Hello,

We have released Stacks version 2.1.0.0.3, available here: https://github.com/blockstack/stacks-blockchain/releases/tag/2.1.0.0.3.

This hotfix repairs a denial-of-service vulnerability where a miner may attempt to mine an invalid block.

If a miner were to encounter this bug, they would need to restart the node using this release.

Instances running in follower mode are not affected, but are encouraged to upgrade as well.

This release's chainstate directory is compatible with chainstate directories from 2.1.0.0.0.

Changelog:
## [2.1.0.0.3]

This is a high-priority hotfix release to address a bug in the
stacks-node miner logic which could impact miner availability. This
release's chainstate directory is compatible with chainstate
directories from 2.1.0.0.2.
