Summary
This release fixes a bug in Lighthouse v2.2.0 that prevented some nodes from completing sync.
The majority of nodes running v2.2.0 will not have been affected by the bug, but nodes attempting to sync from genesis would get stuck at slot 0 forever, and nodes performing checkpoint sync would fail to download blocks from before the Altair hard fork (Oct 2021). The bug occurred as a result of changes made to RPC limits in preparation for the Merge, and has been fixed in PR #3146. Please see that pull request for more detail.
Users upgrading from v2.1 should also read the release notes for v2.2.0 to understand a new protocol feature called proposer boost which has been enabled in v2.2: https://github.com/sigp/lighthouse/releases/tag/v2.2.0
Backwards Compatibility
This release is fully backwards-compatible with the previous releases v2.2.0 and v2.1.x.
Downgrading from v2.2.1 to v2.1.x is also supported without any manual intervention.
