 - [changed] Changed `get()` to only make 1 attempt to reach the backend before
   returning cached data, potentially reducing delays while offline. Previously
   it would make 2 attempts, to work around a backend bug.
+- [changed] Some SDK errors that represent common mistakes (such as permission
+  denied or a missing index) will automatically be logged as a warning in
+  addition to being surfaced via the API.
 
 # 17.1.0
