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 perlbug@perl.org to be analysed by the Perl porting team.
