On behalf of the Python development team, I'm chuffed to announce the second alpha release 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 so far include:
- PEP 435, a standardized "enum" module
- 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 447, a new magic method for metaclasses (
__typelookup__
)- PEP 448, making automatic sequence unpacking more general
Those last two PEPs are still in draft form and not accepted nor have any committed code yet.
