CardanoSolutions/ogmios v6.12.0 on GitHub

Added

Two new ledger-state queries:
- queryLedgerState/nonces: internal node's rolling nonces calculations used in consensus.
- queryLedgerState/operationalCertificates: internal stake pool operational certificates states used in consensus.

The queryLedgerState/rewardAccountSummaries now includes the delegate representative -- a.k.a DRep -- (if any) for each summary under a field delegateRepresentative. The field delegate has also been renamed to stakePool to disambiguate both. Also, the stakePool field is now optional and may be omitted in case where a particular account is only delegated to a DRep. Similarly, the field delegateRepresentative will be ommitted when the account is only delegated to a stake pool.
The queryLedgerState/delegateRepresentatives no longer discards registered DReps that have unregistered but whose stake is still available. This may happen when a DRep is already unregistered, but his stake distribution is still available because still needed to ratify votes on the next epoch boundary. As a consequence, some of the fields for the registered drep summaries are now optional instead of required."
