 # ChangeLog
 # ---------
 #
+# 2.12  Added a JSON export option (author: <nojhan@nojhan.net>).
+#
 # 2.11  The Scholar site seems to have become more picky about the
 #       number of results requested. The default of 20 in scholar.py
 #       could cause HTTP 503 responses. scholar.py now doesn't request
