       perl5224delta - what is new for perl v5.22.4

       This document describes differences between the 5.22.3 release and the
       5.22.4 release.

       If you are upgrading from an earlier release such as 5.22.2, first read
       perl5223delta, which describes differences between 5.22.2 and 5.22.3.

   Improved handling of '.' in @INC in base.pm
       The handling of (the removal of) '.' in @INC in base has been improved.
       This resolves some problematic behaviour in the approach taken in Perl
       5.22.3, which is probably best described in the following two threads
       on the Perl 5 Porters mailing list:

   "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 "/\:.".  The check has been fixed to treat "." as
       tainted in that example.

Modules and Pragmata
   Updated Modules and Pragmata
       o   base has been upgraded from version 2.22 to 2.22_01.

       o   Module::CoreList has been upgraded from version 5.20170114_22 to

Selected Bug Fixes
       o   Fixed a crash with "s///l" where it thought it was dealing with
           UTF-8 when it wasn't.  [perl #129038]

       Perl 5.22.4 represents approximately 6 months of development since Perl
       5.22.3 and contains approximately 2,200 lines of changes across 52
       files from 16 authors.

       Excluding auto-generated files, documentation and release tools, there
       were approximately 970 lines of changes to 18 .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 5.22.4:

       Aaron Crane, Abigail, Aristotle Pagaltzis, Chris 'BinGOs' Williams,
       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.

       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 AUTHORS file in the Perl source distribution.

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 https://rt.perl.org/ .  There may also be information at
       http://www.perl.org/ , the Perl Home Page.

       If you believe you have an unreported bug, please run the 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 "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 please
       send it to perl5-security-report@perl.org.  This points to a closed
       subscription unarchived mailing list, which includes all the core
       committers, who will be able to help assess the impact of issues,
       figure out a resolution, and help co-ordinate the release of patches to
       mitigate or fix the problem across all platforms on which Perl is
       supported.  Please only use this address for security issues in the
       Perl core, not for modules independently distributed on CPAN.
