 # @digitalbazaar/http-client ChangeLog
 
+## 1.2.0 - 2021-07-xx
+
+### Added
+- Ensure that body parsing will occur for JSON content types
+  when individual method functions (e.g., `get`, `post`) are
+  not used (e.g., `httpClient(url, {method: 'get'}`). Body
+  parsing can be disabled by passing the `parseBody` option
+  set to `false`.
