+=head1 NAME
+
+perl5144delta - what is new for perl v5.14.4
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.14.3 release and
+the 5.14.4 release.
+
+If you are upgrading from an earlier release such as 5.12.0, first read
+L<perl5140delta>, which describes differences between 5.12.0 and
+5.14.0.
+
+=head1 Core Enhancements
+
+No changes since 5.14.0.
+
+=head1 Security
+
+This release contains one major, and medium, and a number of minor
+security fixes.  The latter are included mainly to allow the test suite to
+pass cleanly with the clang compiler's address sanitizer facility.
+
+=head2 CVE-2013-1667: memory exhaustion with arbitrary hash keys
+
+With a carefully crafted set of hash keys (for example arguments on a
+URL), it is possible to cause a hash to consume a large amount of memory
+and CPU, and thus possibly to achieve a Denial-of-Service.
+
+This problem has been fixed.
+
+=head2 memory leak in Encode
+
+The UTF-8 encoding implementation in Encode.xs had a memory leak which has been
+fixed.
+
+=head2 [perl #111594] Socket::unpack_sockaddr_un heap-buffer-overflow
+
+A read buffer overflow could occur when copying C<sockaddr> buffers.
+Fairly harmless.
+
+This problem has been fixed.
+
+=head2 [perl #111586] SDBM_File: fix off-by-one access to global ".dir"
+
+An extra byte was being copied for some string literals. Fairly harmless.
+
+This problem has been fixed.
+
+=head2 off-by-two error in List::Util
+
+A string literal was being used that included two bytes beyond the
+end of the string. Fairly harmless.
+
+This problem has been fixed.
+
+=head2 [perl #115994] fix segv in regcomp.c:S_join_exact()
+
+Under debugging builds, while marking optimised-out regex nodes as type
+C<OPTIMIZED>, it could treat blocks of exact text as if they were nodes,
+and thus SEGV. Fairly harmless.
+
+This problem has been fixed.
+
+=head2 [perl #115992] PL_eval_start use-after-free
+
+The statement C<local $[;>, when preceded by an C<eval>, and when not part
+of an assignment, could crash. Fairly harmless.
+
+This problem has been fixed.
+
+=head2 wrap-around with IO on long strings
+
+Reading or writing strings greater than 2**31 bytes in size could segfault
+due to integer wraparound.
+
+This problem has been fixed.
+
+=head1 Incompatible Changes
+
+There are no changes intentionally incompatible with 5.14.0. If any
+exist, they are bugs and reports are welcome.
+
+=head1 Deprecations
+
+There have been no deprecations since 5.14.0.

+
+=item VMS
+
+5.14.3 failed to compile on VMS due to incomplete application of a patch
+series that allowed C<userelocatableinc> and C<usesitecustomize> to be
+used simultaneously.  Other platforms were not affected and the problem
+has now been corrected.

+
+=item *
+
+In Perl 5.14.0, C<$tainted ~~ @array> stopped working properly.  Sometimes
+it would erroneously fail (when C<$tainted> contained a string that occurs
+in the array I<after> the first element) or erroneously succeed (when
+C<undef> occurred after the first element) [perl #93590].

+
+=head1 Known Problems
+
+None.
+
+=head1 Acknowledgements
+
+Perl 5.14.4 represents approximately 5 months of development since Perl 5.14.3
+and contains approximately 1,700 lines of changes across 49 files from 12
+authors.
+
+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 5.14.4:
+
+Andy Dougherty, Chris 'BinGOs' Williams, Christian Hansen, Craig A. Berry,
+Dave Rolsky, David Mitchell, Dominic Hargreaves, Father Chrysostomos,
+Florian Ragwitz, Reini Urban, Ricardo Signes, 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.
+
+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 http://rt.perl.org/perlbug/ .  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 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 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 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.
