For those who didn't notice, finally Bech32 address format (the native format for SegWit addresses) has been merged into bitcoin core.

What this means is that from now on it is possible to generate and use native segwit addresses from within core. Using these addresses have a number of advantages.  To number some, they have error correction and hinting built-in, are optimized to be human readable, and using them takes less bytes on the blockchain  (thus lowering fees even more) when compared with segwit P2SH wrapped addresses (those starting with 3...).

Wallet support for Bech32 is non-existent right now. But this is a step further in the right direction.
