+=head1 NAME
+
+perl5340delta - what is new for perl v5.34.0
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.32.0 release and the 5.34.0
+release.
+
+If you are upgrading from an earlier release such as 5.30.0, first read
+L<perl5320delta>, which describes differences between 5.30.0 and 5.32.0.
+
+=head1 Core Enhancements
+
+=head2 Experimental Try/Catch Syntax
+
+An initial experimental attempt at providing C<try>/C<catch> notation has
+been added.
+
+    use feature 'try';
+
+    try {
+        a_function();
+    }
+    catch ($e) {
+        warn "An error occurred: $e";
+    }
+
+For more information, see L<perlsyn/"Try Catch Exception Handling">.
+
+=head2 C<qr/{,n}/> is now accepted
+
+An empty lower bound is now accepted for regular expression quantifiers,
+like C<{,3}>.
+
+=head2 Blanks freely allowed within but adjacent to curly braces
+
+(in double-quotish contexts and regular expression patterns)
+
+This means you can write things like S<C<\x{ FFFC }>> if you like.  This
+applies to all such constructs, namely C<\b{}>, C<\g{}>, C<\k{}>,
+C<\N{}>, C<\o{}>, and C<\x{}>; as well as the regular expression
+quantifier C<{I<m>,I<n>}>.  C<\p{}> and C<\P{}> retain their
+already-existing, even looser, rules mandated by the Unicode standard
+(see L<perluniprops/Properties accessible through \p{} and \P{}>).
+
+This ability is in effect regardless of the presence of the C</x>
+regular expression pattern modifier.
+
+Additionally, the comma in a regular expression braced quantifier may
+have blanks (tabs or spaces) before and/or after the comma, like
+S<C<qr/a{ 5, 7 }/>>.
+
+=head2 New octal syntax C<0oI<ddddd>>
+
+It is now possible to specify octal literals with C<0o> prefixes,
+as in C<0o123_456>, parallel to the existing construct to specify
+hexadecimal literal C<0xI<ddddd>> and binary literal C<0bI<ddddd>>.
+Also, the builtin C<oct()> function now accepts this new syntax.
+
+See L<perldata/Scalar value constructors> and L<perlfunc/oct EXPR>.

+
+Windows now supports L<symlink()|perlfunc/symlink> and

+[L<GH #18005|https://github.com/Perl/perl5/issues/18005>].
+
+Unlike POSIX systems, creating a symbolic link on Windows requires

+
+=head1 Internal Changes
+
+=over 4
+
+=item *
+
+Corrected handling of double and long double parameters for perl's
+implementation of formatted output for C<-Dusequadmath> builds.
+
+This applies to C<PerlIO_printf()>, C<croak()>, C<warn()>, C<sv_catpvf()> and
+their variants.
+
+Previously in C<quadmath> builds, code like:
+
+  PerlIO_printf(PerlIO_stderr(), "%g", somedouble);
+
+or
+
+  PerlIO_printf(PerlIO_stderr(), "%Lg", somelongdouble);
+
+would erroneously throw an exception "panic: quadmath invalid format
+...", since the code added for quadmath builds assumed C<NV>s were the
+only floating point format passed into these functions.
+
+This code would also process the standard C long double specifier C<L>
+as if it expected an C<NV> (C<__float128> for quadmath builds),
+resulting in undefined behaviour.
+
+These functions now correctly accept doubles, long doubles and NVs.
+
+=item *
+
+Previously the right operand of bitwise shift operators (shift amount)
+was implicitly cast from IV to int, but it might lead wrong results
+if IV does not fit in int.
+
+And also, shifting INT_MIN bits used to yield the shiftee unchanged
+(treated as 0-bit shift instead of negative shift).
+
+=item *
+
+A set of C<cop_hints_exists_{pv,pvn,pvs,sv}> functions was added,
+to support checking for the existence of keys in the hints hash of a
+specific cop without needing to create a mortal copy of said value.
+
+=item *
+
+An aid has been added for using the C<DEBUG> macros when debugging XS or
+C code. The comments in F<perl.h> describe C<DEBUG_PRE_STMTS> and
+C<DEBUG_POST_STMTS>. which you can C<#define> to do things like save and
+restore C<errno>, in case the C<DEBUG> calls are interfering with that,
+or to display timestamps, or which thread it's coming from, or the
+location of the call, or whatever.  You can make a quick hack to help
+you track something down without having to edit individual C<DEBUG>
+calls.
+
+=item *
+
+Make C<REFCOUNTED_HE_EXISTS> available outside of core
+
+=item *
+
+All C<SvTRUE>-ish functions now evaluate their arguments exactly once.
+In 5.32, plain L<perlapi/C<SvTRUE>> was changed to do that; now the rest
+do as well.
+
+=item *
+
+Unicode is now a first class citizen when considering the pattern /A*B/ where
+A and B are arbitrary.  The pattern matching code tries to make a tight loop
+to match the span of A's.  The logic of this was now really updated with
+support for UTF-8.
+
+=item *
+
+The L<re> module has a new function C<optimization>, which can return a
+hashref of optimization data discovered about a compiled regexp.
+
+=item *
+
+The C<PERL_GLOBAL_STRUCT> compilation option has been removed, and
+with it the need or the C<dVAR> macro.  C<dVAR> remains defined as a
+no-op outside C<PERL_CORE> for backwards compatiblity with XS modules.
+
+=item *
+
+A new savestack type C<SAVEt_HINTS_HH> has been added, which neatens the
+previous behaviour of C<SAVEt_HINTS>.  On previous versions the types and
+values pushed to the save stack would depend on whether the hints included the
+C<HINT_LOCALIZE_HH> bit, which complicates external code that inspects the
+save stack. The new version uses a different savestack type to indicate the
+difference.
+
+=item *
+
+A new API function L<perlapi/av_count> has been added which gives a
+clearly named way to find how many elements are in an array.

+=head1 Selected Bug Fixes
+
+=over 4
+
+=item *
+
+Setting C<%ENV> now properly handles upgraded strings in the key. Previously
+Perl sent the SV's internal PV directly to the OS; now it will handle keys
+as it has handled values since 5.18: attempt to downgrade the string first;
+if that fails then warn and use the utf8 form.
+
+=item *
+
+Fix a memory leak in regcomp.c
+[L<GH #18604|https://github.com/Perl/perl5/issues/18604>]
+
+=item * pack/unpack format 'D' now works on all systems that could support it
+
+Previously if C<NV == long double>, now it is supported on all platforms that
+have long doubles. In particular that means it is now also supported on
+quadmath platforms.
+
+=item *
+
+Skip trying to constant fold an incomplete op tree
+[L<GH #18380|https://github.com/Perl/perl5/issues/18380>]
+
+Constant folding of chained comparison op trees could fail under certain
+conditions, causing perl to crash. As a quick fix, constant folding is
+now skipped for such op trees. This also addresses
+[L<GH #17917|https://github.com/Perl/perl5/issues/17917>].
+
+=item *
+
+C<%g> formatting broken on Ubuntu-18.04, C<NVSIZE == 8>
+[L<GH #18170|https://github.com/Perl/perl5/issues/18170>]
+
+Buggy libc implementations of the C<gcvt> and C<qgcvt> functions
+caused C<(s)printf> to incorrectly truncate C<%g> formatted numbers.
+A new Configure probe now checks for this, with the result that the libc
+C<sprintf> will be used in place of C<gcvt> and C<qgcvt>.
+
+Tests added as part of this fix also revealed related problems in
+some Windows builds. The makefiles for MINGW builds on Windows have
+thus been adjusted to use C<USE_MINGW_ANSI_STDIO> by default, ensuring
+that they also provide correct C<(s)printf> formatting of numbers.
+
+=item *
+
+F<op.c>: croak on C<my $_> when C<use utf8> is in effect
+[L<GH #18449|https://github.com/Perl/perl5/issues/18449>]
+
+The lexical topic feature experiment was removed in Perl v5.24 and
+declaring C<my $_> became a compile time error. However, it was previously
+still possible to make this declaration if C<use utf8> was in effect.
+

+F<regexec.c>: Fix assertion failure

+
+C<semctl()>, C<msgctl()>, and C<shmctl()> now attempt to downgrade the C<ARG>
+parameter if its value is being used as input to C<IPC_SET> or
+C<SETALL> calls.  A failed downgrade will thrown an exception.
+
+=item *
+
+In cases where C<semctl()>, C<msgctl()> or C<shmctl()> would treat the C<ARG>
+parameter as a pointer, an undefined value no longer generates a
+warning.  In most such calls the pointer isn't used anyway and this
+allows you to supply C<undef> for a value not used by the underlying
+function.
+
+=item *
+
+L<semop()|perlfunc/semop> now downgrades the C<OPSTRING> parameter,
+L<msgsnd()|perlfunc/msgsnd> now downgrades the C<MSG> parameter and
+L<shmwrite|perlfunc/shmwrite> now downgrades the C<STRING> parameter
+to treat them as bytes.  Previously they would be left upgraded,
+providing a corrupted structure to the underlying function call.
+
+=item *
+
+L<msgrcv()|perlfunc/msgrcv> now properly resets the UTF-8 flag the
+C<VAR> parameter when it is modified.  Previously the UTF-8 flag could
+be left on, resulting in a possibly corrupt result in C<VAR>.

+[ this is a template for a new perldelta file.  Any text flagged as XXX needs
+to be processed before release. ]
+
+perldelta - what is new for perl v5.35.0
 
 =head1 DESCRIPTION
 
-This document describes differences between the 5.32.0 release and the 5.34.0
+This document describes differences between the 5.34.0 release and the 5.35.0
 release.
 
-If you are upgrading from an earlier release such as 5.30.0, first read
-L<perl5320delta>, which describes differences between 5.30.0 and 5.32.0.
-
-=head1 Core Enhancements
-
-=head2 Experimental Try/Catch Syntax
-
-An initial experimental attempt at providing C<try>/C<catch> notation has
-been added.
-
-    use feature 'try';
-
-    try {
-        a_function();
-    }
-    catch ($e) {
-        warn "An error occurred: $e";
-    }
-
-For more information, see L<perlsyn/"Try Catch Exception Handling">.
-
-=head2 C<qr/{,n}/> is now accepted
-
-An empty lower bound is now accepted for regular expression quantifiers,
-like C<{,3}>.
-
-=head2 Blanks freely allowed within but adjacent to curly braces
-
-(in double-quotish contexts and regular expression patterns)
-
-This means you can write things like S<C<\x{ FFFC }>> if you like.  This
-applies to all such constructs, namely C<\b{}>, C<\g{}>, C<\k{}>,
-C<\N{}>, C<\o{}>, and C<\x{}>; as well as the regular expression
-quantifier C<{I<m>,I<n>}>.  C<\p{}> and C<\P{}> retain their
-already-existing, even looser, rules mandated by the Unicode standard
-(see L<perluniprops/Properties accessible through \p{} and \P{}>).
-
-This ability is in effect regardless of the presence of the C</x>
-regular expression pattern modifier.
-
-Additionally, the comma in a regular expression braced quantifier may
-have blanks (tabs or spaces) before and/or after the comma, like
-S<C<qr/a{ 5, 7 }/>>.
-
-=head2 New octal syntax C<0oI<ddddd>>
-
-It is now possible to specify octal literals with C<0o> prefixes,
-as in C<0o123_456>, parallel to the existing construct to specify
-hexadecimal literal C<0xI<ddddd>> and binary literal C<0bI<ddddd>>.
-Also, the builtin C<oct()> function now accepts this new syntax.
-
-See L<perldata/Scalar value constructors> and L<perlfunc/oct EXPR>.

 =head1 Internal Changes
 
-=over 4
-
-=item *
-
-Corrected handling of double and long double parameters for perl's
-implementation of formatted output for C<-Dusequadmath> builds.
-
-This applies to C<PerlIO_printf()>, C<croak()>, C<warn()>, C<sv_catpvf()> and
-their variants.
-
-Previously in C<quadmath> builds, code like:
-
-  PerlIO_printf(PerlIO_stderr(), "%g", somedouble);
-
-or
-
-  PerlIO_printf(PerlIO_stderr(), "%Lg", somelongdouble);
-
-would erroneously throw an exception "panic: quadmath invalid format
-...", since the code added for quadmath builds assumed C<NV>s were the
-only floating point format passed into these functions.
-
-This code would also process the standard C long double specifier C<L>
-as if it expected an C<NV> (C<__float128> for quadmath builds),
-resulting in undefined behaviour.
-
-These functions now correctly accept doubles, long doubles and NVs.
-
-=item *
-
-Previously the right operand of bitwise shift operators (shift amount)
-was implicitly cast from IV to int, but it might lead wrong results
-if IV does not fit in int.
-
-And also, shifting INT_MIN bits used to yield the shiftee unchanged
-(treated as 0-bit shift instead of negative shift).
-
-=item *
-
-A set of C<cop_hints_exists_{pv,pvn,pvs,sv}> functions was added,
-to support checking for the existence of keys in the hints hash of a
-specific cop without needing to create a mortal copy of said value.
-
-=item *
-
-An aid has been added for using the C<DEBUG> macros when debugging XS or
-C code. The comments in F<perl.h> describe C<DEBUG_PRE_STMTS> and
-C<DEBUG_POST_STMTS>. which you can C<#define> to do things like save and
-restore C<errno>, in case the C<DEBUG> calls are interfering with that,
-or to display timestamps, or which thread it's coming from, or the
-location of the call, or whatever.  You can make a quick hack to help
-you track something down without having to edit individual C<DEBUG>
-calls.

-=item *
-
-Unicode is now a first class citizen when considering the pattern /A*B/ where
-A and B are arbitrary.  The pattern matching code tries to make a tight loop
-to match the span of A's.  The logic of this was now really updated with
-support for UTF-8.

-The L<re> module has a new function C<optimization>, which can return a

-
-=item *
-
-A new savestack type C<SAVEt_HINTS_HH> has been added, which neatens the
-previous behaviour of C<SAVEt_HINTS>.  On previous versions the types and
-values pushed to the save stack would depend on whether the hints included the
-C<HINT_LOCALIZE_HH> bit, which complicates external code that inspects the
-save stack. The new version uses a different savestack type to indicate the
-difference.

-C<sprintf> will be used in place of C<gcvt> and C<qgcvt>.
