First minor update for the latest GD bbPress Toolbox Pro, version 5.5.1 brings various updates and fixes to notifications override system and thumbnail display of attachments.
When attachments are displayed as thumbnails, and if you need to use Lightbox, the problem is how to handle PDF files: they can have a thumbnail, but Lightbox can’t load them. So, now, the plugin adds an extension CSS class to each thumbnail, and filter for the REL attribute. This can be used to avoid having PDF thumbnail used by the Lightbox. Standalone companion Lightbox plugin is also updated to work with this version of the plugin.
As for notifications, various changes are added to the system, including a bunch of new filters to allow you control over the elements used for the email message content. The function that is used to clean up the mail content and title can be overridden by the theme if you want to change how it works.
Let me know what you think about the new update, and please, report any issues if you find them.
