✅ Goodbye to Protractor

✅ Stylish Improvements

• Angular components will now support inline Sass . Previously, Sass was only available in external resources due to the Angular compiler

In the v11.2 release, added support for Tailwind CSS.

• initialize Tailwind to create the tailwind.config.jsin your project.

• Now, teams are ready to start using Tailwind in Angular.
