Skosmos 2.18

This is a minor version release (2.18) of Skosmos which contains several bug fixes as well as improvements to search engine and social media sharing metadata. There are also updated to the UI translations in Latvian, Norwegian Bokmål and Norwegian Nynorsk.

Due to the EasyRdf upgrade, we had to drop support for PHP 7. From now on, Skosmos 2 only works on PHP 8.0 and 8.1. Skosmos 3 will support more modern PHP versions.

We already said this for 2.17, but this will most likely be the final release in the Skosmos 2 series, unless serious bugs are discovered. Current Skosmos development is focused on Skosmos 3.
