Calling all Validators!

We're rolling out a new upgrade for your nodes! This release introduces:

• An important fix for nodes starting an epoch in a new shard without recent DB info. This is necessary for shuffled-out validator nodes.

This enhancement ensures smooth state synchronization, even when a setGuardian transaction occurs at the epoch change. As always, ensure you're using the right Go compiler version (v1.20.7). Happy upgrading, and don't forget to join our Discord community for discussions, support, and sharing innovative ideas.
