 # Changelog
 
+## 0.2.0
+
+* Start span within function, not outside. This adds support for delayed and
+  repeated invocations of the wrapped function.
+* Bump OpenTelemetry API dependency to 1.1.0.
+* Include exception message as span error status message instead of using an
+  empty message.
+* Drop support for Elixir 1.11.
+
 ## 0.1.0
 
 * Initial release
