New URLs for Subversion, Releases, and Bug-tracking
All the Stratego/XT development tools have been moved to subdomains of strategoxt.org. An overview:- At https://svn.strategoxt.org you can find the Stratego/XT Subversion server. Please let us know if there are still old svn.cs.uu.nl URLs around somewhere. If you want to relocate your checkout, run
svn switch --relocate https://svn.cs.uu.nl:12443 https://svn.strategoxt.org. - At http://releases.strategoxt.org you can find releases of Stratego/XT and its extensions. Most of the URLs on the website have been updated to point to this website. If you still have Nix channels subscriptions for the old buildfarm, please update!
- At http://bugs.strategoxt.org we now host our issue tracking system.

Global Variables
Stratego now supports scoped global variables. In the context of a dynamic rules section one can now write
rules( Foo := <compute> )
which abbreviates the following commonly used programming pattern:
x := <compute>
; rules( Foo : _ -> x )
The value bound in the assignment can be retrieved by the application <Foo>.
The usual scoping features of dynamic rules apply to global variable as well.

AspectJ-front revived, support for Microsoft Windows
The AspectJ-front package has been updated to be easier to install and be more portable. The AspectJ syntax definition of AspectJ-front heavily exercises the SDF parser generator, which used to make it rather difficult to install the package on machines with a limited amount of memory. The new packages includes the compiled parse tables and also the package is more portable, including support for native Microsoft Windows! The package now also provides a library (DLL on Microsoft Windows) for parsing and pretty-printing AspectJ source files.

x86-64 support for Stratego/XT!
Stratego/XT supports x86-64 processors (in 64-bit mode) from release 0.17M3pre16744 (or later), the sdf2-bundle from release 2.4pre212034 (or later). The preliminary releases are available from our new Nix buildfarm at the TU Delft. The x86-64 support is based on a branch of the ATerm library developed by Eelco Dolstra and Erik Scheffers, and some new 64-bit patches for the sdf2-bundle. The x86-64 bit requirements are completely hidden in the ATerm library and the Auto/XT build system, thus packages based on Stratego/XT should support x86-64 machines out of the box if they do not contain custom native C code. The preliminary releases with 64-bit support will soon be used in the Stratego/XT packages integration build, which currently still refers to the Nix Buildfarm at Utrecht University. More information about the issues and the specific patches required for x86-64 support is available in a post at Subject to Meta Programming.

Stratego/XT Packages Channel
The Stratego/XT packages channel now provides integration builds for Stratego/XT, its dependencies, and packages based on Stratego/XT. We have created this channel after frequent questions about which packages work together. From now on, this is the way to install the latest developments of Stratego/XT. If you install packages from this channel, then they are guaranteed to work together. If your favorite Stratego/XT package is currently not on the channel, just send us a request. If the package is maintained and in reasonable use, then we will add it to the channel.

New Translation Scheme
By a new translation scheme in the back-end of the Stratego compiler, the dependency on nested functions in gcc has been eliminated. The compiler now produces ANSI C compliant code, increasing the portability of Stratego code in terms of compilers and platforms.

Java-front 0.8 has been released. This is a major update, fixing some usability issues in parse-java, improving the support for compilation the command-line, and fixes in the pretty-printer.Stratego Shell 0.4, the first offical release, is now available! The Stratego Shell implements a Stratego interpreter and an interactive shell for Stratego programming. The interpreter and shell are very useful for learning Stratego and for implementing small tests. 2005-01-14
