52 | =head2 Module removals |
53 | ||
54 | XXX Remove this section if inapplicable. | |
55 | ||
56 | The following modules will be removed from the core distribution in a | |
57 | future release, and will at that time need to be installed from CPAN. | |
58 | Distributions on CPAN which require these modules will need to list them as | |
59 | prerequisites. | |
60 | ||
61 | The core versions of these modules will now issue C<"deprecated">-category | |
62 | warnings to alert you to this fact. To silence these deprecation warnings, | |
63 | install the modules in question from CPAN. | |
64 | ||
65 | Note that these are (with rare exceptions) fine modules that you are encouraged | |
66 | to continue to use. Their disinclusion from core primarily hinges on their | |
67 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
68 | not usually on concerns over their design. | |

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

396 | |
397 | If the bug you are reporting has security implications, which make it | |
e08634c5 SH |
398 | inappropriate to send to a publicly archived mailing list, then please send it |
399 | to perl5-security-report@perl.org. This points to a closed subscription | |
400 | unarchived mailing list, which includes all the core committers, who will be | |
401 | able to help assess the impact of issues, figure out a resolution, and help | |
