+release.
+
+If you are upgrading from an earlier release such as 5.39.0, first read
+L<perl5400delta>, which describes differences between 5.39.0 and 5.40.0.
+
+=head1 Incompatible Changes
+
+There are no changes intentionally incompatible with 5.40.0.  If any exist,
+they are bugs, and we request that you submit a report.  See L</Reporting Bugs>
+below.

+=head2 Changes to Existing Documentation

+=head1 Selected Bug Fixes
+
+=over 4
+
+=item *
+
+Starting in Perl 5.39.8, L<POSIX/C<strftime>> would crash or produce odd errors
+(such as C<Out of memory in perl:util:safesysmalloc>) when given a format
+string that wasn't actually a string, but a number, C<undef>, or an object
+(even one with overloaded string conversion).
+
+Now C<strftime> stringifies its first argument, as before.
+[L<GH #22498|https://github.com/Perl/perl5/issues/22498>]
+
+=item *
+
+Builds with C<-msse> and quadmath on 32-bit x86 systems would crash with a
+misaligned access early in the build.
+[L<GH #22577|https://github.com/Perl/perl5/issues/22577>]
+
+=item *
+
+Using C<goto> to tail call, or using the call_sv() and related APIs to call,
+any of trim(), refaddr(), reftype(), ceil(), floor() or stringify() in the
+C<builtin::> package would crash or assert due to a C<TARG> handling bug.
+[L<GH #22542|https://github.com/Perl/perl5/issues/22542>]
+
+=item *
+
+Fixed an issue where C<utf8n_to_uvchr()> failed to correctly identify certain
+invalid UTF-8 sequences as invalid.  Specifically, sequences that start with
+continuation bytes or unassigned bytes could cause unexpected behaviour or a
+panic.  This fix ensures that such invalid sequences are now properly detected
+and handled.  This correction also resolves related issues in modules that
+handle UTF-8 processing, such as L<Encode>.
+
+=item *
+
+Fixed a double free error or possible memory leak when failing to compile
+certain regexps.  [L<GH #21661|https://github.com/Perl/perl5/issues/21661>]

+=head1 Acknowledgements
+
+Perl 5.40.1 represents approximately 7 months of development since Perl 5.40.0
+and contains approximately 5,600 lines of changes across 54 files from 15
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 1,800 lines of changes to 19 .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 5.40.1:
+
+Andrei Horodniceanu, Chris 'BinGOs' Williams, E. Choroba, Graham Knop, James E
+Keenan, Karen Etheridge, Karl Williamson, Lukas Mai, Masahiro Honma, Max
+Maischein, Philippe Bruhat (BooK), Richard Leach, Steve Hay, 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.
