This is a summary of recent technology and site configuration changes that affect the English Wikipedia. Note that not all changes described here are necessarily live as of press time; the English Wikipedia is currently running version 1.44.0-wmf.3 (b4aac1f), and changes to the software with a version number higher than that will not yet be active. Configuration changes and changes to interface messages, however, become active immediately.

• Special:CategoryTree now no longer accidentally confuses non-category pages with categories with the same name. (r25920, bug 11383)

• The page history now has a different <title> from the page itself, so that they can be distinguished in browser histories; administrators can customize this via MediaWiki:History-title. (r25952, bug 11151)
• When a <ref> tag has no content and no tag with the same name to copy the content from, it now displays an obvious error message rather than a blank reference. (r26045, bug 11426)

• After an unusually heated debate, the Siberian Wikipedia (http://ru-sib.wikipedia.org) was closed; for more information, see m:Proposals for closing projects/Closure of Siberian Wikipedia and bug 11397.

• Internationalisation has been continuing as normal; help is always appreciated! See m:Localization statistics for how complete the translations of languages you know are, and post any updates to bugzilla or use Betawiki.
