+
+perl5295delta - what is new for perl v5.29.5
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.29.4 release and the 5.29.5
+release.
+
+If you are upgrading from an earlier release such as 5.29.3, first read
+L<perl5294delta>, which describes differences between 5.29.3 and 5.29.4.
+
+=head1 Core Enhancements
+
+=head2 C<-Drv> now means something on C<-DDEBUGGING> builds
+
+Now, adding the verbose flag (C<-Dv>) to the C<-Dr> flag turns on all
+possible regular expression debugging.
+
+=head1 Performance Enhancements
+
+=over 4
+
+=item *
+
+Regular expression pattern matching of things like C<qr/[^I<a>]/> is
+significantly sped up, where I<a> is any ASCII character.  Which classes
+will get this speed up is complicated and depends on the underlying bit
+patterns of those characters, so differs between ASCII and EBCDIC
+platforms, but all case pairs, like C<qr/[Gg]/> are included, as is
+C<[^01]>.

+=item Mac OS X
+
+Perl's build and testing process on Mac OS X for C<-Duseshrplib>
+builds is now compatible with Mac OS X System Integrity Protection
+(SIP).
+
+SIP prevents binaries in F</bin> (and a few other places) being passed
+the C<DYLD_LIBRARY_PATH> environment variable.  For our purposes this
+prevents C<DYLD_LIBRARY_PATH> from being passed to the shell, which
+prevents that variable being passed to the testing or build process,
+so running C<perl> couldn't find F<libperl.dylib>.
+
+To workaround that, the initial build of the F<perl> executable
+expects to find F<libperl.dylib> in the build directory, and the
+library path is then adjusted during installation to point to the
+installed library.

+=head1 Acknowledgements
+
+Perl 5.29.5 represents approximately 4 weeks of development since Perl
+5.29.4 and contains approximately 4,000 lines of changes across 110 files
+from 18 authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 2,600 lines of changes to 51 .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 5.29.5:
+
+Aaron Crane, Chris 'BinGOs' Williams, Dagfinn Ilmari Mannsåker, Dan
+Dedrick, David Cantrell, David Mitchell, Dominic Hargreaves, H.Merijn Brand,
+James Clarke, James E Keenan, Karen Etheridge, Karl Williamson, Niko Tyni,
+Pali, Phil Pearl (Lobbes), Sawyer X, Tomasz Konojacki, 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://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.
+
+=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.

+
+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.
+
+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.
