15 | If you are upgrading from an earlier release such as 5.13.1, first read |
16 | L<perl5132delta>, which describes differences between 5.13.1 and | |
17 | 5.13.2. | |

23 | =head1 Core Enhancements |
24 | ||
25 | XXX New core language features go here. Summarise user-visible core language | |
26 | enhancements. Particularly prominent performance optimisations could go | |
27 | here, but most should go in the L</Performance Enhancements> section. | |

16036bcd | 32 | |
63098191 KW |
33 | C<\N{}> and C<charnames::vianame> now know about the abbreviated character |
34 | names listed by Unicode, such as NBSP, SHY, LRO, ZWJ, etc., as well as all the | |
35 | customary abbreviations for the C0 and C1 control characters (such as ACK, BEL, | |
36 | CAN, etc.), as well as a few new variants in common usage of some C1 full | |
37 | names. | |
16036bcd KW |
38 | |
39 | In the past, it was ineffective to override one of Perl's abbreviations with | |
40 | your own custom alias. Now it works. | |
41 | ||
232cbbee | 42 | And you can create a custom alias directly to the ordinal of a character, known |
8f3c3cf1 | 43 | by C<\N{...}>, C<charnames::vianame()>, and C<charnames::viacode()>. |
232cbbee KW |
44 | Previously, an alias had to be to an official Unicode character name. This |
45 | made it impossible to create an alias for a code point that had no name, | |
46 | such as the ones reserved for private use. So this change allows you to make | |
47 | more effective use of private use characters. Only if there is no official | |
48 | name will C<charnames::viacode()> return your custom one. | |
49 | ||
50 | See L<charnames> for details on all these changes. | |

79 | =head2 \400 - \777 |
80 | ||
81 | Use of C<\400> - C<\777> in regexes in certain circumstances has given different, | |
82 | anomalous behavior than their use in all other double-quotish contexts. Since | |
83 | 5.10.1, a deprecated warning message has been raised when this happens. Now, | |
84 | all double-quotish contexts have the same behavior, namely to be equivalent to | |
85 | C<\x{100}> - C<\x{1FF}>, with no deprecation warning. Use of these values in the | |
86 | command line option C<"-0"> retains the current meaning to slurp input files | |
87 | whole; previously, this was documented only for C<"-0777">. | |

97 | =head2 Omitting a space between regular expression and subsequent word |
98 | ||
99 | Omitting a space between a regex pattern or pattern modifiers and the | |
100 | following word is deprecated. Deprecation for regular expression matches | |
101 | was added in Perl 5.13.2. In this release, the deprecation is extended | |
102 | to regular expression substitutions. For example, | |
103 | C<< s/foo/bar/sand $bar >> will still be parsed as | |
104 | C<< s/foo/bar/s and $bar >> but will issue a warning. | |
105 | ||
106 | =head2 Deprecation warning added for deprecated-in-core .pl libs | |
107 | ||
108 | This is a mandatory warning, not obeying -X or lexical warning bits. | |
109 | The warning is modelled on that supplied by deprecate.pm for | |
110 | deprecated-in-core .pm libraries. It points to the specific CPAN | |
111 | distribution that contains the .pl libraries. The CPAN version, of | |
112 | course, does not generate the warning. (0111154) | |

689 | =head1 Reporting Bugs |
690 | ||
691 | If you find what you think is a bug, you might check the articles | |
692 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
693 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
694 | information at http://www.perl.org/ , the Perl Home Page. | |
695 | ||
696 | If you believe you have an unreported bug, please run the B<perlbug> | |
697 | program included with your release. Be sure to trim your bug down | |
698 | to a tiny but sufficient test case. Your bug report, along with the | |
699 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
700 | analysed by the Perl porting team. | |
701 | ||
702 | If the bug you are reporting has security implications, which make it | |
703 | inappropriate to send to a publicly archived mailing list, then please send | |
704 | it to perl5-security-report@perl.org. This points to a closed subscription | |
705 | unarchived mailing list, which includes all the core committers, who be able | |
706 | to help assess the impact of issues, figure out a resolution, and help | |
707 | co-ordinate the release of patches to mitigate or fix the problem across all | |
708 | platforms on which Perl is supported. Please only use this address for | |
709 | security issues in the Perl core, not for modules independently | |
710 | distributed on CPAN. | |
