Internet Explorer 6 and 7 are no longer supported. This means the browsers might start looking a bit weird. They will not get security support. You can't read Wikimedia wikis in Internet Explorer on Windows XP or Windows versions that are older than Windows XP. This is because almost no one uses the browsers anymore. Supporting them made the wikis less secure for everyone else. 
In the future section headings might have a share link. This is to make it easier to link to the section. You can read more and discuss.

There is a translation tool we use on wikis with more than one language. For a few days it did not create pages for new languages when someone translated a page. The languages did not show in the language bar. This has been fixed. 
The history and diffs can show wrong content. This is because of a cache problem. It will soon be fixed.
