What happens to stats when a Viewlet is updated on VCL?

[Rado]

Question: What happens when someone is in the middle of a course on ViewletCentral, and the Viewlet is replaced by another version? Does the person get to finish the first course and still have the scores submitted?

Answer: When a Viewlet is updated to a newer version while someone is in the middle, they will finish the version of the course already downloaded, and their results will be recorded against this old version on ViewletCentral, since each update creates a new set of stats. Stats for older versions of a Viewlet can be accessed through "My Dashboard".
