Evaluate dropping 3.5

[ocelotl]

I was running some 3.5 tests this morning and I got this message:

DEPRECATION: Python 3.5 reached the end of its life on September 13th, 2020. Please upgrade your Python as Python 3.5 is no longer maintained. pip 21.0 will drop support for Python 3.5 in January 2021. pip 21.0 will remove support for this functionality.

We have already done this for 3.4, if I remember correctly it meant looking into how many of our users are using 3.5.

I suggest we follow the same process for 3.5 and evaluate if it would be possible to drop support for this version.

Can pypi tell us how many downloads were by a specific Python version?

[codeboten]

It does: https://pypistats.org/packages/opentelemetry-api

There's a small percentage of downloads for 3.5

[owais]

That seems low enough and given we are still not GA, I suppose we can justify dropping 3.5 with those numbers.

[ocelotl]

Well, seems like pytest has dropped support for 3.5 😅

@codeboten
Thoughts?

[codeboten]

if folks are in favour of it, we should drop it with fairly minimal number of downloads.

Let's vote! reply to this comment with 👍 to drop 3.5, 👎 to keep supporting it

[ocelotl]

@lzchen, @codeboten, @owais what do you think?

[lzchen]

Let's do it. Should probably do this before our release.

Drop! Drop! Drop!
