5 | [ this is a template for a new perldelta file. Any text flagged as | |
6 | XXX needs to be processed before release. ] | |
7 | ||
8 | perldelta - what is new for perl v5.13.11 | |
9 | ||
10 | =head1 DESCRIPTION | |
11 | ||
12 | This document describes differences between the 5.13.10 release and | |
13 | the 5.13.11 release. | |
14 | ||
15 | If you are upgrading from an earlier release such as 5.13.9, first read | |
16 | L<perl5139delta>, which describes differences between 5.13.9 and | |
17 | 5.13.10. | |
18 | ||
19 | =head1 Notice | |
20 | ||
21 | XXX Any important notices here | |
22 | ||
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. | |
28 | ||
29 | [ List each enhancement as a =head2 entry ] | |
30 | ||
31 | =head1 Security | |
32 | ||
33 | XXX Any security-related notices go here. In particular, any security | |
34 | vulnerabilities closed should be noted here rather than in the | |
35 | L</Selected Bug Fixes> section. | |
36 | ||
37 | [ List each security issue as a =head2 entry ] | |
38 | ||
39 | =head1 Incompatible Changes | |
40 | ||
41 | XXX For a release on a stable branch, this section aspires to be: | |
42 | ||
43 | There are no changes intentionally incompatible with 5.XXX.XXX. If any | |
44 | exist, they are bugs and reports are welcome. | |
45 | ||
46 | [ List each incompatible change as a =head2 entry ] | |
47 | ||
48 | =head1 Deprecations | |
49 | ||
50 | XXX Any deprecated features, syntax, modules etc. should be listed here. | |
51 | In particular, deprecated modules should be listed here even if they are | |
52 | listed as an updated module in the L</Modules and Pragmata> section. | |
53 | ||
54 | [ List each deprecation as a =head2 entry ] | |
55 | ||
56 | =head1 Performance Enhancements | |
57 | ||
58 | XXX Changes which enhance performance without changing behaviour go here. There | |
59 | may well be none in a stable release. | |

75 | following sections using F<Porting/corelist-perldelta.pl>, which prints stub | |
76 | entries to STDOUT. Results can be pasted in place of the '=head2' entries | |
77 | below. A paragraph summary for important changes should then be added by hand. | |
78 | In an ideal world, dual-life modules would have a F<Changes> file that could be | |

470 | ||
471 | If you find what you think is a bug, you might check the articles | |
472 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
473 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
474 | information at http://www.perl.org/ , the Perl Home Page. | |
475 | ||
476 | If you believe you have an unreported bug, please run the L<perlbug> | |
477 | program included with your release. Be sure to trim your bug down | |
478 | to a tiny but sufficient test case. Your bug report, along with the | |
479 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
480 | analysed by the Perl porting team. | |
481 | ||
482 | If the bug you are reporting has security implications, which make it | |
483 | inappropriate to send to a publicly archived mailing list, then please send | |
484 | it to perl5-security-report@perl.org. This points to a closed subscription | |
485 | unarchived mailing list, which includes all the core committers, who be able | |
486 | to help assess the impact of issues, figure out a resolution, and help | |
487 | co-ordinate the release of patches to mitigate or fix the problem across all | |
488 | platforms on which Perl is supported. Please only use this address for | |
489 | security issues in the Perl core, not for modules independently | |
490 | distributed on CPAN. | |
