Released on January 19th, 2015.

Highlights

Support for semantic queries in Special:Search

This release adds support for semantic queries run directly from MediaWiki's standard search. You can enable this feature by setting $wgSearchType to "SMWSearch". The related configuration parameter $smwgFallbackSearchType allows specifying which search engine to fall back to in case "SMWSearch" returns no results. (#450, #496, #505)

SPARQLStore improvements

The SPARQLStore now supports concept queries (#696) and regex like queries ([[Url::~http://*query=*]] OR [[Url::~*ccc*]]) for Page and URL values (#679).

Notable performance improvements and many other fixes (can be found in the bug fix list) have been made to broaden the SPARQLStore support.

Enhanced platform support

SMW has partially supported PostgreSQL for a long time. This new release brings SMW's PostgreSQL support to the same level as MySQL and SQLite, making it the third fully supported relational database.

HHVM (HipHop Virtual Machine) 3.3 or above is now supported along with all previously supported PHP versions.

Although earlier versions of SMW probably work with MediaWiki 1.24, this new release officially supports it.
