  • Requires Thread starter alerts v2.5.0+ add-on to actually use

  Supports [searchcontent] bb-code from Advanced BbCodes pack, and autocomplete from ElasticSearch Essentials.

• Update to better support new "INP" or "Interaction to Next Paint" by avoiding triggering repaint/reflow of content on threadview due to attempting to fit too many categories inline with the top page nav controls

• Add sort-threadmark link per recent threadmark list if the user can sort threadmarks

• Fix "SV\Threadmarks\Job\Cache::getNextIds(): Return value must be of type array, null returned" error generated when installing add-on.

• Require Standard Library by Xon v1.18.0+
• Implement XF2.2 LinkableInterface interface for various entities where it makes sense
• Change 'threadmark-index-icon' to silently return an empty string is passed null for the threadmark index, and allow the href parameter to work without being in update mode

• Fix unknown template macro error on creating a new thread when a threadmark index is required but a user isn't permitted to create one
• Add 'backdate' option when adding a threadmark
  • Sets the threadmark create date to the content's, and sets the threadmark creator to the thread/conversation starter
