In built session updated?

Does anyone know whether the inbuilt sessions that ship with modern Proteus's are identical to the ones that shipped 10 years ago? :eusa_think:

Reason I ask is that I've just rediscovered my old Proteus in the bottom of the spare room drawer where its been forgotten about for the last decade. I think it was one of the first ones built. I'm really enjoying getting back into it and was curious if the in built sessions have ever been tweaked at all for subsequent batches over the years?

Cheers
