For more information, see our page on Python Support.
Of note, the build process for this release includes a number of improvements (first introduced with last month’s Python 3.9.13 release) that reduce the size of the Python runtime included in application slugs by 75%, freeing up more space for application dependencies and other assets. For more details, see the Python buildpack changelog.
