12 | This document describes differences between the 5.15.3 release and |
13 | the 5.15.4 release. | |

3432e5a1 SL |
15 | If you are upgrading from an earlier release such as 5.15.3, first read |
16 | L<perl5153delta>, which describes differences between 5.15.3 and | |
17 | 5.15.4. | |

d2006265 | 26 | |
3f728e2e NC |
27 | C<$^X> is now converted to an absolute path on OS X, FreeBSD (without |
28 | needing F</proc> mounted) and Solaris 10 and 11. This augments the | |
29 | previous approach of using F</proc> on Linux, FreeBSD and NetBSD | |
30 | (in all cases, where mounted). | |
31 | ||
32 | This makes relocatable perl installations more useful on these platforms. | |

370 | =head1 Reporting Bugs |
371 | ||
372 | If you find what you think is a bug, you might check the articles | |
34dc2ec0 | 373 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
44691e6f AB |
374 | bug database at http://rt.perl.org/perlbug/ . There may also be |
375 | information at http://www.perl.org/ , the Perl Home Page. | |
376 | ||
377 | If you believe you have an unreported bug, please run the L<perlbug> | |
378 | program included with your release. Be sure to trim your bug down | |
379 | to a tiny but sufficient test case. Your bug report, along with the | |
380 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
381 | analysed by the Perl porting team. | |
382 | ||
383 | If the bug you are reporting has security implications, which make it | |
384 | inappropriate to send to a publicly archived mailing list, then please send | |
34dc2ec0 | 385 | it to perl5-security-report@perl.org. This points to a closed subscription |
b4707b2a FC |
386 | unarchived mailing list, which includes |
387 | all the core committers, who will be able | |
44691e6f AB |
388 | to help assess the impact of issues, figure out a resolution, and help |
389 | co-ordinate the release of patches to mitigate or fix the problem across all | |
34dc2ec0 DM |
390 | platforms on which Perl is supported. Please only use this address for |
391 | security issues in the Perl core, not for modules independently | |
