This is a summary of recent technology and site configuration changes that affect the English Wikipedia. Note that not all changes described here are live as of press time; the English Wikipedia is currently running version 1.43.0-wmf.4 (2111e6d), and changes with a version number higher than that will not yet be active.

Fixed bugs

• Formulae entered with the <math> tag now no longer have a chance of line-breaking when rendered as HTML. ( r23649, bug 10438)
• An API query for a page's protection status now no longer has a chance of causing a database error and thus producing no useful output. ( r23636, bug 10439)
• Parameters 3 and 4 to MediaWiki:Movepage-moved can now be used inside wikilinks without problems. ( r23604, bug 10455)
• Watching pages no longer fails in Gecko-based browsers when the page's title contains a zero-width non-joiner character in the page's title. (Previously the watch appeared successful but failed anyway.) The same fix fixed the same error when using the CategoryTree feature. ( r23834, bug 10477)

New features

• An ( undo) link is now available for each edit on page histories, without going via the ( diff) link first. ( r23771, bug 1783)
• A new API query prop=imageinfo has been implemented, to query for details about an image. ( r23819, bug 9142)
• It's now possible to query the size of the database server replication lag, using an API query for meta=siteinfo. ( r23823, bug 10211)
• A local page MediaWiki:Spam-blacklist was added for blacklisting spam links from just one Wikimedia project. (Adding spam links to the Meta blacklist, m:Spam blacklist, will blacklist spam links from all Wikimedia projects.) ( r23849, bug 8492)

Configuration changes

• Adding an external link to http://en.wikiversity.org (or any other language-version of Wikiversity) no longer triggers a CAPTCHA for new and unregistered users. ( bug 10440)

Other technology news

• The Choctaw Wikipedia ( http://cho.wikipedia.org) has been closed. ( bug 10443, proposal on Meta)
• Wikipedia was uneditable for about an hour from 14:54 to 15:54 UTC on 3 July; the developers' log gives some possible reasons as to why ('brion' is User:Brion VIBBER): [1]

• 15:53 brion: lag problems on enwiki -- all slaves lagged (approx 3547 sec), but no apparent reason why
• 15:56 brion: lag problem resolved. stop/start slave got them running again; presumably the connections broke due to the net problems but it thought they were still alive, so didn't reconnect

Ongoing news

• 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.
