3 | perldelta - what is new for perl v5.11.4 |
4 | |
5 | =head1 DESCRIPTION |
6 | |
7 | This document describes differences between the 5.11.3 release and |
8 | the 5.11.4 release. |
9 | |
10 | If you are upgrading from an earlier release such as 5.11.2, first read |
11 | L<perl5113delta>, which describes differences between 5.11.2 and |
12 | 5.11.3. |

14 | =head1 Notice |
15 | |
16 | XXX Any important notices here |
17 | |
18 | =head1 Incompatible Changes |
19 | |
20 | XXX For a release on a stable branch, this section aspires to be: |
21 | |
22 | There are no changes intentionally incompatible with 5.XXX.XXX. If any |
23 | exist, they are bugs and reports are welcome. |
24 | |
25 | |
26 | =head1 Core Enhancements |
27 | |
28 | XXX New core language features go here. Summarise user-visible core language |
29 | enhancements. Particularly prominent performance optimisations could go |
30 | here, but most should go in the L</Performance Enhancements> section. |
31 | |
32 | =head1 New Platforms |
33 | |
34 | XXX List any platforms that this version of perl compiles on, that previous |
35 | versions did not. These will either be enabled by new files in the F<hints/> |
36 | directories, or new subdirectories and F<README> files at the top level of the |
37 | source tree. |
38 | |
39 | =head1 Modules and Pragmata |
40 | |
41 | XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/> |
42 | go here. If Module::CoreList is updated, generate an initial draft of the |
43 | following sections using F<Porting/corelist-perldelta.pl>, which prints stub |
44 | entries to STDOUT. Results can be pasted in place of the '=head2' entries |
45 | below. A paragraph summary for important changes should then be added by hand. |
46 | In an ideal world, dual-life modules would have a F<Changes> file that could be |
47 | cribbed. |

142 | =item New warning category C<illegalproto> |
e06a4ec4 |
143 | |
cabbd591 |
144 | The two warnings : |
145 | |
146 | Illegal character in prototype for %s : %s |
147 | Prototype after '%c' for %s : %s |
148 | |
149 | have been moved from the C<syntax> top-level warnings category into a new |
150 | first-level category, C<illegalproto>. These two warnings are currently the |
151 | only ones emitted during parsing of an invalid/illegal prototype, so one |
152 | can now do |
153 | |
154 | no warnings 'illegalproto'; |
155 | |
156 | to suppress only those, but not other syntax-related warnings. Warnings where |
157 | prototypes are changed, ignored, or not met are still in the C<prototype> |
158 | category as before. (Matt S. Trout) |

160 | =item lvalue attribute ignored after the subroutine has been defined |
161 | |
162 | This new warning is issued when one attempts to mark a subroutine as |
163 | lvalue after it has been defined. |

240 | =head1 Reporting Bugs |
241 | |
242 | If you find what you think is a bug, you might check the articles |
243 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
244 | bug database at http://rt.perl.org/perlbug/ . There may also be |
245 | information at http://www.perl.org/ , the Perl Home Page. |
246 | |
247 | If you believe you have an unreported bug, please run the B<perlbug> |
248 | program included with your release. Be sure to trim your bug down |
249 | to a tiny but sufficient test case. Your bug report, along with the |
250 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
251 | analysed by the Perl porting team. |
252 | |
253 | If the bug you are reporting has security implications, which make it |
254 | inappropriate to send to a publicly archived mailing list, then please send |
255 | it to perl5-security-report@perl.org. This points to a closed subscription |
256 | unarchived mailing list, which includes all the core committers, who be able |
257 | to help assess the impact of issues, figure out a resolution, and help |
258 | co-ordinate the release of patches to mitigate or fix the problem across all |
259 | platforms on which Perl is supported. Please only use this address for |
260 | security issues in the Perl core, not for modules independently |
261 | distributed on CPAN. |
