It does not make much sense to put this on master, as the popat! has been added in Julia 1.5 and Compat master requires Julia 1.6 now. But I'm fine with directly adding it to the release-3 branch. Let me try to change the PR accordingly...

[martinholters]

Took the liberty to rebase the branch accordingly and fix the README a bit, please double-check.

Right - makes sense.

Thank you for rebasing - all looks good.

@nalimilan - OK to merge and make a release?

@martinholters Can we just tag a 3.45.0?

Sure, that was the idea of bumping the version in this PR.
