            Hey <@&1122981184255840306>! A new version of the ZetaChain software has been released.

            Major Version Upgrade (e.g. v5.x.x to V6.x.x) must be completed through a governance proposal.
            We will submit a governance proposal in the next few days.
            More specific information including block height will be shared as part of the governance proposal.

            See the release notes for more details. https://github.com/zeta-chain/node/releases/tag/${{ env.BINARY_VERSION }}
