+=head1 NAME
+
+perl5142delta - what is new for perl v5.14.2
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.14.1 release and
+the 5.14.2 release.
+
+If you are upgrading from an earlier release such as 5.14.0, first read
+L<perl5141delta>, which describes differences between 5.14.0 and
+5.14.1.
+
+=head1 Core Enhancements

+No changes since 5.14.0.
+
+=head1 Security
+
+=head2 C<File::Glob::bsd_glob()> memory error with GLOB_ALTDIRFUNC (CVE-2011-2728).
+
+Calling C<File::Glob::bsd_glob> with the unsupported flag GLOB_ALTDIRFUNC would
+cause an access violation / segfault.  A Perl program that accepts a flags value from
+an external source could expose itself to denial of service or arbitrary code
+execution attacks.  There are no known exploits in the wild.  The problem has been
+corrected by explicitly disabling all unsupported flags and setting unused function
+pointers to null.  Bug reported by Clément Lecigne.
+
+=head2 C<Encode> decode_xs n-byte heap-overflow (CVE-2011-2939)
+
+A bug in C<Encode> could, on certain inputs, cause the heap to overflow.
+This problem has been corrected.  Bug reported by Robert Zacek.
+
+=head1 Incompatible Changes
+
+There are no changes intentionally incompatible with 5.14.0. If any
+exist, they are bugs and reports are welcome.

+
+There have been no deprecations since 5.14.0.

+
+C<PERL_GLOBAL_STRUCT> is broken.
+
+Since perl 5.14.0, building with C<-DPERL_GLOBAL_STRUCT> hasn't been
+possible. This means that perl currently doesn't work on any platforms that
+require it to be built this way, including Symbian.
+
+While C<PERL_GLOBAL_STRUCT> now works again on recent development versions of
+perl, it actually working on Symbian again hasn't been verified.
+
+We'd be very interested in hearing from anyone working with Perl on Symbian.

+
+=head1 Acknowledgements
+
+Perl 5.14.2 represents approximately three months of development since
+Perl 5.14.1 and contains approximately 1200 lines of changes
+across 61 files from 9 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 5.14.2:
+
+Craig A. Berry, David Golden, Father Chrysostomos, Florian Ragwitz, H.Merijn
+Brand, Karl Williamson, Nicholas Clark, Pau Amma and Ricardo Signes.
+
+=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.
