On behalf of the Python development team, I'm happy to announce the first 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 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 * 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 * The new "faulthandler" module that helps diagnosing crashes * Wrappers for many more POSIX functions in the "os" and "signal" modules, as well as other useful functions such as "sendfile()" For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html The 3.3 whatsnews page doesn't seem to mention PEP 414 or Unicode literals at all.
