+
+        Refactor FormData and Blob for better support of Blobs synthesized by BlobBuilder.
+        https://bugs.webkit.org/show_bug.cgi?id=39083
+
+        - Introduces a new class BlobItem as a basic component of Blob and
+          FormData and makes Blob as a collection of BlobItems.
+        - File would become a special type of Blob that contains only one
+          FileBlobItem.
+        - Makes FormDataElement a wrapper of BlobItem (as a transient
+          solution).
+        - Fix the dependency violation in FormData so that the files under
+          platform/ do not include any html/ files.
+
+        The patch doesn't support the latest File API changes (e.g. type,
+        url and slice's type parameters) and should not change any of its
+        existing behaviors.
+
+        The existing tests should be able to be used for regression.
