48 | =head2 C<(?[...])> operators now follow standard Perl precedence |
49 | ||
50 | This experimental feature allows set operations in regular expression | |
51 | patterns. Prior to this, the intersection operator had the same | |
52 | precedence as the other binary operators. Now it has higher precedence. | |
53 | This could lead to different outcomes than existing code expects (though | |
54 | the documentation has always noted that this change might happen, | |
55 | recommending fully parenthesizing the expressions). See | |
56 | L<perlrecharclass/Extended Bracketed Character Classes>. | |

66 | The following modules will be removed from the core distribution in a |
67 | future release, and will at that time need to be installed from CPAN. | |
68 | Distributions on CPAN which require these modules will need to list them as | |
69 | prerequisites. | |
cd7bac54 | 70 | |
a9c3e753 S |
71 | The core versions of these modules will now issue C<"deprecated">-category |
72 | warnings to alert you to this fact. To silence these deprecation warnings, | |
73 | install the modules in question from CPAN. | |
541e1e0d | 74 | |
a9c3e753 S |
75 | Note that these are (with rare exceptions) fine modules that you are encouraged |
76 | to continue to use. Their disinclusion from core primarily hinges on their | |
77 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
78 | not usually on concerns over their design. | |

462 | Core perl now works on this EBCDIC platform. Early perls also worked, | |
463 | but, even though support wasn't officially withdrawn, recent perls would | |
464 | not compile and run well. Perl v5.20 would work, but had many bugs | |
465 | which have now been fixed. Many CPAN modules that ship with Perl still | |
466 | fail tests, including Pod::Simple. However the version of Pod::Simple | |
467 | currently on CPAN should work; it was fixed too late to include in | |
468 | Perl v5.22. Work is under way to fix many of the still-broken CPAN | |
469 | modules, which likely will be installed on CPAN when completed, so that | |
470 | you may not have to wait until v5.24 to get a working version. | |

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

640 | If the bug you are reporting has security implications, which make it | |

641 | inappropriate to send to a publicly archived mailing list, then please send it |
642 | to perl5-security-report@perl.org. This points to a closed subscription | |
643 | unarchived mailing list, which includes all the core committers, who will be | |
644 | able to help assess the impact of issues, figure out a resolution, and help | |
