+## 23.0.0-rc2
+
+**This release adds support for Protocol 23**
+
+**Upgrading to this version will trigger a state rebuild. During this process, Horizon will not ingest new ledgers.**
+
+**This release of Horizon requires stellar-core version [23.0.0rc.1](https://github.com/stellar/stellar-core/releases/tag/v23.0.0rc.1) or higher. Older versions of stellar-core are incompatible with this build of Horizon.**
+
+### Breaking Changes
+In Protocol 23, Stellar Core removes in-memory mode and requires on-disk mode (using BucketListDB) for captive core ([5627](https://github.com/stellar/go/pull/5627)). As a result, the following configurations are no longer supported and have been removed:
+- `CAPTIVE_CORE_USE_DB`
+- `DEPRECATED_SQL_LEDGER_STATE`
+
+### Added
+- Update default pubnet captive core configuration to replace Whalestack with Creit Technologies in the quorum set ([5564](https://github.com/stellar/go/pull/5564)).
+- Added 1 new optional string field `destination_muxed_id` in the `asset_balance_changes` section of the `/operations` endpoint which represents the muxed id in the case where an asset is transferred to a muxed account destination ([5715](https://github.com/stellar/go/pull/5715), [5739](https://github.com/stellar/go/pull/5739)). Note that the `destination_muxed_id_type` field was introduced in the `23.0.0-rc1` release, however, the field turned out to be unnecessary and was removed.
+
+### Removed
+
+- The `errorResultXdr` field from the response of the async transaction submission endpoint has been removed ([5737](https://github.com/stellar/go/pull/5737)).
+- The `num_archived_contracts` and `archived_contracts_amount` fields from the `/assets` response have been removed ([5611](https://github.com/stellar/go/pull/5611)).
