The release includes a bugfix, a cleanup made after the transition to 2.0, and support for specifying peers via DNS in the command line.
DNS peers
You can now use domain names of your trusted peers on startup. E.g. to use the Arweave peers, you may specify
peer sfo-1.na-west-1.arweave.net peer nyc-1.na-east-1.arweave.net peer tor-1.na-east-2.arweave.net peer ams-1.eu-central-1.arweave.net
A post-2.0 cleanup
There are changes to the miner's bookkeeping, which reduce the memory footprint and increase the reliability of the miner.
A bugfix
A bug was fixed which caused nodes under some very specific conditions to get stuck recovering from a fork.
