Release 2022-03 follow-up #1085

release: october 2022

Wanted:

• Infrastructure:
  • cpython-3.10.6
  • cpython-3.11.0 (10% to 25% speed-up vs 3.10 on interactive Python applications)
  • github as a full secondary download site
  • no more MKL with pypi, for now, because:
    • loss of cgohlke site
    • no failover found.

Focus:

• python-3.11.0 stack debuging:
  • patch patsy
• infrastructure work:
  • re-implement pipdeptree into wppm, proof-of-concept in docs as a notebook
• more arrow/rust/wasm, less PyPy/mkl

Postpone:

• move away from setup.py https://setuptools.pypa.io/en/latest/userguide/quickstart.html#transitioning-from-setup-py-to-setup-cfg (requires change in build system)
• PyPy-3.9 (loss of Christoph Gohlke wheels)

Hopes/Wishes for 2022/2023:

• Python speed-up movement:
  • per-thread GIL: Shannon plan for 3.12
  • no GIL: Sam Gross pep for 3.13
  • c-extensions: a PEP for Hpy c-interfacing
• Python ubiquity movement:
  • WASM initiatives (pyodide/pyscript.net/jupyterlite)
• micromamba option
