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.4 (a8dd895), 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.

• The API now correctly outputs errors in JSON if that was the output format requested. (r37349, bug 14758)
• It is no longer possible to move an image to an invalid title. (r37474, bug 14772)

• It is now possible to patrol new pages via the enhanced recent changes interface. (bug 5502http://bugzilla.wikimedia.org/show_bug.cgi?id=5502)
• It is now possible for bureaucrats to rename a user to a name already taken in the Single User Login system, as long as the global account and the local account have the same email address or password. (r37422, bug 13507)
• It's now possible to specify a number of entries to show in the RSS feed for a page history using the limit= URL parameter. (r37699, bug 14778)

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