 ### Added
 
 * `Changeset#extend` to exclude steps from the `#diff` output, this allows
   to filter out timestamp changes prior to updates so that we can avoid
   hitting the database in case of timestamp-only changes. You still can call `.map(:touch)`
   if you want to have `updated_at` refreshed unconditionally (flash-gordon)
+
+## Fixed
+
+* `aggregate` and `combine` works correctly with nested graph options where associations are aliased (solnic)
+* Auto-mapping no longer creates intermediate struct objects for combined relations (which caused massive performance degradation in some cases) (solnic)
+* Aliased associations no longer cause mapping to intermediate structs (solnic)
+
