On behalf of the Python development community and the Python 3.4 and Python 3.5 release teams, I'm delighted to announce the availability of Python 3.4.6 and Python 3.5.3. 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 3.5.3 contains many incremental improvements over Python 3.5.2. There were literally no code changes between rc1 and final for either release. The only change--apart from the necessary updates from "rc1" to final--was a single copyright notice update for one of the OS X ".plist" property list files in 3.5.3 final. You can find Python 3.5.3 here: https://www.python.org/downloads/release/python-353/ And you can find Python 3.4.6 here: https://www.python.org/downloads/release/python-346/ Best wishes, //arry/
