[Python-Dev] RELEASED Python 2.5 (alpha 1)

[Anthony Baxter]

On behalf of the Python development team and the Python
community, I'm happy to announce the first alpha release
of Python 2.5.

This is an *alpha* release of Python 2.5, and is the *first*
alpha release. As such, it is not suitable for a production
environment. It is being released to solicit feedback and
hopefully discover bugs, as well as allowing you to determine
how changes in 2.5 might impact you. If you find things broken
or incorrect, please log a bug on Sourceforge.

In particular, note that changes to improve Python's support
of 64 bit systems might require authors of C extensions to change
their code. More information (as well as source distributions and
Windows installers) are available from the 2.5 website:

    http://www.python.org/2.5/

The plan from here is for a number of additional alpha releases,
followed by one or more beta releases and moving to a 2.5 final
release around August.  PEP 356 includes the schedule and will be
updated as the schedule evolves.

The new features in Python 2.5 are described in Andrew Kuchling's
What's New In Python 2.5. It's available from the 2.5 web page.

Amongst the language features added include conditional expressions,
the with statement, the merge of try/except and try/finally into
try/except/finally, enhancements to generators to produce a
coroutine kind of functionality, and a brand new AST-based compiler
implementation.

New major modules added include hashlib, ElementTree, sqlite3 
and ctypes. In addition, a new profiling module cProfile was 
added.

A large number of bugs, regressions and reference leaks have
been fixed since Python 2.4. See the release notes for more.

Enjoy this new (alpha!) release,
Anthony
