[RELEASED] Python 3.3.0 alpha 3

Georg Brandl-3
On behalf of the Python development team, I'm happy to announce the
third alpha release of Python 3.3.0.

This is a preview release, and its use is not recommended in
production settings.

Python 3.3 includes a range of improvements of the 3.x series, as well
as easier porting between 2.x and 3.x.  Major new features and changes
in the 3.3 release series are:

* PEP 380, Syntax for Delegating to a Subgenerator ("yield from")
* PEP 393, Flexible String Representation (doing away with the
  distinction between "wide" and "narrow" Unicode builds)
* PEP 409, Suppressing Exception Context
* PEP 3151, Reworking the OS and IO exception hierarchy
* A C implementation of the "decimal" module, with up to 80x speedup
  for decimal-heavy applications
* The import system (__import__) is based on importlib by default
* The new "packaging" module, building upon the "distribute" and
  "distutils2" projects and deprecating "distutils"
* The new "lzma" module with LZMA/XZ support
* PEP 3155, Qualified name for classes and functions
* PEP 414, explicit Unicode literals to help with porting
* PEP 418, extended platform-independent clocks in the "time" module
* The new "faulthandler" module that helps diagnosing crashes
* A "collections.ChainMap" class for linking mappings to a single unit
* Wrappers for many more POSIX functions in the "os" and "signal"
  modules, as well as other useful functions such as "sendfile()"
* Hash randomization, introduced in earlier bugfix releases, is now
  switched on by default

For a more extensive list of changes in 3.3.0, see
