Changes
       This is just a selected list of some of the more notable changes.  The numbers refer to the Perl repository
       change numbers; see Changes58 (or Changes in Perl 5.8.1).  In addition to these changes, lots of work took
       place in integrating threads, PerlIO, and Unicode; general code cleanup; and last but not least porting to non-
       UNIX lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic, and EBCDIC.

Reporting Bugs
       If you find what you think is a bug, you might check the articles recently posted to the comp.lang.perl.misc
       newsgroup and the perl bug database at http://bugs.perl.org.  There may also be information at
       http://www.perl.com/, the Perl Home Page.

       If you believe you have an unreported bug, please run the perlbug program included with your release.  Be sure
       to trim your bug down to a tiny but sufficient test case.  Your bug report, along with the output of "perl -V",
       will be sent off to perlbugATperl.org to be analysed by the Perl porting team.
