A new version of Bitcoin Core, 0.16.1, has been officially released by a group of 19 Bitcoin Core developers on 15 June 2018. This is the first update to Bitcoin Core since 0.16.0 in February 2018 which implemented full support for Segregated Witness (SegWit) to fit more transactions into blocks and reduce transaction fees.
In this update, the “blockmaxsize” option has been removed, and now miners should use “blockmaxweight” if they want to limit block size. Several other bugs are fixed in addition to some policy and documentation changes which can be found in the PGP signed 0.16.1 release notes. Basically, there aren’t any major changes to Bitcoin Core with this release, but it is important to be running the latest software, so Bitcoin Core users should update to 0.16.1.
