Notes

Nimbus v22.11.0 is a low-urgency release, bringing the first
production-ready version of the Nimbus validator client.
The validator client will enable advanced users such as professional
institutional operators to take advantage of features such as support
for redundant beacon nodes, enhanced validator privacy and
distributed keystores. Meanwhile, existing users still can use
the streamlined stand-alone beacon node setup, as this mode of
operation will continue to be supported and improved.

Improvements

• The Nimbus validator client graduates from BETA to production-ready
  status after numerous improvements and fixes:

  https://nimbus.guide/validator-client.html

• The Nimbus beacon node is now compatible with validator clients
  taking advantage of the /eth/v1/beacon/blinded_blocks end-point:

  #4286

• The validator keystore loading during start-up is now 3x faster:

  #4301

• The doppelganger detection now protects validators added
  on the fly through the Keymanager API:

  #4304

• Fine-tuned internal task scheduling can provide better
  quality-of-service protections for performing all validator
  duties in the presence of syncing peers performing large
  number of concurrent block download requests:

  #4254

• The --optimistic mode of the beacon node allows you to
  stay synced with the network even without an execution layer
  node:

  https://nimbus.guide/optimistic-sync.html#optimistic-mode
  #4262

  Please note that this mode is less secure and intended only
  for non-critical information retrieval through the Beacon API.

• The Nimbus build for the Gnosis chain (available when compiling
  from source) has full support for the upcoming merge:

  #4330
  https://forum.gnosis.io/t/gip-16-gnosis-chain-xdai-gnosis-merge/1904

• The stand-alone light client (available when compiling from source)
  now preserves progress between restarts:

  #4371

Fixes

• A small risk for missing block proposals was present under heavy
  forking activity in the network due to potential inclusion of
  inappropriate attestations in the produced blocks:

  #4273

• A new batching approach for the registration of validators in the
  builder network will prevent the creation of requests of excessive
  size that might be rejected by the network. This was a problem
  affecting testnet nodes running with thousands of validators:

  #4364

Deprecated features

• The --finalized-checkpoint-block has been deprecated.
  The client will now download only the latest finalized state
  during trusted node sync:

  #4251

• The end-points /eth/v1/beacon/blocks/{block_id},
  /eth/v1/debug/beacon/states/{state_id}, and
  /eth/v1/validator/blocks/{slot} have been deprecated
  since they are no longer usable since the Altair hard-fork:

  #4279

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
