Notes
The Nimbus consensus client v26.2.1 is a low-urgency, packaging-fix-only release for ARM and multiarch Docker images for anyone running v26.2.0 and otherwise medium-urgency due to addressing the cause of the Nimbus outage on mainnet present in v26.1.0 and earlier. Those still running v26.1.0 or previous versions on mainnet should verify they're still on the canonical chain, restart Nimbus otherwise, and regardless update. There is no change to either the beacon node or validator client between v26.2.0 and v26.2.1.
Urgency guidelines
low-urgency: update at your own convenience, sometime within our normal update cycle of two weeks
medium-urgency: may contain an important stability fix, it is better to update sooner rather than later
high-urgency: update as soon as you can, this is a critical update required for Nimbus to function correctly
