The update removes class extension hack that keeps XenForo version compatibility between 2.x versions and now the hack is in the add-on https://xnforo.ir/resources/al-compatability-layer.6101/history which is required by appropriate add-ons that need this functionality.
The issue affects our Link Checker add-on, where the posts were not indexed correctly due to incorrect order of fetching the post IDs. Please install this version to apply the fix.
The version contains minor enhancements in the admin panel for add-ons that are using the Core package for list of items. Please upgrade if any of our add-ons require the newest version of this package.
