What’s in this release?

✅ Moving closer to IVY engine 👌

• View Engine is basically deprecated, it will be removed in a future major release

• Current libraries using View Engine will still work with Ivy apps (no work is required by developers), but library authors should start planning to transition to Ivy.

✅ Goodbye to Protractor

• Angular 12 opted to not include protractor in new projects and, instead, provide options with popular 3rd party solutions in the Angular CLI. Angular team currently working with Cypress, WebdriverIO, and TestCafe

✅ Nullish Coalescing

• We can use nullish coalescing in angular components

✅ Stylish Improvements

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

• To enable this feature in your existing applications add
  
  "inlineStyleLanguage": "scss”
  
  to angular.json. Otherwise, it will be available to new projects using SCSS

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

• install the tailwindcss package from npm

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

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

• 👉 Added experimental support for Webpack 5
