+=head1 NAME
+
+perl5242delta - what is new for perl v5.24.2
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.24.1 release and the 5.24.2
+release.
+
+If you are upgrading from an earlier release such as 5.24.0, first read
+L<perl5241delta>, which describes differences between 5.24.0 and 5.24.1.

+=head1 Security
+
+=head2 Improved handling of '.' in @INC in base.pm
+
+The handling of (the removal of) C<'.'> in C<@INC> in L<base> has been
+improved.  This resolves some problematic behaviour in the approach taken in
+Perl 5.24.1, which is probably best described in the following two threads on
+the Perl 5 Porters mailing list:
+L<http://www.nntp.perl.org/group/perl.perl5.porters/2016/08/msg238991.html>,
+L<http://www.nntp.perl.org/group/perl.perl5.porters/2016/10/msg240297.html>.
+
+=head2 "Escaped" colons and relative paths in PATH
+
+On Unix systems, Perl treats any relative paths in the PATH environment
+variable as tainted when starting a new process.  Previously, it was allowing a
+backslash to escape a colon (unlike the OS), consequently allowing relative
+paths to be considered safe if the PATH was set to something like C</\:.>.  The
+check has been fixed to treat C<.> as tainted in that example.

+=head1 Acknowledgements
+
+Perl 5.24.2 represents approximately 6 months of development since Perl 5.24.1
+and contains approximately 2,500 lines of changes across 53 files from 18
+authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 960 lines of changes to 17 .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 5.24.2:
+
+Aaron Crane, Abigail, Aristotle Pagaltzis, Chris 'BinGOs' Williams, Dan
+Collins, David Mitchell, Eric Herman, Father Chrysostomos, James E Keenan, Karl
+Williamson, Lukas Mai, Renee Baecker, Ricardo Signes, Sawyer X, Stevan Little,
+Steve Hay, Tony Cook, Yves Orton.
+
+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 articles recently
+posted to the comp.lang.perl.misc newsgroup and 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.
