Python 3.14.5rc1 landed on May 4, 2026, marking the start of the release-candidate phase for the next patch in the 3.14 series. The RC allows downstream packagers and library authors to verify compatibility before the stable release, which typically follows within one to two weeks if no blockers surface. For backend developers on 3.14, this is the moment to run integration test suites against the candidate and file any regressions upstream. The previous patch, 3.14.4, shipped on April 7; given that release cadence, a stable 3.14.5 is expected by mid-May. No action is required for production deployments yet, but early testing on staging environments is encouraged.
