There's a new security bug in MediaWiki that's affecting all versions back to 1.7.x. Since I've been working on upgrading us to 1.9.x anyways, I decided to upgrade to 1.9.x instead of to the bug-patched version of 1.8.
I'm going to be upgrading our MediaWiki installation later this evening (sometime around 8PM EST). It should take less than a second to swap new files into place and possibly a minute or two to update the databases. Most users won't notice the db updates.
Let me know if you see anything strange after the upgrade. There are some neat new features in MW 1.9.x, and I've been waiting too long to get them installed. --Evan 13:35, 21 February 2007 (EST)
This upgrade is complete on all Wikitravel language versions. You can see the new version on Special:Version. I did a lot of testing on this upgrade, and I think I caught everything, but there's always something, so please contact me (en:User:Evan) if you see something strange or broken or unusual.
The RELEASE-NOTES may be interesting to some people. The two big changes I've noticed are the new "undo" functionality on diffs, which I think makes it easier to revert a page; and the count of characters changed in Special:Recentchanges. There are probably some other ones, but I haven't stumbled across them yet.
I was doing the database updates a few minutes ago, and if you tried to save an article during that time, you'd see an error saying that there was no 'redirect' table in the database. That should be fixed now; let me know if it's not. --Evan 22:19, 21 February 2007 (EST)
OK, came across a gross error where user's names were getting caught in the cache. I've reverted to 1.8.3 until I figure out what the problem is. --Evan 22:23, 21 February 2007 (EST)
I've reverted the revert. It seems to be working OK now. --Evan 23:23, 21 February 2007 (EST)
I'm seeing some weird behaviour around new message notifications. If you see new message notifications on any article pages (especially for someone who's not you!), please let me know. --Evan 00:41, 22 February 2007 (EST)
