+Subject: [PATCH 19/29] gatomicarray: Drop volatile qualifier from GAtomicArray
+ API
+
+This is an API break, but it should not affect third party code since
+that code should not be interacting with the `data` member in a way that
+invokes its `volatile` qualifier (such as copying to an intermediate
+variable).
