Semantic MediaWiki 2.4 released! - MediaWiki-l

12 Jul 2016


      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.
For more information, see the compatibility overview
https://github.com/SemanticMediaWiki/SemanticMediaWiki/blob/master/docs/COMPATIBILITY.md

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]. We already started
work on SMW 2.5 and welcome your contributions [4].
