release 2021-01 follow-up #908

Release Date: early march 2021

Wanted:

• a full stable Python-3.9 stack vs Python-3.8:
  • rc version: numba,
  • released version: pytorch, pyarrow, onnx
• Jupyterlab-3.0.1 or more
• all plugins tweaked to jupyterlab-3:
  • bqplot, ipyleaflet, dask_jupyterlab, ipympl, ipycanvas
  • not this cycle: jupyter_bokeh
• Python-3.8.8, Python-3.9.2 (february 15th....)

Focus:

• winpython simplification:
  • remove Jupyterlab-2 bloat
  • simplify packages.ini manual update
  • allow more icons to open on the directory of the Drag&Drop file
• closely follow pip-21.0dev
• pushing on WASM, Integrated ML :
  • wasmer
  • next time: onnx/windows integrated ML / Pytorch Fastai
• follow Python-3.10.0 alpha series

non-focus:

• Qt-6 / PySide6 (basic) compatibility
• PySide2: waiting Spyder & Pyzo compatibility, for non-regression in features

Question:

• shall Classic Notebook go away ?
  • jupyter team answer is yes, but undefined timeline
  • .... switched to "jupyter-nbclassic" at Release Candidate step.

Hopes/Wishes for 2021:

• nodejs no longer necessary to Jupyterlab-3, to see for WASM and VSCode.
• SQLite inside Python gets more features (math functions, stddev, multi-interpreter compatibility,...)
• Python-3.10 (hopefully) simplifies Asyncio/Trio thinking with PEP 654
• Python-3.10 simplifies multi-core, and pypy compatibility
• a solution to create launcher icons without NSIS (shimmy didn't arrive there).
• a focus on OpenAPI (ex-swagger) and GraphQL from Facebook and gRPC from Google
