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.
