The Short Version

Official Python records confirm October 2, 2023, as the release date of Python 3.12.0, the first final release in the 3.12 series. Release documentation, schedules, download records, file timestamps, and contemporaneous announcements consistently support that date.

Caveats

  • “Python 3.12” refers here to the initial final release, version 3.12.0; later 3.12 maintenance versions have different release dates.
  • Some announcement pages show October 1 metadata, likely reflecting timezone or publication settings rather than the official release date.
