## Added
- Integration with `cardano-node==8.5.0`. This adds new elements to the Conway era.
- New transaction certificates: `DelegateRepresentativeRegistration`, `DelegateRepresentativeRetirement`, `ConstitutionalCommitteeHotKeyRegistration` and `ConstitutionalCommitteeRetirement`.
- A new governance action `Information`, empty.
- New transaction submission errors: `ForbiddenWithdrawal`, `CredentialDepositMismatch`, `DRepAlreadyRegistered`, `DRepNotRegistered` and `UnknownConstitutionalCommitteeMember`
## Changed
- Integration with `cardano-node==8.5.0`. This introduces a few breaking-change in the Conway era:
- The `DelegateRepresentative` schema has changed to now be a JSON `object` in all cases, with at least a field `type` to discriminate over it. Abstain and NoConfidence delegate representatives have no other fields.
- The stake pool operator id is now always included in the `GovernanceVoter` schema.
- The `ScriptExecutionFailure<MissingScripts>` schema now includes a `data.missingScripts` field for debugging.
- The `SubmitTransactionFailure<UnauthorizedVote>` has been changed to `SubmitTransactionFailure<UnauthorizedVotes>` and now contains a list of unauthorized voters.
- Fixed `inputSource` being set on Byron transactions instead of `spends`.
- Now conditionally include Byron's cbor bytes like for other eras (`--include-transaction-cbor`).
- Fixed transaction metadata's objects being encoded as lists of singletons in the JSON encoding. Now properly encoded as objects.
