5 | perldelta - what is new for perl v5.13.2 |
6 | |
7 | =head1 DESCRIPTION |
8 | |
9 | This document describes differences between the 5.13.2 release and |
10 | the 5.13.1 release. |
11 | |
12 | If you are upgrading from an earlier release such as 5.10, first read |
13 | L<perl5120delta>, which describes differences between 5.10 and |
14 | 5.12. |

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

136 | Overloading now works properly in conjunction with tied variables. What |
137 | formerly happened was that most ops checked their arguments for overloading |
138 | I<before> checking for magic, so for example an overloaded object returned |
139 | by a tied array access would usually be treated as not overloaded |
140 | (RT #57012). |

230 | =head1 Reporting Bugs |
231 | |
232 | If you find what you think is a bug, you might check the articles |
233 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
234 | bug database at http://rt.perl.org/perlbug/ . There may also be |
235 | information at http://www.perl.org/ , the Perl Home Page. |
236 | |
237 | If you believe you have an unreported bug, please run the B<perlbug> |
238 | program included with your release. Be sure to trim your bug down |
239 | to a tiny but sufficient test case. Your bug report, along with the |
240 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
241 | analysed by the Perl porting team. |
242 | |
243 | If the bug you are reporting has security implications, which make it |
244 | inappropriate to send to a publicly archived mailing list, then please send |
245 | it to perl5-security-report@perl.org. This points to a closed subscription |
246 | unarchived mailing list, which includes all the core committers, who be able |
247 | to help assess the impact of issues, figure out a resolution, and help |
248 | co-ordinate the release of patches to mitigate or fix the problem across all |
249 | platforms on which Perl is supported. Please only use this address for |
250 | security issues in the Perl core, not for modules independently |
251 | distributed on CPAN. |
