  16  =head1 Changes
  17  
  18  This is just a selected list of some of the more notable changes.
  19  The numbers refer to the Perl repository change numbers; see
  20  L<Changes58> (or L<Changes> in Perl 5.8.1).  In addition to these
  21  changes, lots of work took place in integrating threads, PerlIO, and
  22  Unicode; general code cleanup; and last but not least porting to
  23  non-UNIX lands such as Win32, VMS, Cygwin, DJGPP, VOS, MacOS Classic,
  24  and EBCDIC.

 217  
 218  If you find what you think is a bug, you might check the articles
 219  recently posted to the comp.lang.perl.misc newsgroup and the perl
 220  bug database at http://bugs.perl.org.  There may also be
 221  information at http://www.perl.com/, the Perl Home Page.

 223  If you believe you have an unreported bug, please run the B<perlbug>
 224  program included with your release.  Be sure to trim your bug down
 225  to a tiny but sufficient test case.  Your bug report, along with the
 226  output of C<perl -V>, will be sent off to perlbug@perl.org to be
 227  analysed by the Perl porting team.
