New Version of Bitcoin Core Supports SegWit Addresses

On February 26, 2018, the new version of bitcoin core 0.16.0 was released with complete support for SegWit addresses, p2sh-SegWit, and bech32 addresses.

A new version of Bitcoin Core, version 0.16.0 is out. It supports SegWit as well as legacy,  p2sh-SegWit (default) and bech32 addresses. New functionality will dictate which type of address to generate and use. It is also possible to downgrade after creating a SegWit address if the wallet file is up to date. It is also possible to recover an old backup of SegWit keys using the new software.

With the new functionality, users can generate and send funds to BIP173 addresses including the non-v0 ones. However, wallets created with the latest software update will not work with older software versions of Bitcoin Core.
