Updates will now be checked automatically at the frequency chosen in the addon preferences.
If an update is available, a prompt will show up and suggest to update.
That prompt contains a button to display the Release Notes, and a button to open the QuickSnap preferences if the user wants to disable the auto update check.
A link to the release notes has also been added in the addon preferences.
The automatic update check is now enabled by default for users installing hte addon for the first time.
