+    - H5Dget_chunk_storage_size
+
+      The storage size of a chunk in the file is needed to determine the size
+      of the buffer to be allocated for reading a chunk directly from a file.
+
+      New API function gets the size in bytes currently allocated within a
+      file for a raw data chunk in a dataset.  This function was added to get
+      the chunk size in support of the implementation of H5DOread_chunks, but
+      may also be useful for other purposes.

     - H5DOread_chunk

-      New API function, H5DOread_chunk, corresponding to existing function
