With this version's release, the add-on has temporarily been made compatible with the XenForo 2.0.X line. This is the final major update for the 2.0.X line.
Changes in 1.0.6:
Added feedback widget for listing view
Added feedback tab to user profile
Added the ability to link multiple categories to a single node.
Added alert when a user marks you as the buyer of their item.
Added an option for replacing "post new thread" with "post new listing" on a forum's thread list. This will now show an overlay similar to yoursite.com/classifieds/new but only with applicable categories.
Added the ability to edit user feedback via ACP.
Added feedback score as a user criteria
Added feedback to quick stat pairs
Added missing search form for listings
Changes for 2.1.X users:
Removed bookmarks, push notifications, and reaction support.
This had to be done so that I could make both versions compatible, sorry. These features will return once the add-on is 2.1.X only again.
