On behalf of the Python development community and the Python 3.4 and 
Python 3.5 release teams, I'm relieved to announce the availability of 
Python 3.4.7rc1 and Python 3.5.4rc1.

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 3.5.4 will be the final 3.5 release in "bug fix" mode. After 
3.5.4 is released, Python 3.5 will also move into "security fixes mode".

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 3.4.7rc1 here:


And you can find Python 3.5.4rc1 here:


Python 3.4.7 final and Python 3.5.4 final are both scheduled for release 
on August 6th, 2017.

Happy Pythoning,
