+=head1 NAME
+
+perl5135delta - what is new for perl v5.13.5
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.13.4 release and
+the 5.13.5 release.
+
+If you are upgrading from an earlier release such as 5.13.3, first read
+L<perl5134delta>, which describes differences between 5.13.3 and
+5.13.4.
+
+=head1 Core Enhancements
+
+=head2 Adjacent pairs of nextstate opcodes are now optimized away
+
+Previously, in code such as
+
+    use constant DEBUG => 0;
+
+    sub GAK {
+        warn if DEBUG;
+        print "stuff\n";
+    }
+
+the ops for C<warn if DEBUG;> would be folded to a C<null> op (C<ex-const>), but
+the C<nextstate> op would remain, resulting in a runtime op dispatch of
+C<nextstate>, C<nextstate>, ...
+
+The execution of a sequence of C<nextstate> ops is indistinguishable from just
+the last C<nextstate> op so the peephole optimizer now eliminates the first of
+a pair of C<nextstate> ops, except where the first carries a label, since labels
+must not be eliminated by the optimizer and label usage isn't conclusively known
+at compile time.
+
+=head2 API function to parse statements
+
+The C<parse_fullstmt> function has been added to allow parsing of a single
+complete Perl statement.  See L<perlapi> for details.
+
+=head2 API functions for accessing the runtime hinthash
+
+A new C API for introspecting the hinthash C<%^H> at runtime has been added.
+See C<cop_hints_2hv>, C<cop_hints_fetchpvn>, C<cop_hints_fetchpvs>,
+C<cop_hints_fetchsv>, and C<hv_copy_hints_hv> in L<perlapi> for details.
+
+=head2 C interface to C<caller()>
+
+The C<caller_cx> function has been added as an XSUB-writer's equivalent of
+C<caller()>.  See L<perlapi> for details.
+
+=head1 Incompatible Changes
+
+=head2 Magic variables outside the main package
+
+In previous versions of Perl, magic variables like C<$!>, C<%SIG>, etc. would
+'leak' into other packages.  So C<%foo::SIG> could be used to access signals,
+C<${"foo::!"}> (with strict mode off) to access C's C<errno>, etc.
+
+This was a bug, or an 'unintentional' feature, which caused various ill effects,
+such as signal handlers being wiped when modules were loaded, etc.
+
+This has been fixed (or the feature has been removed, depending on how you see
+it).
+
+=head2 Smart-matching against array slices
+
+Previously, the following code resulted in a successful match:
+
+    my @a = qw(a y0 z);
+    my @b = qw(a x0 z);
+    $a[0 .. $#b] ~~ @b;
+
+This odd behaviour has now been fixed
+L<[perl #77468]|http://rt.perl.org/rt3//Public/Bug/Display.html?id=77468>.
+
+=head2 C API changes
+
+The first argument of the C API function C<Perl_fetch_cop_label> has changed
+from C<struct refcounted he *> to C<COP *>, to better insulate the user from
+implementation details.
+
+This API function was marked as "may change", and likely isn't in use outside
+the core.  (Neither an unpacked CPAN, nor Google's codesearch, finds any other
+references to it.)
+
+=head1 Deprecations
+
+=head2 Use of qw(...) as parentheses
+
+Historically the parser fooled itself into thinking that C<qw(...)> literals
+were always enclosed in parentheses, and as a result you could sometimes omit
+parentheses around them:
+
+    for $x qw(a b c) { ... }
+
+The parser no longer lies to itself in this way.  Wrap the list literal in
+parentheses, like:
+
+    for $x (qw(a b c)) { ... }
+
+=head1 Performance Enhancements
+
+=over 4
+
+=item *
+
+Scalars containing regular expressions now only allocate the part of the C<SV>
+body they actually use, saving some space.
+
+=item *
+
+Compiling regular expressions has been made faster for the case where upgrading
+the regex to utf8 is necessary but that isn't known when the compilation begins.

+
+When C<perlio> became the default and C<unixio> became the default bottom layer,

+which has always explicitly used C<0666> as the permission mask.
+
+To avoid this, C<0777> is now passed as the permissions to C<open()>.  In the
+VMS CRTL, C<0777> has a special meaning over and above intersecting with the
+current umask; specifically, it allows Unix syscalls to preserve native default
+permissions.

+
+C<CALL_FPTR> and C<CPERLscope> have been deprecated.
+
+Those are left from an old implementation of C<MULTIPLICITY> using C++ objects,
+which was removed in Perl 5.8.  Nowadays these macros do exactly nothing, so
+they shouldn't be used anymore.
+
+For compatibility, they are still defined for external C<XS> code.  Only
+extensions defining C<PERL_CORE> must be updated now.

+C<lex_stuff_pvs()> has been added as a convenience macro wrapping
+C<lex_stuff_pvn()> for literal strings.

+
+Several memory leaks in cloning and freeing threaded Perl interpreters have been

+
+A possible string corruption when doing regular expression matches on overloaded

+See L</Magic variables outside the main package> above
+L<[perl #76138]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=76138>.
+
+=item *
+
+Opening a glob reference via C<< open $fh, "E<gt>", \*glob >> will no longer
+cause the glob to be corrupted when the filehandle is printed to.  This would
+cause perl to crash whenever the glob's contents were accessed
+L<[perl #77492]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=77492>.
+
+=item *
+
+The postincrement and postdecrement operators, C<++> and C<-->, used to cause
+leaks when being used on references.  This has now been fixed.
+
+=item *
+
+A bug when replacing the glob of a loop variable within the loop has been fixed
+L<[perl #21469]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=21469>.  This
+means the following code will no longer crash:
+
+    for $x (...) {
+        *x = *y;
+    }
+
+=item *
+
+Perl would segfault if the undocumented C<Internals> functions that used
+reference prototypes were called with the C<&foo()> syntax, e.g.
+C<&Internals::SvREADONLY(undef)>
+L<[perl #77776]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=77776>.
+
+These functions now call C<SvROK> on their arguments before dereferencing them
+with C<SvRV>, and we test for this case in F<t/lib/universal.t>.
+
+=item *
+
+When assigning a list with duplicated keys to a hash, the assignment used to
+return garbage and/or freed values:
+
+    @a = %h = (list with some duplicate keys);
+
+This has now been fixed
+L<[perl #31865]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=31865>.
+
+=item *
+
+An earlier release of the 5.13 series of Perl changed the semantics of opening a
+reference to a copy of a glob:
+
+    my $var = *STDOUT;
+    open my $fh, '>', \$var;
+
+This was a mistake, and the previous behaviour from Perl 5.10 and 5.12, which is
+to treat \$var as a scalar reference, has now been restored.

+
+The regular expression bracketed character class C<[\8\9]> was effectively the
+same as C<[89\000]>, incorrectly matching a NULL character.  It also gave
+incorrect warnings that the C<8> and C<9> were ignored.  Now C<[\8\9]> is the
+same as C<[89]> and gives legitimate warnings that C<\8> and C<\9> are
+unrecognized escape sequences, passed-through.

+=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 B<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.

 =head1 Incompatible Changes
 
-=head2 Magic variables outside the main package
-
-In previous versions of Perl, magic variables like C<$!>, C<%SIG>, etc. would
-'leak' into other packages.  So C<%foo::SIG> could be used to access signals,
-C<${"foo::!"}> (with strict mode off) to access C's C<errno>, etc.
-
-This was a bug, or an 'unintentional' feature, which caused various ill effects,
-such as signal handlers being wiped when modules were loaded, etc.
+XXX For a release on a stable branch, this section aspires to be:
 
-This has been fixed (or the feature has been removed, depending on how you see
-it).
+    There are no changes intentionally incompatible with 5.XXX.XXX. If any
+    exist, they are bugs and reports are welcome.
 
-=head2 Smart-matching against array slices
-
-Previously, the following code resulted in a successful match:
-
-    my @a = qw(a y0 z);
-    my @b = qw(a x0 z);
-    $a[0 .. $#b] ~~ @b;
-
-This odd behaviour has now been fixed
-L<[perl #77468]|http://rt.perl.org/rt3//Public/Bug/Display.html?id=77468>.
-
-=head2 C API changes
-
-The first argument of the C API function C<Perl_fetch_cop_label> has changed
-from C<struct refcounted he *> to C<COP *>, to better insulate the user from
-implementation details.
-
-This API function was marked as "may change", and likely isn't in use outside
-the core.  (Neither an unpacked CPAN, nor Google's codesearch, finds any other
-references to it.)
+[ List each incompatible change as a =head2 entry ]
 
 =head1 Deprecations
 
-=head2 Use of qw(...) as parentheses
-
-Historically the parser fooled itself into thinking that C<qw(...)> literals
-were always enclosed in parentheses, and as a result you could sometimes omit
-parentheses around them:
-
-    for $x qw(a b c) { ... }
+XXX Any deprecated features, syntax, modules etc. should be listed here.
+In particular, deprecated modules should be listed here even if they are
+listed as an updated module in the L</Modules and Pragmata> section.
 
-The parser no longer lies to itself in this way.  Wrap the list literal in
