The release fixes a bug that would cause deleting all attachments in a post when one of them gets deleted. This was related to a conflict with XenForo core JavaScript, that would consider the checkbox meant for the thumbnail selection as a checkbox for deletion of attachments. We have updated the UI to use Radio buttons, and clicking a radio button one more time will unselect it, just in case you need to disable manual selection of any thread thumbnail.

From now on, the options "Enable/Disable Product" and "Enable/Disable Automatic Thumbnail" will not require listing all forums by hand in the option "Enable only in the following forums" or "Disable only in the following forums" - the children of the listed forums will be automatically considered enabled.

This is a breaking change so please verify your configuration after the upgrade.

The release also applies a minor change to the "Rebuild thread thumbnails" Admin panel tool and will now include all threads that already have an automatically detected thumbnail, to allow re-detection of thumbnails, in case there has been a change in the order of attached images or third-party products have modified the way automatic thumbnail detection works.

In this release, we have created a new option called "Hide thumbnail in attachments".

With the option enabled the attachment which is used as a thumbnail will not be shown in the Attachments block under its post.

This release fixes a bug with the image in thread metadata being the thumbnail instead of the full version, which would cause lower quality preview image when the thread is shared on social media.

This release fixes a compatibility issue on XenForo 2.2.x where it wasn't possible to change the thread thumbnail manually.

It also includes a fix for a bug causing users without "Change Own Thread's Thumbnail" permission to see the Set Thumbnail checkbox while editing the first post. This fix applies to all XenForo versions.
