Version 1.5 is now available. I don’ have ALL the changes in, but some important ones.
= 1.5 [21-Nov-2016]=
* Enhancement: Improve the way the Digests settings are displayed in the WP user profile screen
* Added: Added default instant forum notification preference in Settings > Forums > Email Notifications.
* Fix: Show Digests settings if Overrides are on, even if no roles are selected.
You should be notified in your WP Admin just like you do for regular/free plugins. If you don’t, be sure to click ‘Check Again’ a couple of times and it should show up.
