-##### Features
+##### Limitations
 
-- The `time.Time` and `time.Duration` types are handled natively. About `time.Time`, the encoder doesn't invoke the `MarshalJSON`/`MarshalText` methods, but use `time.AppendFormat` instead, and write the output to the stream. Regarding `time.Duration`, it isn't necessary to implements the `json.Marshaler` or `encoding.TextMarshaler` interfaces on a custom wrapper type, the encoder uses the result of one of the methods `Minutes`, `Seconds`, `Nanoseconds` or `String`, based on the duration format configured.
+- The JSON returned by the `MarshalJSON` method of types implementing the `json.Marshaler` interface is neither validated nor compacted.
