As @eko said the updates are daily, for real. Just for Nov & Dec there are 96 revisions.
So an update alert would be nice, only if major changes or new features are introduced. This is up for the developers to decide.
So the answer is Manager is updated daily, you can update every day, but would you do it? Also considering that the updates may break some things like HERE then you can book mark the releases page and see what you’ve missed.
But again, for major changes or must-have features there should be an alert mechanism.
