Just released: Python 3.14.0 release candidate 2! 🚀🐍

🪄 This was planned for 2025-08-26, but we fixed a bug that required bumping the magic number stored in bytecode (.pyc) files

🪄 This means .pyc files created for rc1 will be recompiled for rc2

🪄 The ABI isn’t changing

🪄 Wheels built for rc1 should be fine for rc2, rc3 and 3.14.x

🤖 Did I mention Android binaries?

🏆 Bonus: We also released an early Python 3.13.7!
