This version fixes an SQL error when deactivating newsletter subscribers and adds validation for the slider content element settings. In addition, the standard navigation template has been supplemented with aria-current="page". The most important improvement in this release is a change to insert tag handling, which particularly affects the {{date::Y}} (and other formats) insert tag and should significantly improve cache hits.
