Release Date: march may 2022 ... aka Spyder "au naturel"

Wanted:

• Infrastructure:
  • a full WinPython-3.10: with all usual packages
  • Jupyterlab-3.3 (Jupyterlab-4 api breakages will need time to be digested)
  • PyQt5-5.15 to replace PySide2-5.15.2.1 in Python-3.10, so Spyder updates are becoming "natural",
  • Python-3.10.4, Python-3.11.0 alpha 6
  • PyPy-3.8 (PyPy-3.9 may not be mature enough to receive interesting wheels)
  • NEW: a BLAS variant that removes numpy-MKL and Torch, to be 200 Mo ligther at download
• major modules:
  • SciPy-1.8.0
  • Spyder-5.3.0 (has PyQt5-5.15 official compatibility, PySide6 compatibility still not there)
  • late packages for python-3.10:
    • Torch-1.11.0
  • late fundamental packages for PyPy:
    • Pyside6-6.3 for PyPy-3.8 3.9

Focus:

• get Spyder updating with WinPython-3.10 from pip (so PyQt5-5.15 for now)
• helping PyPy catch-up effort in Python version and PySide6 integration,

Postponed:

• Numba-0.56 if in time (to support Numpy-1.22, Numpy-1.22 brings preliminary version of "Array-API" standard)

Hopes/Wishes for 2022:

• swarm of Python speed-up efforts brings results: Microsoft Shannon Plan, PyPy Hpy, Meta Nogil, Oracle GraalPython, Pyjion
• conventions (or Pep, or tweaks) helps writing Python Code JIT and multi-thread "10x boost" ready
• PyPy-3.9 in Q2 2022, PyPy-3.10 in Q4 2022
• Spyder can run on PySide6
• push to Data-API to get problematic packages (Numba, Torch, Tensorflow) sooner
