Hi,

Using the current infrastructure, the best way is letting NVDA query a table of add-on identifiers and versions, which must be updated whenever new add-ons are registered and updates are released (still a manual intervention). Note that this fails for add-ons that receive updates from websites other than GitHub and ones that come with their own update mechanism. All this will change once add-ons store idea becomes reality, which will also make Add-on Updater and update mechanisms in other add-ons obsolete.

Cheers,

Joseph
