v1.0.0

v1.0.0 - 2024-07-1

This is Charon's first major release!

As detailed by our version compatibility, Charon v1.0.0 is not fully-backwards compatible with v0.x.x releases. Block proposals are not compatible between the versions, so once your cluster begins the upgrade, please upgrade all nodes promptly to ensure readiness for a proposal opportunity should one occur.

Breaking changes

• Full support for beacon spec produceBlockV3 endpoint has been implemented: DutyProposer supports now both blinded and unblinded blocks, while DutyBuilderProposer has been deprecated.
  • This means you should remove the extra validator configuration added during previous versions of charon, consult the prior release to see what flags to remove to default to the lastest version of block proposals.

Migration notes

• Make sure that your validator client of choice supports produceBlockV3, and that you re-enable it by either removing or toggling all the flags we detailed in v0.19.2 release notes:

  • Lodestar: --useProduceBlockV3=true as CLI parameter at startup
  • Lighthouse: --produce-block-v3 as CLI parameter at startup
  • Teku: --Xblock-v3-enabled=true as CLI parameter at startup

• If you run Nimbus as a validator client, make sure to pass --feature-set-enable=json_requests as CLI parameter to charon run at startup

• If you run Teku as a beacon node, add the flag --validators-graffiti-client-append-format=DISABLED to it.

Compatibility Matrix

This matrix details the combination of beacon node + validator clients and their corresponding versions the Obol team have tested with this charon release. More validator and consensus client will be added to this list as they are supported in our automated testing framework.

v1.0.0-rc3

v1.0.0-rc3 - 2024-06-08

Warning

This is the third release candidate for our first major Charon release! Unless you want to test this rc, you should wait until a full v1.0.0 is published and announced.

As detailed by our version compatibility, being a major release, Charon v1.0.0-rc1 is not fully-backwards compatible with v0.x.x releases. Block proposals are not compatible between the versions, so once your cluster begins the upgrade, please upgrade all nodes promptly to ensure readiness for a proposal opportunity should one occur.

Breaking changes

• Full support for beacon spec produceBlockV3 endpoint has been implemented: DutyProposer supports now both blinded and unblinded blocks, while DutyBuilderProposer has been deprecated.
  • This means you should remove the extra validator configuration added during previous versions of charon, consult the prior release to see what flags to remove to default to the lastest version of block proposals.

Compatibility Matrix

This matrix details the combination of beacon node + validator clients and their corresponding versions the Obol team have tested with this charon release. More validator and consensus client will be added to this list as they are supported in our automated testing framework.

v0.19.2

v0.19.2 - 2024-03-07

This release downgrades a dependency to ensure performance at high validator counts, and sets a more recent timestamp for builder API registrations to make validator migration more seamless.

A reminder on Produce Block endpoint V3

The Charon team is working towards supporting the Produce Block V3 endpoint, but in the meantime v0.19.2 will still only support the V2 endpoints.

At the time of releasing not all validator clients default to the new Produce Block V3 endpoint, for those that do, set the following flags on your validator client to ensure your validator asks for v2 blocks until a version of charon supports the v3 endpoint:

Lodestar: --useProduceBlockV3=false as CLI parameter at startup
Lighthouse: --produce-block-v3=false as CLI parameter at startup
Teku: --Xblock-v3-enabled=false as CLI parameter at startup
Nimbus automatically falls back to V2 endpoints

Full Changelog: v0.19.1..v0.19.2

Bug

• MEV rewards sent to addresses configured on the CL + VC, not as specified in Charon's lock file #2770 (#2892)
• Charon timeouts requests to /eth/v2/debug/beacon/states/head #2954

What's Changed

• gomod: downgrade go-eth2-client to v0.19.7 (#2941)

v0.19.1

v0.19.1 - 2024-02-14

This patch release contains fixes for issues identified in Charon's second audit, along with support for the POST variant of /eth/v1/beacon/states/<state_id>/validators, optimized memory footprint when paired with Teku.

A reminder on Produce Block endpoint V3

The Charon team is working towards supporting the Produce Block V3 endpoint, but in the meantime v0.19.2 will still only support the V2 endpoints.

At the time of releasing not all validator clients default to the new Produce Block V3 endpoint, for those that do, set the following flags on your validator client to ensure your validator asks for v2 blocks until a version of charon supports the v3 endpoint:

Lodestar: --useProduceBlockV3=false as CLI parameter at startup
Lighthouse: --produce-block-v3=false as CLI parameter at startup
Teku: --Xblock-v3-enabled=false as CLI parameter at startup
Nimbus automatically falls back to V2 endpoints

Change to Docker tagging policy

Before v0.19.1, the charon:latest Docker tag pointed to the latest commit on main.

To provide a more stable experience, from v0.19.1 onwards we will respect the following Docker tags criteria:

• latest: latest tagged version, i.e. latest stable release
• next: latest commit on main

Full Changelog: v0.19.0..v0.19.1

Feature

• Implement POST get validators endpoint #2840 (#2864)

Bug

• create cluster doesn't error when run in same directory #2851 (#2854)

What's Changed

• *: implement audit fixes (#2821)

v0.19.0

v0.19.0 - 2024-01-15

We are delighted to announce the release of Charon v0.19.0! This release brings bug fixes and improvements to the Charon codebase, and supports running DV clusters on the next Ethereum fork, Dencun.

While this version supports older Ethereum forks, v0.19.0 is the first release to fully support Dencun, so it is not possible to run mixed v0.18.0 and v0.19.0 clusters after the fork.

⚠️ This is an urgent release for Goerli Distributed Validator clusters. Please upgrade before 6:32 UTC on January 17, 2024. Clusters on other networks can wait and observe a smooth fork transition on Goerli first before upgrading before their network's hardfork date. ⚠️

A note on Produce Block endpoint V3

The Charon team is working towards supporting the Produce Block V3 endpoint, but in the meantime v0.19.0 will still only support V2 endpoints.

At the time of releasing not all validator clients support the new Produce Block V3 endpoint, for those that do, set the following flags on your validator client to ensure your validator asks for v2 blocks until a version of charon supports the v3 endpoint:
