on GitHub

Upcoming Breaking Changes

• Docker images are now being published to consensys/teku. The pegasys/teku images will continue to be updated for the next few releases but please update your configuration to use consensys/teku.
• --validators-key-files and --validators-key-password-files have been replaced by --validator-keys. The old arguments will be removed in a future release.

20.11.0

The beacon chain is set to launch with the MainNet genesis state now set. The beacon chain will launch on 1 December 2020 at 12:00:23 UTC.
Teku 20.11.0 is fully production ready and has full support for the beacon chain Mainnet.

Breaking Changes

• REST API endpoint /eth/v1/beacon/pool/attestations now accepts an array of attestations instead of a single attestation.

Additions and Improvements

• Full support for Eth2 MainNet. Genesis state and bootnodes are now configured as part of the --network mainnet option.
• Voluntary exits and slashings submitted via the REST API are now broadcast to the gossip network.
• Added /teku/v1/admin/liveness endpoint which always returns 200 OK to be used to check if the REST API is live.
• Added dependent_root field to attester and block producer duties as well as
  current_duty_dependent_root and previous_duty_dependent_root to the head events to aid validator clients in determining when duties are invalidated by changes in the chain.
• Tightened validation of data from the beacon node in the validator client to ensure blocks and attestations from far future slots are not signed.

Bug Fixes

• Fixed incorrect expected attestation metric.
• Fixed incorrect beacon_previous_correct_validators metrics.
• Fixed race condition during validator startup which could lead to duties not being performed for the first two epochs.
• Provide a human-friendly error message when the --network argument is unknown.
• Provide more human-friendly error messages when invalid options are given to the voluntary-exit subcommand.
• Avoided duplicate epoch processing during block creation.
• Reduce noise from UNKNOWN_PARENT errors when syncing.
• Drop discovery session when a malformed authheadermessage packet is received.
