• <imagemap> can now contain 'anchor' links to a section of an article. (r21299, bug 8917)
• Redirects are now shown in categories; their appearance can be (and has been) customized to be different from non-redirect entries. (r22156)
• Diff displays are now correctly balanced. (r22204, bug 1229). (The method used to balance it was later updated for some browsers; Internet Explorer 6 and above and Safari will cause long lines to break, Gecko, Firefox and Opera will show scrollbars. (r22227, bug 1438))
• A new special page Special:Withoutinterwiki was added, that displays pages with no interwiki links. (bug 5820)
• When Special:Contributions and/or Special:Watchlist are lagged, a message displays showing how bad the lag is. (r22242, bug 9628)
• 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)
  • Old revisions can now be returned using the 'revid' parameter. (r22249, bug 9938)

• 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.

Volunteers at the English Wikipedia and SOS Children UK have today launched the Wikipedia Selection for Schools. The Selection is about the size of a 15 volume encyclopaedia, with 24,000 pictures, 14 million words and articles on 4625 topics. It includes the best of Wikipedia, and many thousands of pages of extra material specifically selected to be of interest to children who follow the UK National Curriculum and similar curricula elsewhere in the world.

• The selection is organised around National Curriculum subjects
• The articles have been cleaned up and checked for suitability for children
• Website: Schools-Wikipedia.org
• Downloads: [4]
• Available for free as BitTorrent download (3.5GB with full size images) standard download, 1GB with only thumbnail images) or on DVD from the charity's offices in Cambridge.

There has been recent public discussion on the suitability of Wikipedia for UK schools. Many articles on the live Wikipedia website are of acceptable accuracy. This Selection aims to correct the remaining criticisms made of Wikipedia as a school resource:

• the Selection has been screened;
• the Selection cannot be vandalized;
• children cannot meet adults there;
• there are no very explicit articles or content. (The most explicit article is Birth control, which has been kept technical and neutral).

Florence Devouard, chair of the Wikimedia Foundation, said: "The Wikimedia Foundation aims to encourage the development and distribution of reference content to the public free of charge: this project is an excellent example of free resources being offered to a particular audience which we warmly encourage, and are proud to support."

Dr. Andrew Cates, CEO of SOS Children (and himself a Wikipedia administrator) said: "Wikipedia offers a fantastic learning resource. We are delighted to have been able to play a part in increasing the number of children who will be able to benefit from it. We are indebted to the volunteers in our offices and on Wikipedia who helped check articles and to the Wikipedia community for their help with this project."

The Selection can easily be run on school intranets or in remote locations in the developing world where Internet access is a problem. A pilot version of this release has already been distributed to schools in South Africa by the Shuttleworth Foundation. It is intended to extend and update the Selection periodically.

Just a few days after the death of Norwegian journalist Tron Øgrim (see related story), a Belarusian editor passed away this week. Uladzimir Katkouski, a well-known and award-winning Belarusian blogger who also made more than 1,300 edits to the English Wikipedia and nearly 900 edits to the Normative Belarusian Wikipedia between 2004 and 2006 as User:Rydel, passed away on May 26, 2007. Katkouski mostly edited articles about Belarus; among the articles he edited were Orsha, White Russia, and Belarusian language. He was evidently hit by a fire truck, and died after being in a coma.

Wikipedia reached the 3-month Alexa rank of 9 this week, passing Tencent QQ, the website of a Chinese instant-messaging program. Wikipedia generally hovers at rank 9 on most days, falling to rank 10 or 11 on Fridays and Saturdays. Wikipedia still has a long way to go to pass the number 8 site, Orkut; on only one occasion, in February, has Wikipedia reached a daily rank of 8; this rise was probably due to the Chinese New Year, as this usually produces spikes in Wikipedia's ranking, as traffic to the main Chinese-language sites falls sharply at this time each year.

Notably, Alexa statistics also show that about 6.3% of internet users visit Wikipedia, and that as of late, Wikipedia accounts for nearly 0.5% of internet traffic, about 1 in 200 page views. Additionally, Wikipedia reaches more users than Orkut, 7th-ranked Baidu, and 6th-ranked MySpace; however, Wikipedia ranks lower due to the low number of pages visited by each user (5.0) compared to the other sites (38.7, 12.5, and 37.0, respectively).

Jimbo Wales appeared on The Colbert Report, a satirical television program hosted by comedian Stephen Colbert. Stephen's character of the same name interviewed Wales, talking about the project and joking about a previous segment of the show where Colbert encouraged viewers to edit articles to state "the number of elephants has tripled in the last six months." (see archived story). Colbert again encouraged various vandalous additions, including the phrase "librarians are hiding something". After a comment by Colbert's character that Spanish users should learn English, Wales joked that he'd have to protect the entire Spanish Wikipedia. The full interview can be seen at Comedy Central here.

The volunteers who will serve on the Board Election Steering Committee for the upcoming Board of Trustees election were announced by Wikimedia Volunteer Coordinator Cary Bass. They include Aphaia and Jon Harald Søby, both of whom were election officials last year, along with Tim Starling as technical adviser. Joining the group this year are Benjamin Mako Hill, Newyorkbrad, and Philippe Beaudette.

The Arbitration Committee did not accept any new cases this week, and closed two cases. Acceptance of the controversial Badlydrawnjeff case regarding WP:BLP and related issues currently stands at 6/3/1/0.

The committee is also considering whether to lift Dmcdevit's ban on Koavf (talk · contribs), and instead to impose probation and a revert parole, without a full hearing. Currently, voting stands at 5/0/0/1, but some editors have expressed concerns over whether it is appropriate to deal with the case by summary motion.

• Tobias Conradi: A case involving the actions of Tobias Conradi (talk · contribs) who, while acknowledged as a productive contributor, had been called incivil on various occasions. As a result of the case, he was placed on civility parole and revert parole.

• Henrygb: A case filed by David Gerard alleging that administrator Henrygb (talk · contribs) had used sockpuppets disruptively. As a result of the case, Henrygb was desysopped, limited to one account, and banned from Wikipedia until he addresses the committee's concerns.

• PalestineRemembered: A case involving the actions of PalestineRemembered (talk · contribs), referred from the Community sanction noticeboard.

• Miskin: A case involving the actions of Miskin (talk · contribs), who was controversially blocked by Swatjester (talk · contribs · blocks · protections · deletions · page moves · rights · RfA) for one month (later reduced to one week) for revert warring.

• Abu badali: A case alleging that Abu badali (talk · contribs) has disruptively tagged non-free images for deletion, even when a valid fair-use justification exists, and has harassed editors who have complained about this behavior. Abu badali denies the allegations.

• NYScholar: A case involving the actions of a number of users, including NYScholar (talk · contribs) and Notmyrealname (talk · contribs), in relation to the Lewis Libby article.

• Piotrus: A case involving administrator Piotrus (talk · contribs) and other editors on Central and Eastern Europe-related articles. Multiple parties accuse others of edit warring, incivility, unethical behavior and biased editing. (An earlier arbitration case, Piotrus-Ghirla, was dismissed without prejudice in part due to inactivity of Ghirlandajo (talk · contribs), who was listed as a party in the new case.)

• Paranormal: A case involving the actions of various users, especially as regards bias and attribution, on "articles on paranormal and pseudoscientific topics", such as parapsychology and Electronic voice phenomenon.

• Hkelkar 2: A case involving the actions of Rama's Arrow (talk · contribs · blocks · protections · deletions · page moves · rights · RfA), Bakasuprman (talk · contribs), Dangerous-Boy (talk · contribs) and Sbhushan (talk · contribs), Rama's Arrow alleges that the others acted as meatpuppets of banned user Hkelkar, and blocked them for six months. They deny the allegations, and allege that Rama's Arrow acted improperly in blocking them, and in posting private e-mails to the incidents noticeboard. Kirill Lokshin has proposed remedies imposing no sanctions but calling on the parties to enter into mediation, as well as a finding of fact noting the lack of reliable evidence in the case, all of which have the support of four arbitrators. However, voting on principles regarding the posting of private e-mails is split.

• TingMing: A case involving the actions of TingMing (talk · contribs). Ideogram (talk · contribs) alleges that he has engaged in "controversial edits", edit warring, incivility, and possibly sockpuppetry. TingMing denies the allegations, and alleges incivility on the part of Ideogram. Kirill Lokshin has proposed a remedy banning TingMing for one year, which has the support of three arbitrators, but is opposed by Blnguyen.

• E104421-Tajik: A case involving the actions of E104421 and Tajik. The case had been suspended to allow a referral to Community enforceable mediation, but the mediation broke down after Tajik was alleged to have edited through sockpuppets while claiming to be away and unavailable for the mediation. Remedies have been proposed banning Tajik either indefinitely or for one year (which have the support of four arbitrators), and placing E104221 on revert parole (with the support of one arbitrator).

• Transnistria: A case involving the actions of MariusM (talk · contribs) and William Mauco (talk · contribs) on Transnistria-related articles. MariusM alleges that Mauco (who has not made a statement because he is blocked) has engaged in sockpuppetry, edit warring and other misconduct. Fred Bauder has proposed remedies, with the support of four arbitrators, banning MarkStreet (talk · contribs), William Mauco (talk · contribs), MariusM (talk · contribs) and EvilAlex (talk · contribs) indefinitely from any editing related to Transnistria. Alternative proposals indefinitely banning them from the project have the support of two arbitrators, plus one "second choice".

• Zeq-Zero0000: A case involving the actions of Zeq (talk · contribs) and Zero0000 (talk · contribs). Zero alleges that Zeq has engaged in POV-pushing, while Zeq alleges that Zero has misused administrative tools in blocking him, the case in particular involving the question of whether probations, article bans, etc. can be enforced by involved admins. The arbitrators have considered several different versions of a principle covering to what degree involved administrators may enforce probation; none yet has majority support. A majority (between nine and eleven) of the arbitrators have voted to advise Zero0000 not to take further administrative actions against Zeq, including enforcement of probation, and to admonish Zero0000 that editors who are not restricted in their editing of a page or area are entitled to be accorded good faith and be treated with respect and courtesy. Arbitrator Fred Bauder proposed banning Zeq from editing articles related to the Israel-Palestine conflict, but no other arbitrator has voted in support, and four have opposed.
