On behalf of the Python development team, I'm delighted to announce
the first release candidate of Python 3.4.
This is a preview release, and its use is not recommended for
production settings.
Python 3.4 includes a range of improvements of the 3.x series, including
hundreds of small improvements and bug fixes. Major new features and
changes in the 3.4 release series include:
* PEP 428, a "pathlib" module providing object-oriented filesystem paths
* 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
* PEP 445, a new C API for implementing custom memory allocators
* PEP 446, changing file descriptors to not be inherited by default
in subprocesses
* PEP 450, a new "statistics" module
* PEP 451, standardizing module metadata for Python's module import system
* PEP 453, a bundled installer for the *pip* package manager
* PEP 454, a new "tracemalloc" module for tracing Python memory allocations
* PEP 456, a new hash algorithm for Python strings and binary data
* PEP 3154, a new and improved protocol for pickled objects
* PEP 3156, a new "asyncio" module, a new framework for asynchronous I/O
Python 3.4 is now in "feature freeze", meaning that no new features will be
added. The final release is projected for mid-March 2014.
