Breaking Changes

@​angular/cli

• The ng commands will no longer automatically detect and use cnpm as the package manager. As an alternative use the .npmrc file to ensure npm uses the cnpm registry.

@​angular/build

• • TypeScript versions older than 5.9 are no longer supported.
• The javascriptEnabled option for Less is no longer supported. Projects relying on inline JavaScript within Less files will need to refactor their stylesheets to remove this dependency.
