+## Breaking Changes
+
+### @nguniversal/common
+
+- Inlining of critical CSS is no longer enable by default. Users already on Angular version 12 and have not opted-out from using this feature are encouraged to opt-in using the `inlineCriticalCss` option.
+
+The motivation behind this change is that the package used to parse the CSS has a number of defects which can lead to unactionable error messages when updating to Angular 13 from versions priors to 12. Such errors can be seen in the following issue https://github.com/angular/angular-cli/issues/20760.
