What do I support with Bitcoin Core Version 0.14.2 At the moment I'm following the discussion about BIP-141, BIP-148, SegWit and SegWit2x (NYA). But I'm confused.

I'm running Bitcoin Core Version v0.14.2 as a full-node. It's currently downloading the blockchain (should finish in 40 hours). So I count as a user (in regard to the term user activated soft fork) what means that I have a vote.

Now I'm wondering what I'm supporting by using version 0.14.2?
You can look at the version field of blocks generated by that software, there are websites that show both the client and version.
To my knowledge, core supports bip141, which is SegWit (bit 1 of version)
Core does not support bip91, nor bip148, nor Segwit2x (2mb hardfork)
