43 | This feature was deprecated in Perl 5.14, and has now been removed. |
44 | The CPAN module L<Unicode::Casing> provides better functionality without | |
45 | the drawbacks that this feature had, as are detailed in the 5.14 | |
46 | documentation: | |
47 | L<http://perldoc.perl.org/5.14.0/perlunicode.html#User-Defined-Case-Mappings-%28for-serious-hackers-only%29> | |

49 | =head2 XSUBs are now 'static' |
50 | ||
51 | XSUB C functions are now 'static', that is, they are not visible from | |
52 | outside the compilation unit. For the exceedingly rare case where | |
53 | this is not desired, a new public macro C<XS_EXTERNAL(name)> can be | |
54 | used in place of C<XS(name)>. C<ExtUtils::ParseXS> (C<xsubpp>) | |
55 | can be made to declare XSUBs with C<XS_EXTERNAL> using the | |
56 | C<EXPORT_XSUB_SYMBOLS> keyword, see L<perlxs> for details. | |

34dc2ec0 | 391 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
44691e6f AB |
392 | bug database at http://rt.perl.org/perlbug/ . There may also be |
393 | information at http://www.perl.org/ , the Perl Home Page. | |
394 | ||
395 | If you believe you have an unreported bug, please run the L<perlbug> | |
396 | program included with your release. Be sure to trim your bug down | |
397 | to a tiny but sufficient test case. Your bug report, along with the | |
398 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
399 | analysed by the Perl porting team. | |
400 | ||
401 | If the bug you are reporting has security implications, which make it | |
402 | inappropriate to send to a publicly archived mailing list, then please send | |
34dc2ec0 | 403 | it to perl5-security-report@perl.org. This points to a closed subscription |
