I downloaded Add-on Update Notifier 1.1.8 yesterday for my XF 2.2 forum. I plan to move to XF 2.3 soon and was looking for a simple method to determine which of my 10 installed XF 2.2 add-ons have updates available for XF 2.3.
This add-on largely does the job. After installation, it displayed a message on the ACP home page that four updates were available. I went to the ACP>>Add-ons, and a link was provided for each of the four ads-ons where an updated version of each can be download.
Two of the four available add-on updates were not identified by their developer as being compatible with XF 2.3...which is no fault of this add-on. For the other two updates, the developer specifically stated that the available update was compatible with both XF 2.2 and 2.3.
I still anticipate some add-on problems when I move to XF 2.3. However, Add-on Update Notifier helps to identify which add-ons might cause problems.
For the cost (free) this is a very useful add-on gem whether you plan to move to XF 2.3 or not.
