Some of the test failures are fixed on reverting https://bugs.python.org/issue36996 . I am not sure if it's a CPython regression or if asynctest test's have to be changed as per the changes over patch can now act on async functions.

Any updates on that?

*** Bug 1736476 has been marked as a duplicate of this bug. ***

Looks like 0.13.0 builds and its testsuite passes, so I'll just bump the version.

... but rawhide is still carrying python 3.7.4?

Anyway, the bug title says FTBFS in F31, which is no longer true, so I'm closing this.

rawhide is still carrying python 3.7, yes. if it builds in rawhide, it's good. if it builds with 3.7 but not 3.8, I'll figure that out and open a separate bug if needed.

Thanks.

And indeed it fails: bz1739895
