Python 3.14 beta 3 is now available, marking the third of four planned beta releases. This beta aims to facilitate community testing of new features and bug fixes before the final release, encouraging third-party maintainers to evaluate their projects for compatibility. The release is in development, and while nearing feature-completeness, modifications or deletions to features are still possible. Important new features in this release include PEPs 734 and 779, and developers are advised to await the official release candidate before implementing production changes.
This preview includes a number of new features designed to enhance the Python experience, emphasizing community testing and potential bug reporting during the beta phase.
Maintainers are encouraged to test their third-party projects with this beta release to ensure compatibility ahead of the full release, minimizing disruption in production environments.
