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.

Yay!!
Question: Now that we are in the RC phases, only critical bug fixes are allowed?
Only critical fixes go into the next RC, yes (I don't know when Larry is going to branch 3.4). Further, every such patch must be reviewed by at least two committers[*] (which may include the submitter), and signed off on by the release manager.
Of course, what counts as "critical" sometimes gets debated :)

[*] this is what the "commit review" stage is really for.
Hi,
It would be nice to give also the link to the whole changelog in your emails and on the website: http://docs.python.org/3.4/whatsnew/changelog.html
Congrats for your RC1 release :-) It's always hard to make developers stop addings "new minor" changes before the final version :-)
