The finalized build is in progress and will be distributed to signers as soon as it completes. When this occurs, the build will be published to our normal release channel (for automation, but you can watch for the change at https://releases.quilibrium.com/release), and the develop and main branches will have the finalized 2.1 update merged into both. Following the unpause of mainnet, the network will enter an extended 24 hour enrollment period for nodes so that node operators have time to manage the update. Upgrading from 2.0 to 2.1 does not require a store backup, however after upgrading, node operators should maintain regular backups of their store. As with any version, please make sure all configuration files neighboring the store folders in .config are appropriately backed up.
