myxwiki.org has been upgraded to XWiki 17.4.0. If you own a wiki hosted there, you should have a look at the release notes for this version.
Your wiki might not yet be fully upgraded, but it will eventually be, automatically in the background. It should still be usable in the meantime (some new features and improvements listed in the release note might just not yet be visible), but page save might be slower than usual while the upgrades are running.
Enjoy!
