Announced masternode blinding - not delivered.
Announced on chain anon (ring sigs) - not delivered.

Those are two off the top of my head, but I'm sure there are others.

I don't even necessarily consider these a bad thing, as changing priorities and direction during development is fine.

But I say let's wait and see until we can fully evaluate Evolution in terms of not only its claimed (and then delivered) benefits but also costs, compromises, and drawbacks.
