Some course teams are actively using updates, and would like to ensure that the first update is always visible to their learners. They would prefer to use this in preference to welcome messages, which are dismissable and transient.
We need this story to be scoped small so that we can land it quickly to satisfy our partners who want this behavior.
Create a new updates fragment which shows
The most recent update, set once per session, and shown every new session.
A heading labeled "Latest Update"
Retain dismissibility for the update within that session.
Conditionally show this fragment in preference to the welcome message fragment
What mechanism should be used to determine which courses show updates
A new Waffle flag (Marco --> +1 )
Can we reuse the existing tool event? Do we need to distinguish it? (Marco: Should be the same tool in sidebar I think)
