On behalf of the Python development team, I'm happy to announce the
second beta preview release of Python 3.2.

Python 3.2 is a continuation of the efforts to improve and stabilize the
Python 3.x line.  Since the final release of Python 2.7, the 2.x line
will only receive bugfixes, and new features are developed for 3.x only.

Since PEP 3003, the Moratorium on Language Changes, is in effect, there
are no changes in Python's syntax and built-in types in Python 3.2.
Development efforts concentrated on the standard library and support for
porting code to Python 3.  Highlights are:

* numerous improvements to the unittest module
* PEP 3147, support for .pyc repository directories
* PEP 3149, support for version tagged dynamic libraries
* PEP 3148, a new futures library for concurrent programming
* PEP 384, a stable ABI for extension modules
* PEP 391, dictionary-based logging configuration
* an overhauled GIL implementation that reduces contention
* an extended email package that handles bytes messages
* countless fixes regarding bytes/string issues; among them full
  support for a bytes environment (filenames, environment variables)
* many consistency and behavior fixes for numeric operations
* a sysconfig module to access configuration information
* a pure-Python implementation of the datetime module
* additions to the shutil module, among them archive file support
* improvements to pdb, the Python debugger
