There are now many more translations for language names. 
Software changes this week
The new version of MediaWiki (1.25wmf1) is on test wikis and MediaWiki.org since September 25. It will be on non-Wikipedia wikis on September 30, and on all Wikipedias on October 2 (calendar).
Errors from Scribunto (Lua) are now shown on the page. Before, you had to click on "Script error" to see them. 
You can add an "autovalue" for a field in TemplateData. When users add the template to a page, the value will be added automatically. An example is when a clean-up template shows the date it was added. 
If you change a user preference but don't save it, it now asks if you want to save it. 
The PDF export tool has changed. The new one has better language support but it doesn't offer ZIM and EPUB formats. 
Hi there! I thought you might be interested in WikiProject Wikify's October Wikification Backlog Elimination Drive. We'll be trying to reduce the backlog size by hundreds of articles and we need your help! Hard-working participants in the drive will receive awards for their contributions. If you have a spare moment, please join and wikify an article or tell your friends. Thanks!
Note: The drive starts October 1, but you can still sign up!
