Release 2023-01 follow-up #1181

release: May 21th

wanted:

• Python-3.11.2 (2023-02-06, 3.11.3=2023-04-03)
• jupyterlab-3.6.3 (Jupyterlab-4 is too fresh)
• pytorch-2 for python-3.11
• numba for python-3.11
• infrastructure:
  • simplify:
    • remove py3compat use
    • redirect "jupyter notebook" icon to "jupyter nbclassic" (that is no longer needed with Jupyterlab4)
    • trying to be utf-8 in console
  • modernize:
    • replace legacy RISE per jupyterlab_rise,
    • build winpython wheel via pyproject.toml: PEP 517, 518, 621, ...

focus:

• push the python eco-system envelop on: speed, multi-core, web:
  • per-interpreter GIL on Python-3.12. (PEP 684 – A Per-Interpreter GIL
  • NO-GIL on Python-3.12.0-a7 (PEP 703 – Making the GIL Optional )
  • multi-process on WASM Python-3.12 (as no shared-state between webworkers in WASM standard, yet)
  • PyPy "JIT" speed interest relies on a Hpy PEP (idea teased again at Python langage summit 2023), and catching-up in version for 3.13.
• reduce maintenance effort

exploratory:

• all these python-on-wasm competition for the next 10x growth of users : pyscript, jupyterlite, jupyterlite.github.io/xeus-python-demo/lab/index.html, shinylive.io

postponed:

• build winpython wheel out of make.py
• per interpreter GIL available only starting Python-3.12.0b1
• jupyterlab-4 + notebook 7 (bringing RISE equivalent)
• bokeh-3.2, Panel-1.0.1, Geoviews-1.10
• no appetite yet to re-include a branch with MKL wheels
