## 0.37.0

**`(feat):`** The `additionalBodyParameters` request option (`[String: String]`) is now applied to requests;
previously it was accepted but ignored. Add a new `additionalBodyProperties` request option
(`[String: JSONValue]`) for sending non-string JSON values (booleans, numbers, arrays, objects,
and `null`). Both are merged into the serialized JSON request body using wire-format keys,
override generated fields on collision, and create a JSON body when the endpoint has none
(except GET and HEAD requests, which are still sent without a body);
`additionalBodyProperties` wins when both set the same key. Multipart and raw `Data` bodies are
left unchanged. `JSONValue` now supports string, integer, float, boolean, array, and dictionary
literals.
