What's new in this version:
- syntax for delegating to a subgenerator (yield from)
- flexible string representation (doing away with the distinction between "wide" and "narrow" Unicode builds)
- A C implementation of the "decimal" module, with up to 120x speedup for decimal-heavy applications
- The import system (__import__) is based on importlib by default
- The new "lzma" module with LZMA/XZ support
- a Python launcher for Windows
- virtual environment support in core
- namespace package support
- reworking the OS and IO exception hierarchy
- qualified name for classes and functions
- suppressing exception context
- explicit Unicode literals to help with porting
- extended platform-independent clocks in the "time" module
- a new key-sharing dictionary implementation that significantly saves memory for object-oriented code
- the function-signature object
- The new "faulthandler" module that helps diagnosing crashes
- The new "unittest.mock" module
- The new "ipaddress" module
- The "sys.implementation" attribute
- A policy framework for the email package, with a provisional (see PEP 411) policy that adds much improved unicode support for email header parsing
- 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

What's new in this version:
Core and Builtins:
- sys.platform is now always 'linux2' on Linux, even if Python is compiled on Linux 3.
- Accept bytes for the AST string type. This is temporary until a proper fix in 3.3.
Library:
- The distutils commands bdist_dumb, bdist_wininst and bdist_msi now respect a --skip-build option given to bdist.
- Fix crash in zlib module due to version mismatch.
Extension Modules:
- Fix a crash when ctypes.create_string_buffer(0) was passed to some functions like file.write().
