[MediaWiki-l] Semantic MediaWiki 2.4 released!

Hello everyone, We are happy to announce the immediate availability of the fifth feature release in the Semantic MediaWiki 2.x series. Semantic MediaWiki 2.4 is a feature release that adds many new features, brings numerous enhancements and fixes a good amount of bugs. It does not contain any breaking changes, so upgrading is both easy and recommended. ## Highlights ### Support for multiple languages Added support for multilingual content <https://www.semantic-mediawiki.org/wiki/Localization_and_multilingual_content>. This includes the introduction of the monolongual text datatype <https://www.semantic-mediawiki.org/wiki/Help:Type_Monolingual_text>, a new special property to describe properties <https://www.semantic-mediawiki.org/wiki/Help:Special_property_Has_property_description> and the new Semantic Interlanguage Links extension <https://www.semantic-mediawiki.org/wiki/Extension:Semantic_Interlanguage_Links> . ### Pattern based constraints Added support for constraint specification using regular expressions (#1417). The use of regular expressions and thus the Allows pattern property to express a constraint assignment is restricted to users with the smw-patternedit <https://www.semantic-mediawiki.org/wiki/Help:Permissions_and_user_rights> right. ### Positional units It is now possible to specify which position a custom unit <https://www.semantic-mediawiki.org/wiki/Help:Custom_units> should have in Corresponds to <https://www.semantic-mediawiki.org/wiki/Help:Special_property_Corresponds_to> annotations. This means you can specify [[Corresponds to::€ 1]] instead of [[Corresponds to::1 €]]. You can find a small example <http://sandbox.semantic-mediawiki.org/wiki/Issue/1329_%28Positional_unit_preference%29> on the Sandbox. ### Display precision You can now specify the precision used for display of numeric properties (i.e. those of type Number, Quantity, Temperature). This is done using the Display precision of <https://www.semantic-mediawiki.org/wiki/Help:Special_property_Display_precision_of> property. You can override this display precision per #ask query, by using -p<digit>. You can view the examples <https://github.com/SemanticMediaWiki/SemanticMediaWiki/pull/1335>. ### Enhanced date and time formatting Extended date and time formatting <https://www.semantic-mediawiki.org/wiki/Help:Type_Date> by supporting PHP's DateTime format rules. ### Display Title storage MediaWiki's {{DISPLAYTITLE:...}} can now be stored as the Display title of <https://www.semantic-mediawiki.org/wiki/Help:Special_property_Display_title_of> special property, so it can be used in queries. ## Compatibility changes Support was added for MediaWiki 1.26 and MediaWiki 1.27. SMW 2.3 has know issues with these versions of MediaWiki, so you are highly encouraged to upgrade SMW if you plan to use one of them. While SMW 2.3 already had beta support for PHP 7, this release fully supports it. This release does not drop support for anything. It is however the last release to support PHP older than 5.5 and MediaWiki older than 1.25.

The installation procedure [1] has not changed since 1.9.0. To upgrade, you will need to get the new version of SMW, follow the usual upgrading procedure of running MediaWikis update.php, and running SMWs refresh data script [2]. There is a short video showing an upgrade from SMW 2.1.3 to 2.2 at [3].
