This week and next week we're deploying a new version of MediaWiki to your wiki, as usual. This upgrade includes one-click (AJAX) patrolling, for both new page and diff patrol (see bug 7851). Also, I thought you'd want to know about these changes:
Internationalisation/localization: * Now formatted numbers in Spanish use space as separator for thousands, as mandated by the Real Academia Española. * Kurdish formatted numbers now use period and comma as separators for thousands and decimals respectively. * Narayam: removed MyBest keyboard because of failing tests and no documented reference
Template, user script, & skin hackers: * The <data>, <time>, <meta>, and <link> elements are allowed within wikitext for use with Microdata. * The HTML5 <mark> tag has been whitelisted. * jQuery upgraded from 1.8.2 to 1.8.3. * In your wiki's MediaWiki:<skin>.css, h4, h5, or h6 headings in the sidebar have to be changed to h3 to work (more details at https://gerrit.wikimedia.org/r/#/c/30361/ and bug 457)
Wikisourcers: * ProofreadPage gets an OAI-PMH API: https://www.mediawiki.org/wiki/Extension:Proofread_Page#OAI-PMH
