This document describes differences between the 5.32.0 release and the 5.34.0
release.
.PP
If you are upgrading from an earlier release such as 5.30.0, first read
perl5320delta, which describes differences between 5.30.0 and 5.32.0.

For more information, see \*(L"Try Catch Exception Handling\*(R" in perlsyn.
.ie n .SS """qr/{,n}/"" is now accepted"
.el .SS "\f(CWqr/{,n}/\fP is now accepted"
.IX Subsection "qr/{,n}/ is now accepted"
An empty lower bound is now accepted for regular expression quantifiers,
like \f(CW\*(C`{,3}\*(C'\fR.
.SS "Blanks freely allowed within but adjacent to curly braces"
.IX Subsection "Blanks freely allowed within but adjacent to curly braces"
(in double-quotish contexts and regular expression patterns)
.PP
This means you can write things like \f(CW\*(C`\ex{\ FFFC\ }\*(C'\fR if you like.  This
applies to all such constructs, namely \f(CW\*(C`\eb{}\*(C'\fR, \f(CW\*(C`\eg{}\*(C'\fR, \f(CW\*(C`\ek{}\*(C'\fR,
\&\f(CW\*(C`\eN{}\*(C'\fR, \f(CW\*(C`\eo{}\*(C'\fR, and \f(CW\*(C`\ex{}\*(C'\fR; as well as the regular expression
quantifier \f(CW\*(C`{\f(CIm\f(CW,\f(CIn\f(CW}\*(C'\fR.  \f(CW\*(C`\ep{}\*(C'\fR and \f(CW\*(C`\eP{}\*(C'\fR retain their
already-existing, even looser, rules mandated by the Unicode standard
(see \*(L"Properties accessible through \ep{} and \eP{}\*(R" in perluniprops).
.PP
This ability is in effect regardless of the presence of the \f(CW\*(C`/x\*(C'\fR
regular expression pattern modifier.
.PP
Additionally, the comma in a regular expression braced quantifier may
have blanks (tabs or spaces) before and/or after the comma, like
\&\f(CW\*(C`qr/a{\ 5,\ 7\ }/\*(C'\fR.

.el .SS "New octal syntax \f(CW0o\fP\f(CIddddd\fP\f(CW\fP"
.IX Subsection "New octal syntax 0oddddd"
It is now possible to specify octal literals with \f(CW\*(C`0o\*(C'\fR prefixes,
as in \f(CW\*(C`0o123_456\*(C'\fR, parallel to the existing construct to specify
hexadecimal literal \f(CW\*(C`0x\f(CIddddd\f(CW\*(C'\fR and binary literal \f(CW\*(C`0b\f(CIddddd\f(CW\*(C'\fR.
Also, the builtin \f(CW\*(C`oct()\*(C'\fR function now accepts this new syntax.

.Sp
or
.Sp
.Vb 1
\&  PerlIO_printf(PerlIO_stderr(), "%Lg", somelongdouble);

.Sp
would erroneously throw an exception \*(L"panic: quadmath invalid format

The \f(CW\*(C`PERL_GLOBAL_STRUCT\*(C'\fR compilation option has been removed, and
with it the need or the \f(CW\*(C`dVAR\*(C'\fR macro.  \f(CW\*(C`dVAR\*(C'\fR remains defined as a
no-op outside \f(CW\*(C`PERL_CORE\*(C'\fR for backwards compatiblity with \s-1XS\s0 modules.

A new savestack type \f(CW\*(C`SAVEt_HINTS_HH\*(C'\fR has been added, which neatens the
previous behaviour of \f(CW\*(C`SAVEt_HINTS\*(C'\fR.  On previous versions the types and
values pushed to the save stack would depend on whether the hints included the
\&\f(CW\*(C`HINT_LOCALIZE_HH\*(C'\fR bit, which complicates external code that inspects the
save stack. The new version uses a different savestack type to indicate the
difference.

Setting \f(CW%ENV\fR now properly handles upgraded strings in the key. Previously
Perl sent the \s-1SV\s0's internal \s-1PV\s0 directly to the \s-1OS\s0; 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.

Skip trying to constant fold an incomplete op tree
[\s-1GH\s0 #18380 <https://github.com/Perl/perl5/issues/18380>]
.Sp
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
[\s-1GH\s0 #17917 <https://github.com/Perl/perl5/issues/17917>].

.Sp
Buggy libc implementations of the \f(CW\*(C`gcvt\*(C'\fR and \f(CW\*(C`qgcvt\*(C'\fR functions
caused \f(CW\*(C`(s)printf\*(C'\fR to incorrectly truncate \f(CW%g\fR formatted numbers.
A new Configure probe now checks for this, with the result that the libc
\&\f(CW\*(C`sprintf\*(C'\fR will be used in place of \f(CW\*(C`gcvt\*(C'\fR and \f(CW\*(C`qgcvt\*(C'\fR.
.Sp
Tests added as part of this fix also revealed related problems in
some Windows builds. The makefiles for \s-1MINGW\s0 builds on Windows have
thus been adjusted to use \f(CW\*(C`USE_MINGW_ANSI_STDIO\*(C'\fR by default, ensuring
that they also provide correct \f(CW\*(C`(s)printf\*(C'\fR formatting of numbers.

[\s-1GH\s0 #18449 <https://github.com/Perl/perl5/issues/18449>]
.Sp
The lexical topic feature experiment was removed in Perl v5.24 and
declaring \f(CW\*(C`my $_\*(C'\fR became a compile time error. However, it was previously
still possible to make this declaration if \f(CW\*(C`use utf8\*(C'\fR was in effect.

\&\f(CW\*(C`semctl()\*(C'\fR, \f(CW\*(C`msgctl()\*(C'\fR, and \f(CW\*(C`shmctl()\*(C'\fR now attempt to downgrade the \f(CW\*(C`ARG\*(C'\fR
parameter if its value is being used as input to \f(CW\*(C`IPC_SET\*(C'\fR or
\&\f(CW\*(C`SETALL\*(C'\fR calls.  A failed downgrade will thrown an exception.
.IP "\(bu" 4
In cases where \f(CW\*(C`semctl()\*(C'\fR, \f(CW\*(C`msgctl()\*(C'\fR or \f(CW\*(C`shmctl()\*(C'\fR would treat the \f(CW\*(C`ARG\*(C'\fR
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 \f(CW\*(C`undef\*(C'\fR for a value not used by the underlying
function.

\&\fBsemop()\fR now downgrades the \f(CW\*(C`OPSTRING\*(C'\fR parameter,
\&\fBmsgsnd()\fR now downgrades the \f(CW\*(C`MSG\*(C'\fR parameter and
shmwrite now downgrades the \f(CW\*(C`STRING\*(C'\fR parameter
to treat them as bytes.  Previously they would be left upgraded,
providing a corrupted structure to the underlying function call.

\&\fBmsgrcv()\fR now properly resets the \s-1UTF\-8\s0 flag the
\&\f(CW\*(C`VAR\*(C'\fR parameter when it is modified.  Previously the \s-1UTF\-8\s0 flag could
be left on, resulting in a possibly corrupt result in \f(CW\*(C`VAR\*(C'\fR.
