v1.0.0-rc7 - 2024-06-25

Warning

This is the seventh 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-rc7 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.

Legend

✅: All duties succeed in testing
🟡: All duties succeed in testing, except non-penalised aggregation duties
