Python 3.15.0 Beta 1 released
Python 3.15 beta 1 just landed as the first feature freeze preview, dropping explicit lazy imports, frozen dictionaries, and a centralized profiling package that actually makes debugging slower scripts bearable. The JIT compiler now pulls an eight to thirteen percent speed boost across major platforms, while Windows binaries finally switch to the tail-calling interpreter by default so you stop fighting legacy performance quirks. Core developers are actively pushing third party maintainers to break things early since ABI stability is still being locked down before the August 2026 release candidate phase. Regular users should keep their production servers on stable builds and only test this beta in isolated environments until the final version ships next year.
