10=head1 DESCRIPTION
11
12This document describes differences between the 5.13.10 release and
13the 5.13.11 release.
14
15If you are upgrading from an earlier release such as 5.13.9, first read
16L<perl5139delta>, which describes differences between 5.13.9 and
175.13.10.

21XXX Any important notices here
22
23=head1 Core Enhancements
24
25XXX New core language features go here. Summarise user-visible core language
26enhancements. Particularly prominent performance optimisations could go
27here, but most should go in the L</Performance Enhancements> section.
28
29[ List each enhancement as a =head2 entry ]
30
31=head1 Security
32
33XXX Any security-related notices go here. In particular, any security
34vulnerabilities closed should be noted here rather than in the
35L</Selected Bug Fixes> section.

39=head1 Incompatible Changes
40
41XXX 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
50XXX Any deprecated features, syntax, modules etc. should be listed here.
51In particular, deprecated modules should be listed here even if they are
52listed 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
58XXX Changes which enhance performance without changing behaviour go here. There
59may well be none in a stable release.

74go here. If Module::CoreList is updated, generate an initial draft of the
75following sections using F<Porting/corelist-perldelta.pl>, which prints stub
76entries to STDOUT. Results can be pasted in place of the '=head2' entries
77below. A paragraph summary for important changes should then be added by hand.
78In an ideal world, dual-life modules would have a F<Changes> file that could be
79cribbed.

390=head1 Reporting Bugs
391
392If you find what you think is a bug, you might check the articles
393recently posted to the comp.lang.perl.misc newsgroup and the perl
394bug database at http://rt.perl.org/perlbug/ . There may also be
395information at http://www.perl.org/ , the Perl Home Page.
396
397If you believe you have an unreported bug, please run the L<perlbug>
398program included with your release. Be sure to trim your bug down
399to a tiny but sufficient test case. Your bug report, along with the
400output of C<perl -V>, will be sent off to perlbug@perl.org to be
401analysed by the Perl porting team.
402
403If the bug you are reporting has security implications, which make it
404inappropriate to send to a publicly archived mailing list, then please send
405it to perl5-security-report@perl.org. This points to a closed subscription
406unarchived mailing list, which includes all the core committers, who be able
407to help assess the impact of issues, figure out a resolution, and help
408co-ordinate the release of patches to mitigate or fix the problem across all
409platforms on which Perl is supported. Please only use this address for
410security issues in the Perl core, not for modules independently
411distributed on CPAN.
