We've gotten some feedback already -- https://github.com/SemanticMediaWiki/SemanticMediaWiki/issues/212 -- about the RC for MediaWiki 1.23 that Markus made last week. Hopefully we can get this issue addressed in time for SMW users.
Are there any other issues that people have run into that we should know about before we do attempt to make a final release of 1.23?
If you've tried the RC and not run into any problems, that would be good to know, as well.
Thanks,
Mark.
