Additions and Improvements

24.10.3

This is a recommended update with bug fixes and networking improvements.

Mekong Testnet
Note: this is the only version of Teku that supports the Mekong testnet (https://mekong.ethpandaops.io/).
Due to a bug this version does NOT support Mekong anymore, please use the mekong branch (https://github.com/Consensys/teku/tree/mekong) building it from source (more info can be found here)

Breaking Changes

N/A

Additions and Improvements

• Clean up old beacon states when switching from ARCHIVE to PRUNE or MINIMAL data storage mode
• Upgrade to jvm-libp2p 1.2.1 which brings:
  • message publishing over gossipsub improvements (addresses Failed to publish * because no peers were available on the required gossip topic)
  • IDONTWANT control message usage improvements
• Improved block production API compatibility with DVT software (i.e. SSV)

Bug Fixes

• Fixed a block production issue for Validator Client (24.10.0 to 24.10.2 Teku VC), where required headers were not provided for JSON payloads. Default SSZ block production was unaffected.
• Block production now uses json data (more like 24.8.0 did than 24.10) if the Eth-Consensus-version header is absent.

Additions and Improvements

Bug Fixes

• Fixed an issue from version 24.6.0 where Teku failed to start on machines with directly assigned public IP addresses (not running under NAT), displaying the error message: Teku failed to start: java.io.UncheckedIOException: java.net.UnknownHostException: Unable to determine local IPvx Address

Upcoming Breaking Changes

• Next release will introduce a breaking change to Teku's metrics. This is due to some metrics changing names after a library upgrade.
  We recommend all users of the Teku - Detailed dashboard to upgrade to version Revision 12
  as soon as possible. Documentation with all metrics that have been renamed will be provided.
• Next release will require Java 21. The current release is compatible, please consider upgrading before the next release.
• From the next release, you will need to explicitly set --data-storage-mode=(prune|archive) unless you're using minimal data-storage-mode (which is the default behaviour).

Breaking Changes

• Renamed --Xp2p-dumps-to-file-enabled hidden CLI option to --Xdebug-data-dumping-enabled

Additions and Improvements

• Added metadata fields to /eth/v1/beacon/blob_sidecars/{block_id} Beacon API response as per ethereum/beacon-APIs#441
• Added rest api endpoint /teku/v1/beacon/state/finalized/slot/before/{slot} to return the slot of the most recently stored state at or before the specified slot.
• The validator client will start using the v2 variant of the beacon node block publishing
  endpoints. In the cases where the block has been produced in the same beacon node, only equivocation validation will be done instead of the entire gossip validation.
• Docker images are now based on ubuntu 24.04 LTS (noble)
• The teku vc subcommand fails when no validator key source is provided. In order to run a validator client, one of the following options must be set:
  --validator-keys, --validators-external-signer-url or --validator-api-enabled
• Updated dependencies.

Bug Fixes

• Fixed performance degradation introduced in 24.4.0 regarding archive state retrieval time.
• Fixed file writer when storing database mode settings to file (related to #8357).

Breaking Changes

• Removed support for the Goerli network --network=goerli.

Additions and Improvements

• Increased the executor queue default maximum size to 40_000 (previously 20_000), and other queues to 10_000 (previously 5_000). If you have custom settings for these queues, check to ensure they're still required.
• Added peers_direction_current libp2p metric to track the number of peers by direction (inbound and outbound).
• Deposit tree snapshots will be loaded from database as a default unless custom snapshot has been provided.
• Added hidden option --Xdeposit-contract-logs-syncing-enabled to allow disabling the syncing of the deposit contract logs from the EL. This is useful when running a non-validating node. It is advisable to be used alongside with --Xeth1-missing-deposits-event-logging-enabled=false to avoid unnecessary logging of missing deposits.
• Updated the bootnodes for Chiado and Gnosis networks.
• Added hidden option --Xp2p-dumps-to-file-enabled to enable saving p2p dumps to file.
• Consensus layer (CL) and execution layer (EL) clients' information will be appended to the validator graffiti. Check documentation for the available configuration options.
