on GitHub

Notes

Nimbus v22.10.0 is a medium-urgency release, continuing our accelerated release schedule and bringing further stability and performance improvements after the merge.

Improvements

• Faster block production, bringing practical benefits on low-powered devices such as the Raspberry Pi:
  #4184
  #4196

• The Nimbus validator client can now work with multiple beacon nodes with configurable responsibilities:
  #4113
  #4140

• The /eth/v2/validator/blocks/{slot} API now features an optional randao_reveal parameter in accordance to the latest Beacon API spec:
  ethereum/beacon-APIs#222
  #3837

• The /eth/v1/beacon/blocks API now supports SSZ-encoded payloads:
  #4154

• The new metrics beacon_block_builder_proposed, beacon_block_builder_missed_with_fallback and beacon_block_builder_missed_without_fallback can help you track the successful and failed attempts to use the configured external block builder:
  #4158

Fixes

• Rare, but critical conditions manifesting primarily in the Goerli network were leading to an unrecoverable database corruption:
  #4174
  #4192

• If the chain was re-orged while Nimbus is shut down, this created a low risk that the client may become stuck on a non-canonical block:
  #4161

• Nimbus was not serving the best possible light client updates when back-filling after a trusted node sync:
  #4195

Upcoming breaking changes

• The pre-altair REST API paths /eth2/beacon_chain/req/beacon_blocks_by_{range,root}/1/ are now deprecated and will be removed in the next Nimbus version. Since these APIs support only phase0 responses, it is unlikely that there are any remaining clients using them.

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
