+  - Requires V15 metadata on the connected chain
+- feat: add `useRcBlockFormat` query parameter for RC block response formatting ([#1872](https://github.com/paritytech/substrate-api-sidecar/pull/1872)) ([59b88c9](https://github.com/paritytech/substrate-api-sidecar/commit/59b88c9))
+  - When `useRcBlock=true` and `useRcBlockFormat=object`, wraps response in an object containing `rcBlock` info and `parachainDataPerBlock` array
