=head1 NAME
-perldelta - what is new for perl v5.14.2
+perldelta - what is new for perl v5.16.2
=head1 DESCRIPTION
-This document describes differences between the 5.14.1 release and
-the 5.14.2 release.
+This document describes differences between the 5.16.1 release and
+the 5.16.2 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.
+If you are upgrading from an earlier release such as 5.16.0, first read
+L<perl5161delta>, which describes differences between 5.16.0 and
+5.16.1.
=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.
+There are no changes intentionally incompatible with 5.16.0
+If any exist, they are bugs, and we request that you submit a
+report. See L</Reporting Bugs> below.

-Backported bugfixes from CPAN version 1.9800. Ensures proper

-in the case where C<dynamic_config> is true. [rt.cpan.org #68835]

-
-The build system has been updated to work with the build tools under Mac OS X
-10.7.
+Configure now always adds -qlanglvl=extc99 to the CC flags on AIX when
+using xlC. This will make it easier to compile a number of XS-based modules
+that assume C99 [perl #113778].

-=item *
-
-In @INC filters (subroutines returned by subroutines in @INC), $_ used to
-misbehave: If returned from a subroutine, it would not be copied, but the
-variable itself would be returned; and freeing $_ (e.g., with C<undef *_>)
-would cause perl to crash. This has been fixed [perl #91880].
-
-=item *
-
-Perl 5.10.0 introduced some faulty logic that made "U*" in the middle of
-a pack template equivalent to "U0" if the input string was empty. This has
-been fixed [perl #90160].
-
-=item *
-
-C<caller> no longer leaks memory when called from the DB package if
-C<@DB::args> was assigned to after the first call to C<caller>. L<Carp>
-was triggering this bug [perl #97010].
-
-=item *
+=item * fix /\h/ equivalence with /[\h]/
-C<utf8::decode> had a nasty bug that would modify copy-on-write scalars'
-string buffers in place (i.e., skipping the copy). This could result in
-hashes having two elements with the same key [perl #91834].
-
-=item *
-
-Localising a tied variable used to make it read-only if it contained a
-copy-on-write string.
-
-=item *
-
-Elements of restricted hashes (see the L<fields> pragma) containing
-copy-on-write values couldn't be deleted, nor could such hashes be cleared
-(C<%hash = ()>).
-
-=item *
-
-Locking a hash element that is a glob copy no longer causes subsequent
-assignment to it to corrupt the glob.
-
-=item *
-
-A panic involving the combination of the regular expression modifiers
-C</aa> introduced in 5.14.0 and the C<\b> escape sequence has been
-fixed [perl #95964].

-
-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.
