v6.12.0
### 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.
### Changed
- 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."
v6.11.0 #### Added - The `queryLedgerState/stakePools` query now take an optional `includeStake: bool` parameter. When provided and set to `true`, each stake pool result will include an additional `stake` field with its current absolute live stake (reflecting its governance power). - A new query [`queryLedgerState/delegateRepresentatives`] to fetch all registered (and pre-defined) DReps, alongside their metadata and live stake. In a similar fashion to many other queries, DReps can be filtered using `keys` or `scripts` credentials in the query parameters. When both are omitted, all representatives are returned. #### Changed - The dual container image now ships with `cardano-node==10.1.4` #### Removed - N/A
v6.10.0 #### Added - ![TypeScript][] The `ConnectionConfig` can now take an optional `address` object, so that URL with paths can be provided instead of only host/port; allowing for more flexible connection options. - New ledger-state query `ledgerState/dump` which dumps the **ENTIRE** ledger-state as base16-encoded CBOR. That query is mostly for advanced used only, and spits out **a lot** of data. Use only if you know what you're doing. #### Changed - N/A #### Removed - N/A
v6.9.0
#### Added
- Integrate `cardano-node==10.1.2` and associated dependencies.
- New transaction submission / evaluation errors:
- [`EmptyTreasuryWithdrawal`](https://ogmios.dev/mini-protocols/local-tx-submission#schema-3168/EmptyTreasuryWithdrawal) (`code=3168`) triggered when a transaction contains a governance proposal with an empty treasury withdrawal.
- [`UnexpectedMempoolError`](https://ogmios.dev/mini-protocols/local-tx-submission#schema-3997/UnexpectedMempoolError) (`code=3997`) triggered when a transaction is rejected due to custom arbitrary rules that prevented it from entering the mempool.
#### Changed
- N/A
#### Removed
- N/A
v6.8.0 #### Added - Integrate `cardano-node==9.2.0` and associated dependencies. - Add new ledger-state query: `queryLedgerState/governanceProposals` to retrieve currently active governance proposals and their ratification state (i.e. ongoig votes). #### Changed - Fix automatic transaction upgrade to NOT change underlying binary format during upgrade. The previous implementation would on some occasions alter the serialized form, thus causing transaction hash to change and invalidating all signatures on it. The new approach does always preserve binary serialisation, but as a result, makes more scenario not translatable (e.g. trying to translate a multi-asset UTxOs containing a 0 quantity is impossible when targetting Conway). - ![TypeScript][] Fix JSON deserialization of metadata on web platforms. #### Removed - N/A
