CLTV is over a year old at this point. Segwit doesn't look like it's going to reach consensus anytime soon which means lightning implementations are doa.
Compact blocks are definitely an improvement for the network though.
2 years of community infighting. I don't see any better tech that is relevant to most users just edge cases. I don't actually see fewer scams at all. The whole ICO market is basically a giant set of scams for one example and they are exploding. We've had multiple large exchange thefts this year as well.
