Angular 2 is now supported by Sentry for error tracking through their browser JavaScript SDK, including full support for use with TypeScript. The process involves installing the sentry/raven-js package and configuring SystemJS to locate it. A custom ErrorHandler is declared and initiated in the NgModule to capture exceptions and send them to Sentry. Additionally, the Raven.js project now provides a TypeScript language declaration file for static analysis and supports Source Maps, allowing developers to see their original code in error stack traces.
