status-im/nimbus-eth2 v23.6.1

on GitHub

Notes

Nimbus v23.6.1 is a low-urgency point release significantly improving the performance of database pruning on Nimbus instances that have accumulated history prior to April 2021 (Nimbus 1.1.0). Affected users are advised to upgrade as soon as possible in order to reduce the risk of missed attestations and blocks.

Fixes

• The legacy Nimbus database is not subjected to pruning due to the high I/O cost of the operations:
  #5116

Nimbus v23.6.0 was a medium-priority upgrade, further improving the efficiency and the standards-compliance of Nimbus while laying out the foundations for the upcoming Deneb hard-fork.

Improvements

• The --history:prune option is now enabled by default.

• Nimbus can now process untimely attestations without triggering expensive state replays, resulting in increased resilience:
  #4911

• The Keymanager API can now be used to perform voluntary exits:
  #5020
  https://ethereum.github.io/keymanager-APIs/?urls.primaryName=dev#/Voluntary%20Exit

• The Nimbus validator client now leverages the more efficient support for SSZ responses of the Beacon API:
  #4999

• Full support for the upcoming Shapella hard-fork on the Gnosis chain:
  #5114

Fixes

• The support for interacting with the Beacon API from CORS-enabled clients has been restored:
  #5028

• The Nimbus beacon node will no longer inappropriately report el_offline=true when fully synced:
  #4991

• The Nimbus validator client will no longer occasionally fail to perform sync committee duties in the first slot of every epoch:
  #5083
  #5084

• Nimbus will no longer refuse to import certain valid SPDIR files (slashing protection interchange format):
  #4997

• The Nimbus behavior differed in minor ways from the Ethereum's fork-choice and honest validator specifications:
  #4992
  #5002

• The Nimbus beacon node was leaking a small amount of memory during a build-up of peer-to-peer block syncing requests:
  #4697

• The Nimbus validator client is now compatible with Lighthouse beacon nodes as it no longer exceeds the maximum allowed number of validator indices per request to the /eth/v1/beacon/states/{state_id}/validators endpoint:
  #5082

  We are deeply grateful to @jshufro for contributing important fixes in two consecutive Nimbus releases!

Removed functionality

• The implementation of the phase0-specific Beacon API endpoint /eth/v1/debug/beacon/heads has been removed:
  #5058

• The Web3Signer support for performing the phase0-specific V1 block signing requests has been removed:
  #5014

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
