The same summary of updateable addons that shows on the ACP index (if enabled) also shows on top of the add-ons page (by default on, can be disabled in options)
When clicking the "Get your API key here"-link in the addon options, it passes along your forum's boardUrl so you don't have to worry about getting the value right
- addon.json metadata now has some useful links, thanks @otto
- possibility to ignore the current newest version
- When a newer version is released it will still notify you about the newer version
- Less clutter in admin/addon if you don't e.g. want to update to a specific version
