On behalf of the Python development community and the Python 3.4 and Python 3.5 release teams, I'm pleased to announce the availability of Python 3.4.5rc1 and Python 3.5.2rc1.

Python 3.4 is now in "security fixes only" mode. This is the final stage of support for Python 3.4. All changes made to Python 3.4 since Python 3.4.4 should be security fixes only; conventional bug fixes are not accepted. Also, Python 3.4.5rc1 and all future releases of Python 3.4 will only be released as source code--no official binary installers will be produced.

Python 3.5 is still in active "bug fix" mode. Python 3.5.2rc1 contains many incremental improvements over Python 3.5.1.

Both these releases are "release candidates". They should not be considered the final releases, although the final releases should contain only minor differences. Python users are encouraged to test with these releases and report any problems they encounter.

You can find Python 3.4.5rc1 here:

https://www.python.org/downloads/release/python-345rc1/

And you can find Python 3.5.2rc1 here:

https://www.python.org/downloads/release/python-352rc1/ 

Python 3.4.5 final and Python 3.5.2 final are both scheduled for release on June 26th, 2016.

Happy Pythoneering,
