+### `0.15.0` — March 25, 2021
+
+###### FIXED
+
+**Unions can now be coerced.** Previously unions created a barrier in coercion such that structs nested inside unions would not have their coercion logic triggered, but this has been fixed.
+
+**Assigning preserves `type` structs.** Previously using the `assign` helper would implicitly convert `type` structs into `object` structs which wasn't expected and confusing, but this has been fixed.
