I don't think Bitcoin 2.0 means what you think it means.
extra features and technology on the blockchain?
Yeah, that's NOT Bitcoin 2.0. That's just technology built on top of Bitcoin, but not Bitcoin itself.
Bitcoin is currently at version 0.9.3 (Bitcoin Core, the reference client).
I am pretty sure you would not like this but the crypto community consider "bitcoin 2.0" to be technology that is a descendant of bitcoin , something that will replace it or co-live with it. It does not relate literally to bitcoin blockchain it is usually in a different blockchain. And yes I am pretty aware of the current version of Bitcoin and that it has nothing to do with bitcoin 2.0 term ( it is a term not related to versioning )
