The Out-Of-Sync icon displays:
In the Timeline, on each Assembly Context feature that is out-of-sync.
In the Browser, next to the external component that contains out-of-sync Assembly Context, next to the Assembly Contexts folder and next to each Assembly Context that is out-of-sync.
You can sync each Assembly Context individually, or sync all Assembly Contexts at once.
The Assembly Context updates to reflect the changes to the referenced objects.
The Assembly Contexts update to reflect the changes to the referenced objects.
