# Semantic MediaWiki 2.1
|
|
|
|
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 `$wgSearchType` to ["SMWSearch"](https://semantic-mediawiki.org/wiki/Help:SMWSearch).
|
|
The related configuration parameter [``$smwgFallbackSearchType``](https://semantic-mediawiki.org/wiki/Help:$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.
|
|
