+*   The comparison between `Relation` and `CollectionProxy` should be consistent.
+
+    Example:
+
+        author.posts == Post.where(author_id: author.id)
+        # => true
+        Post.where(author_id: author.id) == author.posts
+        # => true
+
+    Fixes #13506.

+*   Calling `delete_all` on an unloaded `CollectionProxy` no longer
+    generates a SQL statement containing each id of the collection:
+
+    Before:
+
+        DELETE FROM `model` WHERE `model`.`parent_id` = 1
+        AND `model`.`id` IN (1, 2, 3...)
+
+    After:
+
+        DELETE FROM `model` WHERE `model`.`parent_id` = 1
+
+    *Eileen M. Uchitelle*, *Aaron Patterson*
