Note: A newer bugfix release, 3.2.5, is currently available. Its use is recommended.
Python 3.2 was released on February 20th, 2011.
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 only few changes to 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
- a much improved ssl module with support for SSL contexts and certificate hostname matching
- a sysconfig module to access configuration information
- additions to the shutil module, among them archive file support
- many enhancements to configparser, among them mapping protocol support
- improvements to pdb, the Python debugger
- 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

|||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).|
|||(1, 2) There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here. Also, on Mac OS X 10.6, if you need to build C extension modules with the 32-bit-only Python installed, you will need Apple Xcode 3, not 4. The 64-bit/32-bit Python can use either Xcode 3 or Xcode 4.|
