The release we pushed a few days ago was never announced, but I've
just updated the changelog to reflect the few minor fixes it
contained.
See the October 26 update:

Note, there is still a pending release which I'll document and
announce within the next 24-48 hours. This post is primarily to
inform you of the last release for which no standard announcement was
made.
