 ## Bug Fixes
 
-- Check structural equality of diff results in `QueryInfo#setDiff` instead of reference equality. <br/>
-  [@benjamn](https://github.com/benjamn) in [#6891](https://github.com/apollographql/apollo-client/pull/6891)
-
 - Use `options.nextFetchPolicy` internally to restore original `FetchPolicy` after polling with `fetchPolicy: "network-only"`, so that polling does not interfere with normal query watching. <br/>
