+=head1 NAME
+
+perl5416delta - what is new for perl v5.41.6
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.41.5 release and the 5.41.6
+release.
+
+If you are upgrading from an earlier release such as 5.41.4, first read
+L<perl5415delta>, which describes differences between 5.41.4 and 5.41.5.

+=item *
+
+Code that uses the C<indexed> function from the L<builtin> module to generate
+a list of index/value pairs out of array which is then passed into a
+two-variable C<foreach> list to unpack those again is now optimised to be more
+efficient.
+
+    my @array = (...);
+
+    foreach my ($idx, $val) (builtin::indexed @array) {
+        ...
+    }
+
+In particular, a temporary list twice the size of the original
+array is no longer generated.  Instead, the list iterates down the array
+in-place directly, in the same way that C<foreach (@array)> would do.

+(instead of having the module create a pipe internally). Previously, only

+The perl parser would erroneously parse like C<=cut> some other POD directives

+The following cases were affected: I<cut> followed by a digit (e.g.
+C<=cut2studio>), I<cut> followed by an underscore (e.g. C<=cut_grass>), and in
+string C<eval>, any identifier starting with I<cut> (e.g. C<=cute>).

+=head1 Known Problems
+
+=over 4
+
+=item *
+
+C<cygwin> builds may fail during testing due to a conflict between the
+load addresses of F<cygperl5_41_6.dll> and
+F<olib/auto/I18N/Langinfo/Langinfo.dll>.  This will also be visible
+for anything that attempts to fork() with C<I18N::LangInfo> loaded.
+
+This is known to fail for builds with options that increase the size
+of the binary, such as C<-DDEBUGGING>, C<-Doptimize="-O0 -g"> or
+C<-Doptimize="-O2 -g -march=x86-64-v2">.
+
+This can be avoided by building perl with
+C<-Astatic_ext=I18N/Langinfo>.
+
+The base addresses are generated by the linker based on the names of
+the DLLs, so this is expected to clear up for 5.41.7.

+=head1 Acknowledgements
+
+Perl 5.41.6 represents approximately 4 weeks of development since Perl
+5.41.5 and contains approximately 8,400 lines of changes across 180 files
+from 14 authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 6,700 lines of changes to 120 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its fourth decade thanks to a vibrant
+community of users and developers. The following people are known to have
+contributed the improvements that became Perl 5.41.6:
+
+Chad Granum, Chris 'BinGOs' Williams, Daniel Dragan, David Mitchell, Graham
+Knop, James E Keenan, Karl Williamson, Lukas Mai, Marin Tsanov, Paul Evans,
+pyrrhlin, Richard Leach, Thibault Duponchelle, 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.
+
+For a more complete list of all of Perl's historical contributors, please
+see the F<AUTHORS> file in the Perl source distribution.
+
+=head1 Reporting Bugs
+
+If you find what you think is a bug, you might check the perl bug database
+at L<https://github.com/Perl/perl5/issues>. There may also be information at
+L<https://www.perl.org/>, the Perl Home Page.
+
+If you believe you have an unreported bug, please open an issue at
+L<https://github.com/Perl/perl5/issues>. Be sure to trim your bug down to a
+tiny but sufficient test case.
+
+If the bug you are reporting has security implications which make it
+inappropriate to send to a public issue tracker, then see
+L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
+for details of how to report the issue.
+
+=head1 Give Thanks
+
+If you wish to thank the Perl 5 Porters for the work we had done in Perl 5,
+you can do so by running the C<perlthanks> program:
+
+    perlthanks
+
+This will send an email to the Perl 5 Porters list with your show of thanks.
