Python 3.6.9rc1

Release Date: June 18, 2019

Python 3.6.9rc1 is a release candidate preview of the latest security fix release of Python 3.6.

Note

Python 3.7 is now released and is the latest feature release of Python 3. Get the latest release of 3.7.x here. Python 3.6.8 was the final bugfix release for 3.6.

Python 3.6 has now entered the security fix phase of its life cycle. Only security-related issues are accepted and addressed during this phase. We plan to provide security fixes for Python 3.6 as needed through 2021, five years following its initial release. Security fix releases are produced periodically as needed and only provided in source code form; binary installers are not provided.
