-This version enables *Hot Module Replacement* feature in NativeScript Angular projects by default.
-There is no need to manually accept *hot* changes and you could safely remove the `module["hot"]` code inside your entry module.
+So far it was required to add a snippet to enable HMR. With this release, you have to __remove__ any previous `module["hot"]` related code so HMR can work out of the box.
+
+However, if you want to continue handling *hot* changes manually, follow [these](https://github.com/NativeScript/nativescript-angular/wiki/NativeScript-5.2-HMR-with-Angular#how-to-manually-enable-hmr-in-nativescript-angular-projects-with-n-52) instructions.
