Hi,

I am pleased to announce the release of ATS2-0.2.9.

This is the 32nd release of ATS2, the successor of the  
ATS (currently referred to as ATS1) programming language. The  
compiler for ATS2 is given the name ATS/Positats, ATS2/Postiats  
or simply Postiats.

The official website for ATS is:

[http://www.ats-lang.org](http://www.ats-lang.org)

ATS-Postiats is hosted at github:

Major releases of ATS2 are available at:

Major releases of external packages for ATS2 are available at:

A google-group for discussing ATS and related issues is at:

[https://groups.google.com/forum/?fromgroups#!forum/ats-lang-users](https://groups.google.com/forum/?fromgroups#!forum/ats-lang-users)

The following packages are included in this release:

ATS2-Postiats-0.2.9.tgz # requiring libgmp  
ATS2-Postiats-contrib-0.2.9.tgz # contributed packages  
ATS2-Postiats-include-0.2.9.tgz # CATS-files w/ BSD-like license

I have included ATS2-Postiats-contrib (instead of releasing it  
separately) as it is truly by now an indispensible part of ATS2.

After installing ATS-Postiats-include, one can compile the C code  
generated from ATS source without installing the ATS compiler. So  
a convenient way to distribute software written in ATS is to simply  
release the C code generated from the ATS source.

See below for some major additions and changes since the last release  
(ATS2-0.2.8).

Here is a list of major additions and changes since the last release:

1. Adding support for streamize-functions
2. Including the patsopt version into the C code generated by patsopt
3. Greatly improving support for programming with combinators in general
4. Support in atscc2erl and atscc2scm for handling tail-call optimized code
5. Atscc2clj/libatscc2clj starts to be functional (but yet a long way to  
go!)
6. Initiating testing for ATSLIB (see ATS2-Postiats-test/core/ATSLIB for  
more)

Cheers,
