Python 3.4.5rc1

Release Date: 2016-06-13

Python 3.4.5rc1 was released on June 12th, 2016.

Python 3.4 has now entered "security fixes only" mode, and as such the only improvements between Python 3.4.4 and Python 3.4.5rc1 are security fixes. Also, Python 3.4 will only be released in source code form; no more official binary installers will be released.

  • PEP 435, a standardized "enum" module
  • PEP 436, a build enhancement that will help generate introspection information for builtins
  • PEP 442, improved semantics for object finalization
  • PEP 443, adding single-dispatch generic functions to the standard library

Notes on this release:

  • The OS X installers are now distributed as signed installer package files compatible with the OS X Gatekeeper security feature.
  • The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".) They will not work on Intel Itanium Processors (formerly "IA-64").
