• Fix threadmark search options on the advanced search page would cause unexpected page reflows
• Fix "json_decode(): Passing null to parameter #1 ($json) of type string is deprecated"

• Fix \XF\Finder\Thread::pluckFrom would not function as expected
• Fix category selection filter not working for guests
• Change when switching tabs on a threadmark index would have the threadmark category repeated
• Add per threadmark category "Updates last threadmark date" option, defaults to true
• Add "Threadmark cache size" option, to control the number of most recent threadmarks are embedded into the thread entity.

  • Supports Svg template add-on as source image
  • And XF asset upload
• Implement pagination when viewing threadmark list in overlay and on a standalone page. Still shows the "..." loader when embedded

• Fix "Add threadmark with backdate" permission not being respected when rendering the 'add threadmark' dialog. This permission was respected when actually adding the threadmark.

• Fix merging threads did not reliably update all threadmark positions as expected, and didn't correctly merge the thread's threadmark last read tracking

• Fix support for merging posts via inline moderation tools

• Fix merge/move post inline moderation action would fail to update the source thread metadata.
• Reduce redundant work done when using inline moderation tools for post copy/merge/move and thread merge.

• Fix new threadmark alerts where being triggered for edits

• When using the "Mark threadmarks read" thread action, now marks any alerts linked to those threadmarks as read as well
• Avoid showing duplicate title when viewing a threadmark list for a thread
• Add "read thread" link for non-embeded views of the threadmark index
• Add Per-category flag for whether all threadmarked posts are added to the first post info
• Fix edge case where threads without threadmarks which had a header attached would lose the threadmark header and now allow another to be added

• Fix merging threads would not merge threadmarks from source threads into the target thread in a predictable way.

• Harden threadmark index handling of threads which were unexpectedly hard-deleted

• Fix "Error rendering widget: ...setContentFromAlias(): Argument #1 must be of type string, null given"
