+    - The tools library was updated by standardizing the error stack process.
+
+      General sequence is:
+          h5tools_setprogname(PROGRAMNAME);
+          h5tools_setstatus(EXIT_SUCCESS);
+          h5tools_init();
+          ... process the command-line (check for error-stack enable) ...
+          h5tools_error_report();
+          ... (do work) ...
+          h5diff_exit(ret);
+
+      (ADB - 2020/07/20, HDFFV-11066)
+
+    - 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.
+
+      (ADB - 2020/07/20, HDFFV-10897)
+
+    - 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.
+      Adding the exclude-attribute argument will only eclude attributes, with the supplied path,
+      from comparision.
+
+      (ADB - 2020/07/20, HDFFV-5935)
+
+    - h5diff added another level to the verbose argument to print filenames.
+
+      Added verbose level 3 that is level 2 plus the filenames. The levels are:
+          0 : Identical to '-v' or '--verbose'
+          1 : All level 0 information plus one-line attribute status summary
+          2 : All level 1 information plus extended attribute status report
+          3 : All level 2 information plus file names
