I'm sorry a lot of these have been held up for a while; we've been mainly working on stabilizing the wikis under the new server setup and preparing to put out a new release of the MediaWiki software with all the latest fixes and features -- for which of course we'll want the latest language files included.
My old todo list page has gotten rather unwieldy and out of date, I'm afraid, and it's hard to tell what's been done, what hasn't, etc. It would be a big help if people could put the relevant information onto these new wiki pages (currently empty):
http://meta.wikipedia.org/wiki/Complete_list_of_language_names All the suggestions for native language names that have been posted separately recently.
http://meta.wikipedia.org/wiki/Language_files_to_be_updated Please link to the exact wiki page that contains the updated file, or attach an update and send it to this list and say which was sent. If possible, please compare against the version of the file in CVS: http://cvs.sourceforge.net/viewcvs.py/wikipedia/phase3/languages/ and ensure that anything that got updated separately in CVS is also in your version.
http://meta.wikipedia.org/wiki/Other_language_bugs Any other bugs or problems that are specific to one of the languages/wikis: missing or corrupted messages, logo updates, sysops, etc.
Hopefully we can get these things cleared up in the next few days...
