v2.1.4

As we prepare our v3 mainnet release for The Merge, v2.1.4 marks the end of the v2 era. Node operators and validators are highly encouraged to upgrade to release v2.1.4 - many bug fixes and improvements have been included in preparation for The Merge. v3 will contain breaking changes, and will be released within the next few weeks. Using v2.1.4 in the meantime will give you access to a more streamlined user experience. See our v2.1.4 doc to learn how to use v2.1.4 to run a Merge-ready configuration on the Goerli-Prater network pair.
