 ### Enhancements
-* <New feature description> (PR [#????](https://github.com/realm/realm-core/pull/????))
 * It is no longer an error to set a base url for an App with a trailing slash - for example, `https://services.cloud.mongodb.com/` instead of `https://services.cloud.mongodb.com` - before this change that would result in a 404 error from the server ([PR #7791](https://github.com/realm/realm-core/pull/7791)).
 * Performance has been improved for range queries on integers and timestamps. Requires that you use the "BETWEEN" operation in MQL or the Query::between() method when you build the query. (PR [#7785](https://github.com/realm/realm-core/pull/7785))
-* None.
+* Expose `Obj::add_int()` in the bindgen spec. ([PR #7797](https://github.com/realm/realm-core/pull/7797)).
 
 ### Fixed
 * <How do the end-user experience this issue? what was the impact?> ([#????](https://github.com/realm/realm-core/issues/????), since v?.?.?)
