Release notes
This release is marked as low-urgency - please update at your convenience.
It contains improvements to attestation effectiveness and CPU usage.
It also contains improvements to the RPC APIs, as suggested by DappNode and RocketPool, and in preparation for our refactored validator client.
Old Nimbus instances
A reminder that if you're running Nimbus with a version prior to 1.0.10 (March 2021) you are exposed to a vulnerability in our core cryptography library (this library is used by all eth2 clients). See this blst security advisory for more information. If you didn't update yet, please update as soon as you can.

We've fixed:
- REST API endpoints (#2585, #2586)
/eth/v1/beacon/pool/attestations/api/eth/v1/validator/aggregate_and_proofs
- Doppelganger detection: fixed false positive on fast restart (#2656)
