v23.2.0

Notes

Nimbus v23.2.0 is a low-urgency upgrade providing full support for the upcoming
Capella hard-fork on the Sepolia testnet. Keep an eye out for future mainnet releases!

Improvements

• Status now provides an APT repository that will host the latest version of the
  Nimbus beacon node and validator client software:
  https://apt.status.im/

• The deposits import command now provides the option --method=single-salt which
  will significantly improve the keystore loading speed on start-up on beacon nodes
  and validator clients running with a very large number of validators. Please see
  the documentation provided in the Nimbus guide in order to understand the security
  implications of using the option:
  https://nimbus.guide/keys.html#optimised-import-for-a-large-number-of-validators
  #4372

• More efficient sync committee caching strategies bring 20-30% of syncing
  speed improvement post Altair:
  #4592

• Nimbus performs fewer interactions with the EL node during optimistic syncing
  which further improves the syncing speed:
  #4591

• The Keymanager API now supports all gas_limit end-points:
  https://ethereum.github.io/keymanager-APIs/#/Gas%20Limit
  #4612

• Nimbus serves light client updates up to the retention period mandated by
  the spec even when pruning is enabled:
  #4499

• The Linux packages of Nimbus no longer depend on lsb-release:
  #4597

• The list of bootstrap nodes for the Gnosis network has been expanded:
  #4603

• Nimbus now performs fewer forkchoiceUpdated Engine API calls with lower risk
  of reporting conflicting data to the EL node:
  #4609
  #4614
  #4623

Fixes

• Nimbus will no longer suffer from performance issues when a large number of
  non-active validators are imported in the beacon node or the validator client:
  #4590

• Nimbus will no longer crash when it fails to resolve the hostname of a remote
  validator imported through the Keymanager API:
  #4590

• The Nimbus validator client won't attempt to perform sync committee duties when
  the attached beacon node is only optimistically synced:
  #4622

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
