🐍 CPython Core Dev Sprint 2025 wrap:

~50 core devs (yes, Guido too) and invited guests hacking in Cambridge. JIT, free-threading, C-API, endless side discussions.

It's safe to say the best ideas start over coffee and a whiteboard with @python.org: community.arm.com/arm-communit...

CPython Core Dev Sprint 2025 event For one week, Arm’s Cambridge HQ became the heart of Python development. Contributors globally came together for the CPython Core Developer Sprint.

Last month the CPython Core Dev Sprint 2025 took place at Arm (@developer.arm.com) Cambridge. 🔧

I’ve just published a full write-up on what happened, what went into organising it, and what it means for Arm & the Python community.
