As of Thu Oct 20 19:13:20 UTC, 2022, Ubuntu 22.10 has been released and posts about it are no longer off-topic purely for being about 22.10 (of course, posts still should meet all the other criteria as described in the help center).
This does not mean that questions posted before the release that were closed for being about 22.10 should be re-opened. They may be re-opened on a case-by-case basis, but not generally. If you have a question you feel should be re-opened, propose it should be re-opened on Meta Ask Ubuntu (i.e., this site).
Also note that as mentioned in the release-notes (toward the bottom of that page), Ubuntu Unity is an official flavor.
