Status key¶
Python releases go through five phases, as described inPEP 602. Releasemanagers can adjust specific dates as needed.
- feature:
Before the first beta, the next full release can accept new features,bug fixes, and security fixes.
- prerelease:
After the first beta, no new features can go in, but feature fixes(including significant changes to new features), bug fixes, and security fixesare accepted for the upcoming feature release.
- bugfix:
Once a version has been fully released, bug fixes and security fixes areaccepted. New binaries are built and released roughly every two months. Thisphase is also calledmaintenance mode orstable release.
- security:
After two years (18 months for versions before 3.13), only securityfixes are accepted and no more binaries are released. New source-only versionscan be released as needed.
- end-of-life:
Five years after a release, support ends. The release cycle isfrozen; no further changes are allowed.
