v1.9.1 - 2026-03-06
This is non-urgent but recommended patch release of Charon v1.9.0. This patch removes an unnecessary miss-firing
VC missing validatorsready check. Feedback is welcome and appreciated, please use github issues or discord if you have trouble with this release.Read the rest of the release notes for more:

Compatibility Matrix
This release of Charon is backwards compatible with Charon >= v1.0., though only v1.7. and newer are Fulu-ready.
The below matrix details a combination of beacon node (consensus layer) + validator clients and their corresponding versions the DV Labs 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.

v1.9.0 - 2026-02-24
This is Charon's v1.9.0 release. Feedback is welcome and appreciated, please use github issues or discord if you have trouble with this release.
For perfect backwards compatibility, Charon users on v1.8.2 and older should add the
--feature-set-enable=fetch_only_commidx_0,proposal_timeoutas a flag, orCHARON_FEATURE_SET_ENABLE=fetch_only_commidx_0,proposal_timeoutas an environment variable to their setups before the nodes in the cluster begin to update to v1.9.0. Alternatively, update all of the nodes in the cluster to this version in close succession.Read the rest of the release notes for more:

Promote
proposal_timeoutfeature flag to stableWe have extensively tested the
proposal_timeoutflag in the past months with numerous DV clusters on mainnet. From this version it is considered stable and moved to default-enabled. Clusters running Charon v1.9.0 will have the first QBFT round for proposal duties set at 1.5s (with second round timing out at 3.5s) in comparison to the current of 1.0s (with second round timing out at 3.0s). There is no urgent need to synchronise upgrades between cluster nodes, as the cluster will reach consensus on whichever timeout threshold of nodes agree on.Promote
fetch_only_commidx_0feature flag to stablePost-electra Validator Clients were expected to request data from the beacon node (and hence, the DV) for a hardcoded committee index of 0. However, some clients continued requesting for their specific committee index. This forced Charon to also request the same index from the upstream beacon node(s). Now that this behaviour has been updated in all validator clients supported by Charon, we can promote this opt-in feature flag to stable, reducing the amount of requests we send to a beacon node by up to 64x.
In this issue can be found the list with the minimum required VC version.
Scheduled Duties Cache
This version releases a caching mechanism for validator duties. To save on slow, burdensome requests to a BN, Charon caches them locally. Allowing it to reduce the amount of load on upstream beacon nodes.
Replace operator command
This release adds the ability to directly replace an existing node operator in a cluster, rather than adding, and removing operators sequentially.
