We have changed how you can configure notification channels for your Rosters. Going forward, you need to add the @RosterBird bot to any channels you want to configure for your rosters.
This is to simplify your Roster setups and bring more transparency. Also this will allow us to build more integrations with the channels beyond notifications. We recently rolled out Channel topics and we have similar features in the works.
Your existing rosters / channel integrations will continue as it is, you do not have to change anything.
Please write to us if you have any questions or issues!
