+- Add `showToUser` field to `DebugAdapterException` to specify which errors should be shown to users.
+
 ## 1.2.0
 
 - Added `DartInitializeRequestArguments`, a subclass of `InitializeRequestArguments` that supports a custom flag `supportsDartUris` for informing the debug adapter that the client supports using URIs in places that might usually be file paths (such as `stackTraceRequest`). Setting this flag indicates that the client supports `file:` URIs _and also_ any custom-scheme URIs whose content can be provided by the analysis server from the matching Dart SDK.
