v25.9.0

Notes

Nimbus v25.9.0 is a low-urgency release which increases the resiliency and efficiency of block production. Furthermore, macOS amd64 releases have been deprecated and will be discontinued by October 2025.

Improvements

• Allow fallback to builder API if EL provides invalid requests:
  #7396

• Propose blocks more efficiently when the builder API is enabled:
  #7353

• Log execution addresses more readably:
  #7325

Fixes

• Avoid crashing on startup when data directory can't be created:
  #7326

• Require matching Electra fork configurations between beacon node and REST clients:
  #7321
  #7322

• Fix dropped connections being interpreted as empty lists during syncing:
  #7318

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal monthly update cycle

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

v25.7.0

Notes

Nimbus v25.7.0 is a low-urgency release, except for usage of the validator client with non-Nimbus beacon nodes for which it's a medium-urgency release.

Improvements

• Increase default builder API gas limit to 45M:
  #7234

• Ensure that validator client attests in a timely way even with partially unresponsive beacon nodes:
  #7276

• Implement postStateValidatorIdentities beacon API endpoint:
  #7223

• Implement getDebugDataColumnSidecars beacon API endpoint:
  #7237

Fixes

• Fix sync-related crash regression in v25.6.0:
  #7275

• Restore validator client compatibility with beacon nodes providing BPO schedules:
  #7219

• Add missing finalized field to getStateV2 beacon API endpoint:
  #7248

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

v25.6.0

Notes

Nimbus v25.6.0 is a low-urgency release.

Improvements

  #7198

• Remove deprecated Eth1Data polling for deposits in favor of EIP6110:
  #7114

Fixes

• Implement getPendingConsolidations and add version field to getPendingDeposits and getPendingPartialWithdrawals beacon API endpoints:
  #7170

• Add missing finalized field to getStateRandao beacon API endpoint:
  #7171

v25.5.0

Notes

Nimbus v25.5.0 does not alter the beacon node, is a low-urgency release for nodes which don't use the Nimbus validator client with a non-Nimbus BN, and a high-urgency release for nodes which do use the Nimbus validator client with a non-Nimbus beacon node.

Fixes

• fix missing Eth-Consensus-Version header in validator client publishBlindedBlockV2 beacon API requests:
  #7140

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal monthly update cycle

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

v25.4.1

Notes

Nimbus v25.4.1 is a high-urgency release for Ethereum and Gnosis mainnets due to their Pectra hardforks.

Fixes

• fix potential missed MEV blocks starting with Electra builder API:
  #7103

• fix single_attestation SSE beacon API stream subscription:
  #7107

Urgency guidelines

low-urgency: update at your own convenience, sometime within our normal update cycle of one month

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
