Summary

This release mainly brings support for recent versions of MediaWiki. A small number of fixes and enhancements where also made. Anyone using MediaWiki 1.35 is recommended to upgrade. Using versions of SMW older than 4.0 on MediaWiki 1.36 or above is not supported.

Compatibility

  • Added support for MediaWiki 1.36 and MediaWiki 1.37
  • Improved compatibility with MediaWiki 1.38, though this version still has many issues
  • Improved support for MediaWiki 1.35
  • Dropped support for MediaWiki older than 1.35
  • Dropped support for PHP older than 7.3

For more detailed information, see the compatibility matrix.

Upgrading

Calling wfLoadExtension is now required in the "LocalSettings.php" file. Example:

wfLoadExtension( 'SemanticMediaWiki' ); enableSemantics( 'example.org' );

There is no need to run the "update.php" maintenance script or any of the rebuild data scripts.

When a triplestore is used with the SPARQL feature SMW_SPARQL_QF_COLLATION, the "updateEntityCollation.php" maintenance script must be run (the collation sort key algorithm was changed).
