- Major rewrite of XS code to permit easier inclusion in core Perl (mostly
written by Father Chrysostomos sprout@cpan.org). XS code is no longer
supported for any Perl < v5.10, although the pure Perl code still works
going back to 5.005_04.
In addition, the version::vpp class is now completely independent and can
be use'd exactly like the base version class. It is still better to use
the base class for compatibility purposes.
