@@ -22,6 +22,12 @@ HEAD
* Added `JsonDocument::operator[]`
* Added `ARDUINOJSON_TAB` to configure the indentation character
* Reduced the size of the pretty JSON serializer
* Added `add()`, `createNestedArray()` and `createNestedObject()` to `JsonVariant`
* `JsonVariant` automatically promotes to `JsonObject` or `JsonArray` on write.
Calling `JsonVariant::to<T>()` is not required anymore.
* `JsonDocument` now support the same operations as `JsonVariant`.
Calling `JsonDocument::as<T>()` is not required anymore.
* Fixed example `JsonHttpClient.ino`
