In particular, it does not include the names of +the (very much appreciated) contributors who reported issues to the Perl bug +tracker. + +Many of the changes included in this version originated in the CPAN modules +included in Perl's core.

There may also be information at +L , the Perl Home Page. + +If you believe you have an unreported bug, please run the L program +included with your release. Be sure to trim your bug down to a tiny but +sufficient test case.
