 ## `bytemuck_derive` changelog
 
+## 1.7.0
+
+This primarily relaxes the bounds on a `From` impl.
+
+Previously:
+
+> `impl<T: NoUninit> From<Box<T>> for BoxBytes`
+
+Now:
+
+> `impl<T: ?Sized + sealed::BoxBytesOf> From<Box<T>> for BoxBytes`
+
+All related functions and methods are similarly updated.
+
+We believe this to be backwards compatible with all previous uses,
+and now `BoxBytes` can be converted to/from more types than before.
+
 ## 1.6.0
 
 * This allows `CheckedBitPattern` to be derived for enums with fields.
