v5.2.0

Important

This release is mandatory for all validator clients using mev-boost with a gas limit increase. Without upgrading to this release, validator clients will default to using local execution blocks when the gas limit starts to increase.

Updating to this release is highly recommended, especially for users running v5.1.1 or v5.1.2.

This release has several fixes and new features. In this release, we have enabled QUIC protocol by default, which uses port 13000 for --p2p-quic-port. This may be a breaking change if you're using port 13000 already. This release has some improvements for raising the gas limit, but there are known issues with the proposer settings file provided gas limit not being respected for mev-boost outsourced blocks. Signalling an increase for the gas limit works perfectly for local block production as of this release. See pumpthegas.org for more info on raising the gas limit on L1.

Notable features:

  • Prysm can reuse blobs from the EL via engine_getBlobsV1, potentially saving bandwidth.
  • QUIC is enabled by default. This is a UDP based networking protocol with default port 13000.

Added

  • Electra EIP6110: Queue deposit pr.
  • Add Bellatrix tests for light client functions.
  • Add Discovery Rebooter Feature.
  • Added GetBlockAttestationsV2 endpoint.

  • Added SubmitPoolAttesterSlashingV2 endpoint.
  • Added SubmitAggregateAndProofsRequestV2 endpoint.
  • Updated the beacon-chain/monitor package to Electra. PR
  • Added ListAttestationsV2 endpoint.
  • Add ability to rollback node's internal state during processing.
  • Change how unsafe protobuf state is created to prevent unnecessary copies.
  • Added benchmarks for process slots for Capella, Deneb, Electra.
  • Add helper to cast bytes to string without allocating memory.
  • Added GetAggregatedAttestationV2 endpoint.
  • Added SubmitAttestationsV2 endpoint.
  • Validator REST mode Electra block support.
  • Added validator index label to validator_statuses metric.
  • Added Validator REST mode use of Attestation V2 endpoints and Electra attestations.
  • PeerDAS: Added proto for DataColumnIdentifier, DataColumnSidecar, DataColumnSidecarsByRangeRequest and MetadataV2.
  • Better attestation packing for Electra. PR
  • P2P: Add logs when a peer is (dis)connected. Add the reason of the disconnection when we initiate it.
  • Added a Prometheus error counter metric for HTTP requests to track beacon node requests.
  • Added a Prometheus error counter metric for SSE requests.
  • Save light client updates and bootstraps in DB.
  • Added more comprehensive tests for BlockToLightClientHeader. PR

Changed

  • Electra EIP6110: Queue deposit requests changes from consensus spec pr #3818
  • reversed the boolean return on BatchVerifyDepositsSignatures, from need verification, to all keys successfully verified
  • Fix engine_exchangeCapabilities implementation.
  • Updated the default scrape-interval in Client-stats to 2 minutes to accommodate Beaconcha.in API rate limits.
  • Switch to compounding when consolidating with source==target.
  • Revert block db save when saving state fails.
  • Return false from HasBlock if the block is being synced.
  • Cleanup forkchoice on failed insertions.
  • Use read only validator for core processing to avoid unnecessary copying.
  • Use ROBlock across block processing pipeline.
  • Added missing Eth-Consensus-Version headers to GetBlockAttestationsV2 and GetAttesterSlashingsV2 endpoints.
  • When instantiating new validators, explicit set Slashed to false and move EffectiveBalance to match struct definition.
  • Updated pgo profile for beacon chain with holesky data. This improves the profile guided
    optimizations in the go compiler.
  • Use read only state when computing the active validator list.
  • Simplified ExitedValidatorIndices.
  • Simplified EjectedValidatorIndices.
  • engine_newPayloadV4,engine_getPayloadV4 are changes due to new execution request serialization decisions, PR
  • Fixed various small things in state-native code.
  • Use ROBlock earlier in block syncing pipeline.
  • Changed the signature of ProcessPayload.
  • Only Build the Protobuf state once during serialization.
  • Capella blocks are execution.
  • Fixed panic when http request to subscribe to event stream fails.
  • Return early for blob reconstructor during capella fork.
  • Updated block endpoint from V1 to V2.
  • Rename instances of "deposit receipts" to "deposit requests".
  • Non-blocking payload attribute event handling in beacon api pr.
  • Updated light client protobufs. PR
  • Added Eth-Consensus-Version header to ListAttestationsV2 and GetAggregateAttestationV2 endpoints.
  • Updated light client consensus types. PR
  • Update earliest exit epoch for upgrade to electra
  • Add missed exit checks to consolidation processing
  • Fixed pending deposits processing on Electra.
  • Modified ListAttestationsV2, GetAttesterSlashingsV2 and GetAggregateAttestationV2 endpoints to use slot to determine fork version.
  • Improvements to HTTP response handling. pr
  • Updated Blobs endpoint to return additional metadata fields.
  • Made QUIC the default method to connect with peers.
  • Check kzg commitments align with blobs and proofs for beacon api end point.
  • Revert "Proposer checks gas limit before accepting builder's bid".
  • Updated quic-go to v0.48.2 .

Deprecated

  • /eth/v1alpha1/validator/activation/stream grpc wait for activation stream is deprecated. pr
  • --interop-genesis-time and --interop-num-validators have been deprecated in the beacon node as the functionality has been removed. These flags have no effect.

Removed

  • Removed finalized validator index cache, no longer needed.
  • Removed validator queue position log on key reload and wait for activation.
  • Removed outdated spectest exclusions for EIP-6110.
  • Removed support for starting a beacon node with a deterministic interop genesis state via interop flags. Alteratively, create a genesis state with prysmctl and use --g enesis-state. This removes about 9Mb (~11%) of unnecessary code and dependencies from the final production binary.
  • Removed kzg proof check from blob reconstructor.

Fixed

  • Fixed mesh size by appending gParams.Dhi = gossipSubDhi
  • Fix skipping partial withdrawals count.
  • wait for the async StreamEvent writer to exit before leaving the http handler, avoiding race condition panics pr
  • Certain deb files were returning a 404 which made building new docker images without an existing
    cache impossible. This has been fixed with updates to rules_oci and bazel-lib.
  • Fixed an issue where the length check between block body KZG commitments and the existing cache from the database was incompatible.
  • Fix --backfill-oldest-slot handling - this flag was totally broken, the code would always backfill to the default slot [pr](https://github.com/prysmaticlabs/prysm/pul
    l/14584)
  • Fix keymanager API should return corrected error format for malformed tokens
  • Fix keymanager API so that get keys returns an empty response instead of a 500 error when using an unsupported keystore.
  • Small log imporvement, removing some redundant or duplicate logs
  • EIP7521 - Fixes withdrawal bug by accounting for pending partial withdrawals and deducting already withdrawn amounts from the sweep balance. [PR](https://github.com/pry
    smaticlabs/prysm/pull/14578)
  • unskip electra merkle spec test
  • Fix panic in validator REST mode when checking status after removing all keys
  • Fix panic on attestation interface since we call data before validation
  • corrects nil check on some interface attestation types
  • temporary solution to handling electra attesation and attester_slashing events. pr
  • Diverse log improvements and comment additions.
  • Validate that each committee bitfield in an aggregate contains at least one non-zero bit
  • P2P: Avoid infinite loop when looking for peers in small networks.
  • Fixed another rollback bug due to a context deadline.
  • Fix checkpoint sync bug on holesky. pr
  • Fix proposer boost spec tests being flakey by adjusting start time from 3 to 2s into slot.
  • Fix segmentation fault in E2E when light-client feature flag is enabled. PR
  • Fix searchForPeers infinite loop in small networks.
  • Fix slashing pool behavior to enforce MaxAttesterSlashings limit in Electra version.
