 !!! warning "IMPORTANT CHANGES TO RATINGS IN KOMETA 2.0.3"
 
-    As part of an overhaul of the Ratings default file introduced in 2.0.3, some changes have been made that makes life easier for the user:
+    A new way to apply Ratings overlays has been released as part of Kometa 2.0.3,
 
-    Kometa will automatically fetch the live rating from the selected source (TMDb, IMDb, Trakt via MDBList, etc.) during the Overlays run. This means that **users no longer have to run Mass Rating Update operations to update the Plex ratings**. In effect, this detaches Plex's ratings system from the Ratings overlays.
+    This new system allows the rating to be applied to posters without having to first run Operations to override Plex's in-built ratings slots.
+
+    This is an opt-in feature, any existing configs will continue to work.
+
+    We **strongly** advise that you read [this blog post](https://blog.kometa.wiki/en/latest/) which goes into more detail on the changes and what they mean for you.
 
-    In addition, Kometa will automatically select the best image to use based on the selected rating source that you have chosen. For example, if you define `rating1: imdb` then Kometa will automatically make the image for that rating `imdb`. **You no longer have to specify `ratingX_image` unless you want to override Kometa's default image selection.**
