+Changes From Version 2 To Version 3
+===================================
+
+Version 3 adds a new benchmark, RegExp.  The RegExp benchmark is
+generated by loading 50 of the most popular pages on the web and
+logging all regexp operations performed.  Each operation is given a
+weight that is calculated from an estimate of the popularity of the
+pages where it occurs and the number of times it is executed while
+loading each page.  Finally the literal letters in the data are
+encoded using ROT13 in a way that does not affect how the regexps
+match their input.
