Timeline for python upgrade?

Python... currently at the end of the 3.6 series in Pro (aka, 3.6.10).

Various packages that are used in the ecosystem are about to begin retiring 3.6.x.

For example... numpy will be saying goodbye

NEP 29 - Dropping Python version support · Issue #66 · dask/community · GitHub 

and, IPython

ipython/version7.rst at master · ipython/ipython · GitHub 

jupyterlab and jupyterlab-server... are they next?

Adopt NEP 29 (timeline for which versions of Python to support) · Issue #8577 · jupyterlab/jupyterla... 

Lots have been added to python  3.8.5 Documentation ... the last stable release

(don't forget to go back and check the 3.7 branch and look forward to 3.9/3.10 coming branches)

Is ArcMap the reason for the holdback?

Given that major and minor releases control substantive changes...

Releases and patches—ArcGIS Pro | Documentation 

and minor change from 2.5 to 2.6 didn't produce a python change AND minor changes seem to occur once a year around UC, does that mean that we have to wait until next year?

Does anyone have any thoughts on this?

Kory Kramer‌ I will flag you and perhaps the comments on Beta 2 about python versions could be fleshed out here

Another downside for not upgrading to 3.8 at least.

I work extensively with numpy and want to use typing without having to install extra packages.  Current versions of numpy ( aka  >= 1.19 ) allow for numpy-based typing, however....

Typing (:mod:`numpy.typing`)
.. warning::
Some of the types in this module rely on features only present in
the standard library in Python 3.8 and greater. If you want to use
these types in earlier versions of Python, you should install the
typing-extensions_ package

from.... numpy/ at master · numpy/numpy · GitHub 

Not a biggie for most, but for those that think code documentation is as important as the code, this is becoming a limitation

I would still love to hear the reasons python versions lag.  Perhaps, it is time for streams of ArcGIS  Pro

Hello everybody,


Same thing happening to Python 3.7...


Numpy dropped support in december (NEP29:, and the drop is cascading among the community (xarray, pandas, ...)

Do you know when ArcGis Pro will support Python 3.8 or newer ?
