 # ChangeLog
 # ---------
 #
+# 2.6   Ability to disable inclusion of patents and citations. This
+#       has the same effect as unchecking the two patents/citations
+#       checkboxes in the Scholar UI, which are checked by default.
+#       Accordingly, the command-line options are --no-patents and
+#       --no-citations.
+#
 # 2.5:  Ability to parse global result attributes. This right now means
 #       only the total number of results as reported by Scholar at the
 #       top of the results pages (e.g. "About 31 results"). Such
