Updated Modules and Pragmata

  • B::Deparse has been upgraded from version 1.03 to 1.04, to address two regressions in Perl 5.14.0:

    Deparsing of the "glob" operator and its diamond ("<>") form now works again. [perl #90898]

    The presence of subroutines named "::::" or "::::::" no longer causes B::Deparse to hang.

  • Pod::Perldoc has been upgraded from version 3.15_03 to 3.15_04.

    It corrects the search paths on VMS. [perl #90640]

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://rt.perl.org/perlbug/ .  There may also be information at http://www.perl.org/ , 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.

If the bug you are reporting has security implications, which make it inappropriate to send to a publicly archived mailing list, then please send it to perl5-security-report@perl.org. This points to a closed subscription unarchived mailing list, which includes all the core committers, who be able to help assess the impact of issues, figure out a resolution, and help co-ordinate the release of patches to mitigate or fix the problem across all platforms on which Perl is supported. Please only use this address for security issues in the Perl core, not for modules independently distributed on CPAN.
