Although there are several interesting patch series in progress, I think
there are enough useful new features in master that we ought to have
another release.

I plan to have a feature freeze starting on September 26 with a release
roughly a week later. After September 26 I'll only take bug fixes and
NEWS updates onto the release branch.

As usual, feel free to tag suggestions for the next release as
notmuch::0.23 in nmbug.
