This page covers changes to the MediaWiki software and English Wikipedia site configuration, and other technology news, since the last technology report (on 9 April 2007). Bugfixes and new features that do not affect the English Wikipedia have been omitted from this.

• A new special page Special:Withoutinterwiki was added, that displays pages with no interwiki links. (bug 5820)

• Several improvements were made to the query.php and api.php APIs:
  • A new query to find out the edit count of a user, according to the server's internally stored edit count data, was added. (r22095)

• The 'border' keyword, which is used the same way as 'thumb' and 'frame', was added to image markup to give a new way to format an image. (r22358, bug 6072)
• New keywords for specifying spacing when symbols are being used in an unusual manner (such as \mathord) were added to the <math> tag markup. (r22478, bug 7993)

• 'Tidy', which fixes the generated HTML from Wikipedia pages, has been upgraded; wikitext will now render differently in some cases to how it rendered before, [1] and such wikitext will need to be changed.
• It's now possible to use escaped forms of &rlm; (a right-to-left mark) written in right-to-left text (so as to cause the text to go right-to-left in the edit box too): ‏&רלמ;‏ and ‏&ررلم;‏ are now enabled on Wikimedia wikis. (Left-to-right marks should still be written in English as usual.) [2]
• User accounts where the password and username were equal can no longer log in. Such users will need to reset their password via email; if no email was provided, then only a developer can restore access to the account.
• It's now possible to transwiki pages from the English Wikipedia to Meta, with the help of a Meta admin. (bug 8557)
• A Table: namespace was created, after discussion at Wikipedia:Proposal for intuitive table editor and namespace and bug 2194, but it had no special properties. After more discussion, it was removed again. All pages that were in that namespace were moved into a pseudonamespace at the time, and now currently reside either in the Template: namespace or User: namespace.
• A hexadecimal number beginning "09 F9" was added to the spam blacklist to prevent it being spammed into articles. It has since been removed from the blacklist. [3]
• Use of the <source> tag (the Highlight extension), which places syntax highlighting on a sample of code, has been enabled. (bugzilla:7163) (Further changes were made to this feature: currently it doesn't link keywords (r22240, bug 9995), and the styling used was made customizable by editing MediaWiki:Geshi.css (r22308, bug 9951).)
• Non-autoconfirmed users can now reupload over files they uploaded themselves. (r21943, bug 5057)

• A read-only WAP version of Wikipedia has been set up at http://en.wap.wikipedia.org.
• A new version of the search feature is being tested at http://ls2.wikimedia.org/ (loaded with some old English Wikipedia search data for testing); feedback would be appreciated.
• Several new Wikimedia wikis were created (Kabyle Wikipedia, Italian Wikiversity, Hakka Wikipedia) and two were closed (Kanuri Wikipedia and Low Saxon Wikiquote).

• 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.
• Lists of redirects and new default names (possibly even containing spaces) for the Special: namespace are being sought, even for English-language projects; please post any suggestions you might have on mw:Special page names.
