 ### Added
 
+- Added `WithStatus` event option to set Span status at the same time when call RecordError. (#1677)
 - Added `resource.Default()` for use with meter and tracer providers. (#1507)
 - `AttributePerEventCountLimit` and `AttributePerLinkCountLimit` for `SpanLimits`. (#1535)
 - Added `Keys()` method to `propagation.TextMapCarrier` and `propagation.HeaderCarrier` to adapt `http.Header` to this interface. (#1544)
