It's weekly code review update time! :) Some changes of note...
User preferences:
* (bug 505) Time zones can now be specified by location in user
preferences, avoiding the need to manually update for DST. Patch by Brad
Jorsch.
Web standards behavior:
* (bug 2585) HTTP 404 return code is now given for a page view if the
page does not exist, allowing spiders and link checkers to detect broken
links.
* (bug 16459) Use native getElementsByClassName where possible, for
better performance in modern browsers
Localization/UI changes:
* (bug 16612) Fixed "noprint" class for Modern skin print style

messages for clarity over "previous/next"
* (bug 16026) revision-info, revision-info-current, cannotdelete,
redirectedfrom, historywarning and difference messages now use Wiki text
rather than raw HTML markup
Upload/file-handling issues:
* (bug 13835) Fix rendering of {{filepath:Wiki.png|nowiki}}
* (bug 16772) Special:Upload now correctly rejects files with spaces in
the file extension (e.g. Foo. jpg).
API changes:
