+### API Breaking
+
+* [\#6923](https://github.com/cosmos/ibc-go/pull/6923) The JSON msg api for `VerifyMembershipMsg` and `VerifyNonMembershipMsg` payloads for client contract `SudoMsg` has been updated. The field `path` has been changed to `merkle_path`. This change requires updates to 08-wasm client contracts for integration.
