+    - h5diff fixed a command line parsing error.
+
+        h5diff would ignore the argument to -d (delta) if it is smaller than DBL_EPSILON.
+        The macro H5_DBL_ABS_EQUAL was removed and a direct value comparision was used.

+    - h5diff added a command line option to ignore attributes.
+
+        h5diff would ignore all objects with a supplied path if the exclude-path argument is used.
