+=head1 Obituary
+
+It is with great sadness we note that Kip Hampton passed away. Probably

+core contributor to AxKit, ab XML server platform that became an Apache
+Foundation project. He was a frequent speaker in the early days at
+OSCON, and most recently at YAPC::NA in Madison. He was frequently on
+irc.perl.org as `ubu`, generally in the #axkit-dahut community, the
+group responsible for YAPC::NA Asheville in 2011.
+
+Kip and his constant contributions to the community will be greatly missed.
+
+=head1 Acknowledgements
+
+
+Perl 5.25.11 represents approximately 4 weeks of development since Perl 5.25.10
+and contains approximately 4,900 lines of changes across 240 files from 21
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 2,200 lines of changes to 170 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its third decade thanks to a vibrant community
+of users and developers. The following people are known to have contributed the
+improvements that became Perl 5.25.11:
+
+Aaron Crane, Andy Lester, Chris 'BinGOs' Williams, Craig A. Berry, Dave Cross,
+David Golden, David Mitchell, Dominic Hargreaves, H.Merijn Brand, Hugo van der
+Sanden, James E Keenan, Jarkko Hietaniemi, Jerry D. Hedden, Karl Williamson,
+Leon Timmermans, Matthew Horsfall, Renee Baecker, Sawyer X, Shlomi Fish, Steve
+Hay, Tony Cook.
+
+The list above is almost certainly incomplete as it is automatically generated
+from version control history. In particular, it does not include the names of
+the (very much appreciated) contributors who reported issues to the Perl bug
+tracker.
+
+Many of the changes included in this version originated in the CPAN modules
+included in Perl's core. We're grateful to the entire CPAN community for
+helping Perl to flourish.

+=head1 Reporting Bugs
+
+If you find what you think is a bug, you might check the perl bug database
+at L<https://rt.perl.org/> . There may also be information at
+L<http://www.perl.org/> , the Perl Home Page.
+
+If you believe you have an unreported bug, please run the L<perlbug> program
+included with your release. Be sure to trim your bug down to a tiny but
+sufficient test case. Your bug report, along with the output of C<perl -V>,
+will be sent off to perlbug@perl.org to be analysed by the Perl porting team.
+
+If the bug you are reporting has security implications which make it
+inappropriate to send to a publicly archived mailing list, then see
+L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
+for details of how to report the issue.
+

+

+what changed.

-This release includes two important updates:
+XXX Any important notices here
-=over 4
+=head1 Core Enhancements
+
+XXX New core language features go here. Summarize user-visible core language
+enhancements. Particularly prominent performance optimisations could go
+here, but most should go in the L</Performance Enhancements> section.
+
+[ List each enhancement as a =head2 entry ]

+=head1 Security
+
+XXX Any security-related notices go here. In particular, any security
+vulnerabilities closed should be noted here rather than in the
+L</Selected Bug Fixes> section.
+
+[ List each security issue as a =head2 entry ]
+
+=head1 Incompatible Changes
+
+XXX For a release on a stable branch, this section aspires to be:
+
+ There are no changes intentionally incompatible with 5.XXX.XXX
+ If any exist, they are bugs, and we request that you submit a
+ report. See L</Reporting Bugs> below.
+
+[ List each incompatible change as a =head2 entry ]
+
+=head1 Deprecations
+
+XXX Any deprecated features, syntax, modules etc. should be listed here.
+
+=head2 Module removals
+
+XXX Remove this section if inapplicable.
+
+The following modules will be removed from the core distribution in a
+future release, and will at that time need to be installed from CPAN.
+Distributions on CPAN which require these modules will need to list them as
+prerequisites.
+
+The core versions of these modules will now issue C<"deprecated">-category
+warnings to alert you to this fact. To silence these deprecation warnings,
+install the modules in question from CPAN.
-=item * Turning on the removal of C<.> in C<@INC>
+Note that these are (with rare exceptions) fine modules that you are encouraged
+to continue to use. Their disinclusion from core primarily hinges on their
+necessity to bootstrapping a fully functional, CPAN-capable Perl installation,
+not usually on concerns over their design.
-=item * Providing a warning when C<do> is used on a file in C<.>
