We are excited to release v0.12.0 of Charon, it adds a bunch of new features and client improvements! It is a non-urgent release and is backwards-compatible with v0.11.0 and v0.10.0. The most notable addition is support for Sync Committee Contributions (or sync committee aggregations), the final validator client duty to be implemented.
Notable features:
- #1360 introduces version v1.4 of the cluster definition adding support for a creator to set up a cluster who is not part of the operators.
- #1406 removes the need to run the loki docker driver in docker-compose by sending logs directly to loki if enabled.
- #1450 improves support for debugging QBFT consensus by providing an endpoint to download recent messages (similar to pprof).
Note that since this release is backwards compatible, no upgrade coordination is required between operators in a cluster. Each operator can merely upgrade on their own. As long as threshold nodes (
m of n) are always up and running, no attestations will be missed.
