Before the official release candidate, there were 10 beta releases issued for Angular 12. The new features and improvements in Angular 12 include the following as listed below:

A variety of bug fixes also are featured, affecting the compiler, compiler-cli, Bazel build tool, the router, and other parts of Angular. A full list of changes can be found on GitHub. The current Angular 11 line debuted as a production release in November.
