The release of Python 3.14.0b2 marks the second beta version in the development of Python 3.14, allowing the community to test new features and identify bugs. While it aims to be feature-complete, changes may still occur prior to the release candidate phase. Developers are urged to report any issues found during testing. Key updates include the transition from PGP signatures to Sigstore for verifications, the introduction of an experimental JIT compiler, and advice against using this beta version for production applications.
Beta 3.14.0b2 is a release preview of Python 3.14, encouraging testing of new features while cautioning against use in production environments.
We strongly encourage maintainers of third-party Python projects to test with 3.14 during the beta phase and report issues.
While the release is planned to be feature-complete entering the beta phase, modifications or deletions may occur up until the release candidate phase.
Major changes include the removal of PGP signatures for release artifacts, with Sigstore recommended for verifiers, and introduction of an experimental JIT compiler.
