Release Date: Feb. 9, 2014
Note: A newer bugfix release, 3.3.5, is currently available. Its use is recommended.
Python 3.3.4 was released on February 9th, 2014. This release fixes several security and a lot of overall bug fixes found in Python 3.3.3.
This release fully supports OS X 10.9 Mavericks. In particular, this release fixes an issue that could cause previous versions of Python to crash when typing in interactive mode on OS X 10.9.
Major new features of the 3.3 series, compared to 3.2

- 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)
- 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 "ipaddress" module
- The "sys.implementation" attribute

|||The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).|
