  - Let clients offer a service default idle timeout to the request handler through updateHttpClientConfig, taken only when the handler has none of its own.

3. ### [3.37.0](https://inlinr.com/packages/@smithy/core/releases/3.37.0 "Open this release") [](https://github.com/smithy-lang/smithy-typescript/releases/tag/%40smithy/core%403.37.0 "Read this release where it was published")  
26 Oct 2026

  - Add AbstractRpcV2Protocol, a shared abstract base for the Smithy RPC v2 JSON and CBOR client protocols, deduplicating their request framing and response status handling.
  - Add Smithy RPC v2 JSON protocol support: client protocol and JSON codec in @smithy/core, server protocol in @smithy/server-common, and the snapshot response serializer in @smithy/snapshot-testing.
  - Treat any non-200 response as an error in the Smithy RPC v2 JSON and CBOR client protocols, per the specification. RpcProtocol gains a protected isErrorResponse predicate (default unchanged: status >= 300) that both RPC v2 protocols override to status !== 200.
