DESCRIPTION:This talk is a follow-up to my EuroPython 2025 session on the f
 oundations of the CPython JIT compiler. It looks at how the JIT has evolve
 d since Python 3.14 and where it stands as Python 3.15 approaches release.
  We cover the transition of the JIT from an experimental feature towards a
  supported part of CPython\, how it fits into the runtime today\, and what
  that means in practice for users and distributors. The talk also explores
  how the JIT interacts with free-threaded builds\, the current status of i
 ntegration with external debuggers\, and how these constraints shape real-
 world usage. Finally\, we examine how the JIT performs today\, where it al
 ready delivers substantial speedups\, where it does not\, and what realist
 ic performance expectations look like for Python 3.15.

DESCRIPTION:Running Python natively on Windows on Arm requires more than a 
 working interpreter. To have the best developer experience\, it depends on
  compilers\, packaging\, binary wheels\, CI infrastructure\, and support f
 rom the wider library ecosystem.\n\nThis talk provides a status update of 
 the Python ecosystem on Windows on Arm in 2026\, based on ongoing collabor
 ation between the open-source community\, Microsoft\, and Arm. We will cov
 er CPython support\, packaging\, wheels\, tooling\, and CI availability\, 
 with a focus on what developers can realistically use today.\n\nUsing wide
 ly adopted libraries such as PyTorch as examples\, we will show how native
  Arm support is being enabled and creating better capabilities across the 
 ecosystem\, what remaining challenges projects face when supporting Window
 s on Arm.\n\nThe talk will also cover the developer and CI story enabled b
 y native Arm runners and Windows 11 Arm images on GitHub Actions\, and how
  this infrastructure lowers the barrier for projects to add and maintain W
 indows on Arm support.\n\nThe goal is to give a snapshot of the current st
 ate\, highlight the remaining gaps\, and explain how contributors and main
 tainers can participate to the ongoing effort.
