 # 3.3.0-unreleased
 - **Breaking change:** [DAP] Several signatures in DAP debug adapter classes have been updated to use `Uri`s where they previously used `String path`s. This is to support communicating with the DAP client using URIs instead of file paths. URIs may be used only when the client sets the custom `supportsDartUris` client capability during initialization.
+- Updated `package:dap` version to 1.2.0.
 
 # 3.2.1
 - Adding `unified_analytics` as a dependency and added static method `DevToolsUtils.initializeAnalytics` to create analytics instance for DevTools.

+## 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.
+
 ## 1.1.0
 
 - Updated all generated classes using the latest published version of the DAP spec.
