Summary

This high priority release contains important bug-fixes and improvements that we recommend for all users. Importantly, fixes are included for the recent 7-block re-org on mainnet. Fast and widespread adoption of this release will help protect the network from repetition of this event.

This release also contains fixes to increase the chances of getting head votes and producing blocks during degenerate scenarios.

Notable changes include:

• Bug-fix to increase likelihood of block production in degenerate cases (#3188)
• Bug-fix to prevent missed head votes in degenerate cases (#3183)
• Running fork choice before proposing a block (#3168)
• Proposer boost reduced to 40% (#3201)
• Optimisation to lessen impact of backfill resource hogging (#3215)
• Support for the Ropsten Beacon Chain (#3184, #3225)
• Support for the Remote Key Manager API (#3162)
• Various improvements to syncing and networking (#3142, #3153, #3182)
• Bug-fix for HTTP Accept header parsing (#3185)
• Client authentication for Web3Signer (#3170)
• Smaller intermediate images during Docker builds (#3174)
• Fixes for merge testnets (#3165)

Thanks to external contributors @ackintosh, @huitseeker, @zsluedem and @petertdavies. Special shout-out to @tthebst who contributed two important PRs to this release (#3162, #3188).

Ropsten

Use the --network ropsten flag to join the Ropsten testnet.

This release introduces support for the Ropsten Beacon Chain with the updated total terminal difficulty (TTD) value of 1e32. We recommend all Ropsten users running v2.3.0-rc.0 to upgrade to this version before the Ropsten beacon chain genesis (less than 12 hours away, at the time of writing).

Breaking Changes

❗ Database Schema Upgrade ❗

This release contains a backwards-incompatible database schema migration for any network that has undergone "the merge" (see #3157). At the time of writing, this includes Kiln and Kintsugi but excludes Prater and Mainnet. For clarity:

• Prater, Mainnet: users who upgrade to v2.3.0 are able to downgrade to v2.2.x and v2.1.x releases using lighthouse db
• Kiln, Kinstugi: users who upgrade to v2.3.0 are not able to downgrade to any prior release

See the Database Migrations documentation for more information on downgrading.

Docker Base Image

The Docker base image has been updated from Ubuntu 20.04 to Ubuntu 22.04 LTS. Older versions of Docker are unable to run the new image due to an incompatibility, so please ensure that you update your Docker engine past version 20.10.10 (released Oct 2021). Please see #3230 for more information.

Update Priority

This table provides priorities for which classes of users should update particular components.

The Beacon Node may be updated without the Validator Client, however we recommend updating both components.

See Update Priorities for more information about this table.
