= MediaWiki release notes = Security reminder: MediaWiki does not require PHP's register_globals setting since version 1.2.0. If you have it on, turn it '''off''' if you can. == MediaWiki 1.19 == THIS IS NOT A RELEASE YET MediaWiki 1.19 is an alpha-quality branch and is not recommended for use in production. === Configuration changes in 1.19 === * Removed SkinTemplateSetupPageCss hook; use BeforePageDisplay instead. * (bug 27132) movefile right granted by default to registered users. * Default cookie lifetime ($wgCookieExpiration) is increased to 180 days. * (bug 31204) Removed old user.user_options * $wgMaxImageArea now applies to jpeg files if they are not scaled with ImageMagick. * Introduced $wgQueryPageDefaultLimit (defaults to 50) for the number of items to show by default on query pages (special pages such as Whatlinkshere). === New features in 1.19 === * (bug 19838) Possibility to get all interwiki prefixes if the interwiki cache is used. * $wgDnsBlacklistUrls now accepts an array with url and key as the elements to work with DNSBLs that require keys, such as Project Honeypot. * (bug 30022) Add support for custom loadScript sources to ResourceLoader. * (bug 19052) Unicode space separator characters (Zs) now terminates external links and images links. * (bug 30160) Add public method to mw.loader to get module names from registry. * (bug 15558) Parameters to special pages included in wikitext can now be passed as with templates. * Installer now issues a warning if mod_security is present. * (bug 29455) Add support for a filter callback function in jQuery byteLimit plugin. * Extensions can now participate in the extraction of titles from url paths * Added two new GetLocalURL hooks to better serve extensions working on a limited type of titles. * Added a --no-updates flag to importDump.php that skips updating the links tables. * Most presentational html attributes like valign are now converted to inline css style rules.

This can be disabled using $wgCleanupPresentationalAttributes. * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not NAMESPACE) now depend on the page content language instead of the site language.

PHP 4 is no longer supported. MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but support for them is somewhat less mature. There is experimental support for IBM DB2 and Microsoft SQL Server. The supported versions are: * MySQL 4.0 or later * PostgreSQL 8.3 or later * SQLite 3 * Oracle 9.0.1 or later == Upgrading == 1.19 has several database changes since 1.18, and will not work without schema updates. If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes. If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data. If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed upgrade instructions. For notes on 1.17.x and older releases, see HISTORY. == Online documentation == Documentation for both end-users and site administrators is available on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain): http://www.mediawiki.org/wiki/Documentation == Mailing list == A mailing list is available for MediaWiki user support and discussion: http://lists.wikimedia.org/mailman/listinfo/mediawiki-l A low-traffic announcements-only list is also available: http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes. == IRC help == There's usually someone online in #mediawiki on irc.freenode.net.
