0.0.20.alpha4 prerelease

This is a short term release. I expect to remove this tag at some point after
I cut the next release. It is quite possible that the next release will not
be 0.0.20, as there are quite a few features that have been added since 0.0.19.

The commits between 0.0.19 on main and this commit are likely to be rewritten,
as this is not a finalized changeset.

I may drop features between now and the next release, but this is quite unlikely.

I expect to leave this release up for some period after the next official
release.

Note: this is the first release where I intend to use the ability to report
on the status of a release after it is made.
