import of gcc 4.3.0 as code generating backend.
- Support for new 64 bit target platforms
(AMD64_LINUX and others).
- Added CM3-IDE, the open source version of Reactor (tm). This
is a browser-based IDE for Modula-3 developement.
- Extensive refactoring of platform specific interfaces and
reduction of system dependencies.
- Updated and extended quake documentation. Improved
miscellaneous other documentation. Updated all generated source
documentation for all packages.
- Addition of manual pages for cm3, quake, m3makefiles.
- Several fixes for pickling code (object
- Improved allocation code for concurrent use cases.
- Add alternative text implementation which promises much
better performance -- not activated yet, but available for
- Improved dynamic linking support using rpath and $ORIGIN.
- Added CVSup to the CM3 repository.
- Compiler support for the minimal tagged REFANY values.
- Make optimization at level 3 work for the gcc backend.
- Support for many additional targets.
An extensive regression test framework based on
Tinderbox and (recently)
lots of existing tests has been added, which should help to
avoid decrease in quality.
