I am happy to announce the 1.0 release of the Semantic Extra Special Properties extension!
This release fixes various issues and makes the extension compatible with the latest MediaWiki, Semantic MediaWiki and PHP versions. It adds several new special properties such as PAGEID and EXIFDATA, as well as providing performance improvements. A more verbose, though also more technical, overview of the changes can be found here.
For upgrading you will need to run update.php and it is recommended you also run SMW_refreshData.php. Documentation on how to configure the extension can now be found here.
As of this release is is also possible to install the extension via Composer. (Manual installation is still supported.) The package name is “mediawiki/semantic-extra-
Many kudos go to MWJames for doing essentially all of the development work in this new version. I’d also like to thank Karsten for helping with the documentation and testing.
