- Python 3.14.0 b4, the final beta of the upcoming Python 3.14 release, has been made available for download. The release is feature‑complete but still a preview; production use is discouraged. Core developers and third‑party maintainers are urged to test the new version and report bugs before the first release candidate on 22 July 2025. Key additions include free‑threaded support (PEP 779), deferred type‑annotation evaluation (PEP 649), template string literals (PEP 750), and a new Zstandard compression module (PEP 784). The beta also introduces a zero‑overhead debugger interface (PEP 768) and improved error messages.
