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 3.4.6rc1 and Python 3.5.6rc1.

Python 3.4 is now in "security fixes only" mode.  This is the final 
stage of support for Python 3.4.  Python 3.4 now only receives security 
fixes, not bug fixes, and Python 3.4 releases are source code only--no 
more official binary installers will be produced.

Python 3.5 is still in active "bug fix" mode.  Python 3.5.3rc1 contains 
many incremental improvements over Python 3.5.2.

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 3.4.6rc1 here:


And you can find Python 3.5.3rc1 here:


Python 3.4.6 final and Python 3.5.3 final are both scheduled for release 
on January 16th, 2017.

Happy New Year,
