NAME

perldelta - what is new for perl v5.8.0

DESCRIPTION

This document describes differences between the 5.6.0 release and the 5.8.0 release.

Many of the bug fixes in 5.8.0 were already seen in the 5.6.1 maintenance release since the two releases were kept closely coordinated (while 5.8.0 was still called 5.7.something).

Changes that were integrated into the 5.6.1 release are marked [561]. Many of these changes have been further developed since 5.6.1 was released, those are marked [561+].

You can see the list of changes in the 5.6.1 release (both from the 5.005_03 release and the 5.6.0 release) by reading perl561delta.

Highlights In 5.8.0

• Better Unicode support
• New IO Implementation
• New Thread Implementation
• Better Numeric Accuracy
• Safe Signals
• Many New Modules
• More Extensive Regression Testing

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.
