2cfe9b50 | 51 | XXX Remove this section if inapplicable. |
eabfc7bc | 52 | |
2cfe9b50 RS |
53 | The following modules will be removed from the core distribution in a |
54 | future release, and will at that time need to be installed from CPAN. | |
55 | Distributions on CPAN which require these modules will need to list them as | |
56 | prerequisites. | |
eabfc7bc | 57 | |
2cfe9b50 RS |
58 | The core versions of these modules will now issue C<"deprecated">-category |
59 | warnings to alert you to this fact. To silence these deprecation warnings, | |
60 | install the modules in question from CPAN. | |
eabfc7bc | 61 | |
2cfe9b50 RS |
62 | Note that these are (with rare exceptions) fine modules that you are encouraged |
63 | to continue to use. Their disinclusion from core primarily hinges on their | |
64 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
65 | not usually on concerns over their design. | |

445 | If the bug you are reporting has security implications, which make it | |
e08634c5 SH |
446 | inappropriate to send to a publicly archived mailing list, then please send it |
447 | to perl5-security-report@perl.org. This points to a closed subscription | |
448 | unarchived mailing list, which includes all the core committers, who will be | |
449 | able to help assess the impact of issues, figure out a resolution, and help | |
f9001595 | 450 | co-ordinate the release of patches to mitigate or fix the problem across all |
