release date: end june 2025

wanted:

• Spyder-6 defect resolved (needed package traitlets-5.14.3)
• Drag & Drop re-implemented on Spyder, IDLE, wppm (keeping anti-virus community happy)
• Python-3.13.5 (REPL bug fix), and a last Python-3.12 cycle
• the Weelhouse structure: (PEP-0751 evolution)
  • a "dot" version with a ./Wheelhouse/included.wheels directory of original pypi wheels (with same hash-256),
  • a lockfile to install from the provided Wheelhouse, or wppm -i them package per package
• simplify infrastructure and maintainance further:
  • ENDING: the changelog works also on WheelHouse, and in shipped WinPython
  • NAVIGATING: piptree can navigate in a Wheelhouse directory
  • DOS: remove 9 DOS scripts, remains 18

Explore:

• speed:
  • faster cpython-3.14 vs 3.13: 3%
  • JIT is in python-3.14.0b2: 0%
  • tail calling : 15%
  • free-threading: 2.5x on 4 threads, interesting pycon 2025 talk Building a NoGIL Load Balancer in 30 minutes - Alvaro Duran
  • multi-interpreter standard library will be in 3.14
  • RUST invasion: ruff, uv, ty or meta's pyrefly
• more IA use to improve and simplify the code, and learn-by-doing to prompt IA for less defects
• the 1 bit AI model from ms ...
• PEP 773 – A Python Installation Manager for Windows
• Wheel-Next initiative: https://wheelnext.dev/summits/2025_03/slidedecks_and_resources/
• can we fully evacuate from cmd.exe ? check what happens in cibuilds

Direction:

• Help Python Eco-system by favorising :
  • speed: latest cPython jit/multiple-interpreter, and AI-workload wanting free-threading
  • standard: dataframe API protocol, WheelNext
  • security: moving to lockfiles, signed wheels ... PEP-0751
  • browser (and WebApp): Jupyterlite compatible packages
• WinPython sustainability:
• make code simpler, smaller, AI-maintainable
• less x64 / DOS footprint (arm is coming)
• direction is an integrated or dowloadable set of standard signed wheels, a pylock.toml file
