Upgrade to this release is required

Network Upgrade at Block 1,800,000

The v0.18.0 release of the core TurtleCoin suite activates a network upgrade at block 1,800,000 that implements block major version 6. Block major version 6 changes the Proof-of-Work (PoW) algorithm to Chukwa. Please be sure to update your miners before the network upgrades to continue mining. We're working on the final steps to make sure the algorithm is supported in the most common mining packages and will post news in the official TurtleCoin blog as we are made aware of additional miners supporting the algorithm. In addition to the blog, we urge users to join the TurtleCoin Discord and type *news to be added to the announcements list to be notififed of the latest TurtleCoin updates.
