Hello everyone,

we are happy to announce the immediate availability of the Semantic 
MediaWiki 2.5.0 release: [0,1]. This is a big release bringing a lot of 
new features and improvements as well as bug fixes.

## Version highlights

* Full-text search in property values introduced

Support for full-text search was added using the native capabilities of 
the SQL backends "MySQL"/"MariaDB" (#1481) and "SQLite" (#1801) for the 
"Text", "URL" and "Page" datatypes.

* Provenance data recording introduced

Qualifying facts using a simple provenance model is now supported 
(#1808) using existing mechanisms in defining a property specification 
together with a new "Reference" datatype.

* Property chain and language filter support in result printouts introduced

Property chains for conditions (e.g [[Located in.Capital of::Foo]]) was 
provided for some time, and now got extended (#1824) to supporting the 
syntax on print requests to retrieve values of a chain member that 
represent a page node. Values of datatype "Monolingual Text" can now use 
a language filter (#2037) to restrict the display of a value in a print 

* Edit protection for better semantic gardening introduced

Edit protection to help avoid changes to properties or other data 
sensitive pages from alterations that may cause data invalidations (e.g. 
change of a property type, inconsistent specifications etc.) or process 
disruptions. This feature integrates with MediaWiki's page protection 

* Preferred property label support introduced

Semantic MediaWiki now supports the declaration of preferred property 
labels (#1865) with the objective to show labels in a user context on 
special pages, query results, and factboxes instead of the canonical 
property label.

* Query result cache for better performance introduced

Caching of query results (#1251) was added as experimental feature to 
minimize a possible impact of query processing during and after a page 
view. This change also includes a reevaluation (#2099, #2176) of the 
query hash (used as identifier) to ensure that cache fragmentation is 
reduced and duplicate queries can share the same cache across different 

* Links in values feature now working reliably

Support for links in values for datatype "Text" was extended by 
use-cases and improved in performance as well as avoiding the former 
error-prone "PCRE-approach".

* Fixed properties now a stable feature

Support for fixed properties was overhauled, fixed (#2135) and is no 
longer experimental.

* Special page "SemanticMediaWiki" formerly "SMWAdmin" overhauled and 

Special page "SemanticMediaWiki" formerly known as special page 
"SMWAdmin" was modernized and extended (#2044, etc.) including a new 
configuration setting allowing for a more fine-granded control over 
feature accessibilty (#2142).

See the release notes [0] for these highlights and for much more 
information on the features, enhancements, changes as well as fixes this 
release additionally brings to you.
