If you haven't tried it yet, please give the release candidate a try: http://download.wikimedia.org/mediawiki/1.18/mediawiki-1.18.0rc1.tar.gz

If you've tried it out and found a problem, please let us know.

But, if it works for you, please let us know that, too.

For example, I upgraded a MediaWiki site that I maintain from 1.15 to 1.18. Except for some trouble with the customized skin, things went smoothly.

I added my report to https://www.mediawiki.org/wiki/MediaWiki_roadmap/1.18/Installation_reports but it is looking pretty lonely right now. Please add your own experience.

Thanks,

Mark.
