IMPORTANT UPDATE

On block #262,080, the network successfully upgraded to version 2.0.0. Please upgrade your node to Grin v2.0.0 and wallet to Grin-Wallet 2.0.0.

Grin v2.0.0 and Grin-wallet v2.0.0, which include support for the upcoming hard fork, have been released. Changes in these releases have been almost entirely focused on hard fork support and ensuring the entire ecosystem will be running the same version of the transaction-exchange format (the Slate) post-upgrade.

These are required updates for all users, and we recommend everyone take the opportunity to update as soon as possible.
