v26.2.1

Notes

The Nimbus consensus client v26.2.1 is a low-urgency, packaging-fix-only release for ARM and multiarch Docker images for anyone running v26.2.0 and otherwise medium-urgency due to addressing the cause of the Nimbus outage on mainnet present in v26.1.0 and earlier. Those still running v26.1.0 or previous versions on mainnet should verify they're still on the canonical chain, restart Nimbus otherwise, and regardless update. There is no change to either the beacon node or validator client between v26.2.0 and v26.2.1.

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

v26.2.0

Notes

The Nimbus consensus client v26.2.0 is a medium-urgency release with improved network stability. In particular, it addresses a scenario during which Nimbus clients falsely rejected as invalid a mainnet block and forked off. Cache corruption in Nimbus's implementation Merkle tree hashing causing this arose from certain size changes of SSZ List objects which appeared on mainnet which bypassed correct cache invalidation; status-im/nim-ssz-serialization#150 (comment) provides additional detail. Because descendants of block inaccurately determined to be invalid could not be processed without violating protocol, Nimbus could not continue to follow mainnet's canonical chain until the node was restarted. This release fills in the previously missing cases of Merkle tree root cache invalidation to prevent recurrence of such an event.

Improvements

• Simplify era file-based node startup:
  #7888

Fixes

• Fix hash_tree_root cache invalidation for SSZ Lists:
  #7951
  #7967

• Fix a validator client crash on startup with offline or unavailable beacon nodes:
  #7962

• Fix handling of validator custody changes in requesting missing columns:
  #7927

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

v25.11.1

Notes

The Nimbus consensus client v25.11.1 is a high-urgency release for mainnet due to the impending Fusaka fork and a medium-urgency release on other networks due to stability fixes. To access blobs in Fusaka and later in this release, use the --light-supernode option. The undocumented --debug-peerdas-supernode option will be removed in a pending release.

Improvements

• Introduce light supernodes to provide blobs with less resource usage:
  #7752

• Allow the consensus light client to specify finalized block hashes to sync:
  #7735

• Allow updating column custody during any slot:
  #7724

Fixes

• Fix blob and column quarantine-related hang:
  #7743

• Fix blocking of command-line-supplied invalid blocks:
  #7714

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

v25.9.2

Notes

Nimbus v25.9.2 is a medium-urgency stability-oriented release for mainnet and high-urgency release for the Hoodi, Sepolia, and Holesky testnets, due to impending Fusaka forks on each.

Fixes

• Fix crash when block without blobs is unqueued from quarantine:
  #7543

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
