Python 3.14.0rc3 is go!

It’s 🪄 finally 🪄 the final 3.14 release candidate! https://www.python.org/downloads/release/python-3140rc3/ Note: It’s another magic release. We fixed another bug that required bumping the magic number stored in Python bytecode ( .pyc ) files. This means file .pyc files created for rc2 cannot be used for rc3, and they’ll be recompiled. The ABI isn’t changing. Wheels built for rc1 should be fine for rc2, rc3 and 3.14.x, so this shouldn’t affect too many people. This release, 3.14.0rc3 , is the final release preview. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release. The next release of Python 3.14 will be the final release, 3.14.0, scheduled for Tuesday, 2025-10-07. There will be no ABI changes from this point forward in the 3.14 series, and the goal is that there will be as few code changes as possible. Call to action We strongly encourage maintainers of third-party Python projects
