+version 1.3 (2011/08/07)
+- New commands \resettocdepth and \resetsecnumdepth
+  used for resetting to previous values of the tocdepth
+  and secnumdepth counters (using a stack-based approach).
+  With optional star argument can reset to the original
+  `max' values.
+
+- Bug fix that resets "tocdepth" to its original value after
+  the \tableofcontents -- els it will adversely affect
+  subsequent List of Figures/Tables (or cause no harm,
+  either way).
