Bitcoin Core 0.16.1 Released

Bitcoin Core 0.16.1 Released

Bitcoin Core version 0.16.1 is now available for download. All users are encouraged to upgrade to this maintenance
release
that fixes several bugs and provides backports of new minor
features, such as:

  • Mitigating a vector for denial-of-service attacks. This attack required
    compromising particular services and would’ve probably been most
    effective against nodes that were started for the first time (rather
    than nodes that had already been connected to the network for more
    than a few hours).

  • Fixing a bug that could’ve potentially caused miners to lose revenue if
    they produced two blocks in very rapid succession.

  • Ceasing relay of transactions using the rarely-seen OP_CODESEPARATOR opcode for legacy
    (non-segwit) signature scripts. The presence of this opcode makes it
    difficult for nodes to estimate how much computational work will be
    required to validate a legacy signature script. Because of that, it
    blocks the deployment of solutions to prevent attackers from creating
    blocks that require a long time to validate. By itself, this change
    to relay policy doesn’t fix the problem itself, but it does make it
    easier and safer to deploy proposed solutions in the future should
    users consent to adopt them.

For a complete list of changes, please see the release notes. If
have any questions, please stop by our IRC chatroom and we’ll do
our best to help you.
