The 32-bit targets arm-linux-androideabi and i686-linux-android are not tier 3 supported platforms, but will have best-effort support.

LGTM thanks, I'll merge after the next release as we will probably drop Python 3.8

[cclauss]

Why test after making a release? Usually, tests are added before making a release.

[AndreMiras]

In this PR you dropped 3.8 which is a good thing, but that means we officially drop the support for it (which we want to).
However I want to tag a release before we drop the support, so that the tagged release would be the last supporting 3.8

[cclauss]

Please let me know if we should bring Py38 back in.

Nope it's perfect keep it this way, I want to make a release in the coming weeks

[cclauss]

The reason stated for sitting on this was that it remove the EOL Python 3.8 so let's put it back is so that we are running tests on Python 3.8 plus all currently supported versions of CPython.
