 These release notes cover changes to the [Extensibility API for Web Developers](/apidocs-mxsdk/apidocs/extensibility-api/).
 
+## Version 11.3.0
+
+* We introduced a new Version Control API under studioPro.ui.versionControl, which allows you to display version control information about the current version control system, branch, and last commit in Studio Pro. For more information, see [Version Control API](/apidocs/web-extensibility-api-11/version-control-api/).
+* Users can use an option in the preferences menu to enable extension development without using the --enable-extension-development feature flag. It requires a restart of Studio Pro.
+* We introduced a new Message Passing API under studioPro.ui.messagePassing, to pass information between different active contexts within an extension. This API supports two communication patterns: request-reply and message broadcasting. For more information, see [Communicaton Between Views API](/apidocs-mxsdk/apidocs/web-extensibility-api-11/command-api/).
