Hi all,

Here is the First Release of WinPython-3.8, ending 7 month of developpement.


From a 3.7 version, you will :
- miss Tensorflow and PyTorch (no release available yet)
- benefit a one line  hack on Tornado to allow current Jupyter stack to work, until official support shows up in Q1 2020 (jupyterlab-2.0), see below. 
- a first push micro-service/ASGI stack (Flask-restPLus / Quart / Unicorn / Hypercorn) ... is added, inspired from :
   


- New Packages: 
   - FastAPI, uvicorn, Quart
   - datasette, python_language_server
- Upgraded Packages: 
  . numpy-1.17.3, pandas-0.25.2
- Variation per Version:
  . the cod version contains also a "portable VSCode" (that can be copied to other versions)

Areas of particular interest for testers:
- relevance or missings of packages choosen in ASGI stack, as this is an addition of coming cycle
- There is a hack to make Jupyter  work on Python-3.8, as the Official support seems only for v2.0. To make it work, you'll need to replay this hack on Tornado if you upgrade Tornado: https://github.com/tornadoweb/tornado/issues/2608#issuecomment-491489432

There are some signs of intent to accelerate Python release rythm https://discuss.python.org/t/pep-605-a-rolling-feature-release-stream-for-cpython/2418
Reducing the time from release to [Full] Distribution availability shall be part of the effort.

nota 2019-10-21: for unknown reason, the Tornado patch didn't apply on Winpython-3.8.0.0rc1 build . so you have to apply it by hand once: 
- start winpython command prompt 
- launch 

%WINPYDIR%\python.exe -c "from winpython.utils import patch_sourcefile;patch_sourcefile(r'%WINPYDIR%\Lib\site-packages\tornado\platform\asyncio.py', 'import asyncio', 'import asyncio;asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())  # python-3.8.0' )"

Hi all,

Final re-spin of WinPython-3.8.0.0rc is out,


Change:
- a re-factoring of the build process was necessary to solve the build problem of initial rc (https://github.com/winpython/winpython/issues/789)
- the "cod" version now includes the updated python-vscode extension of 2019-10-23 (patch release)
