+* [feature] Added support for limited-use tokens with Firebase App Check.
+  These limited-use tokens are required for an upcoming optional feature called
+  _replay protection_. We recommend
+  [enabling the usage of limited-use tokens](https://firebase.google.com/docs/ai-logic/app-check)
+  now so that when replay protection becomes available, you can enable it sooner
+  because more of your users will be on versions of your app that send limited-use tokens.
