+
+perl5433delta - what is new for perl v5.43.3
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.43.2 release and the 5.43.3
+release.
+
+If you are upgrading from an earlier release such as 5.43.1, first read
+L<perl5432delta>, which describes differences between 5.43.1 and 5.43.2.

+L<B> has been upgraded from version 1.89 to 1.90.
+
+=item *
+
+L<B::Concise> has been upgraded from version 1.007 to 1.009. It now correctly
+omits all its internal BEGIN blocks when asked to report BEGIN blocks in a
+caller's code. Previously it only omitted some of them.
+
+=item *
+
+L<B::Deparse> has been upgraded from version 1.86 to 1.87.
+
+=item *
+
+L<ExtUtils::ParseXS> has been upgraded from version 3.59 to 3.60. This
+release changes the ordering of the processing of typemap files which have
+been specified via C<xsubpp -typemap> arguments so that (as was the case
+prior to Perl 5.10.0) these files are applied last rather than first, and
+thus take priority over any system typemap files.
+
+=item *
+
+L<ExtUtils::Typemaps> has been upgraded from version 3.59 to 3.60.

+=item *
+
+L<Time::HiRes> has been upgraded from version 1.9778 to 1.9779.
+
+The subsecond-resolution C<sleep> function provided by L<Time::HiRes> now has
+the same prototype as perl's built-in L<sleep function|perlfunc/sleep>. This
+means it now requires a scalar argument, not a list, just like C<CORE::sleep>:
+
+    use Time::HiRes qw(sleep);
+
+    sleep(1, "foo", "bar");  # Syntax error.
+    # It used to silently ignore the extra arguments.
+
+    my @t = 42;
+    sleep @t;
+    # Evaluates @t in scalar context (giving the number of elements)
+    # and sleeps for one second. It used to sleep for 42 seconds.

+
+=over 4
+
+=item *
+
+Certain diagnostics about byte sequences that are supposed to comprise a
+UTF-8 encoded character, but that are invalid in some way, now don't
+include bytes irrelevant to that determination.  An example is
+
+=over
+
+=item old message
+
+Malformed UTF-8 character: C<\xc1\x27> (any UTF-8 sequence that starts with
+C<\xc1> is overlong which can and should be represented with a different,
+shorter sequence)
+
+=item new message
+
+Malformed UTF-8 character: C<\xc1> (any UTF-8 sequence that starts with
+C<\xc1> is overlong which can and should be represented with a different,
+shorter sequence)
+
+=back
+
+In this case the C<\xc1> is all that is needed to make the sequence
+invalid.  Whatever comes after it is irrelevant (in this case, C<\x27>),
+and including it in the message might lead the reader to think that it
+somehow does matter.

+
+=head1 Internal Changes
+
+=over 4
+
+=item *
+
+A new function C<valid_utf8_to_uv> has been added.  This is synonymous
+with C<valid_utf8_to_uvchr>; its reason for existence is to have
+consistent spelling with the names of the other functions that translate
+from UTF-8, so you don't have to remember a different spelling.
+
+=item *
+
+L<perlapi/C<newSVsv_flags_NN>> is a new function for creating a new SV
+and assigning the value(s) of an existing SV to it.
+
+Historically, C<Perl_newSVsv_flags> and C<Perl_sv_mortalcopy_flags> would
+pass a new SV head and the original SV to C<Perl_sv_setsv_flags>. However,
+the latter contains many branches of no relevance to a fresh SV, so they
+now make use of the new function to streamline the process.
+
+C<Perl_newSVsv_flags> is now essentially a NULL pointer check and wrapper
+around the new function, so has been moved into F<sv_inline.h>.
+
+=item *
+
+L<perlapi/C<STATIC_ASSERT_DECL>> and C<STATIC_ASSERT_STMT> are like
+C<assert()>, but are evaluated at compile time.  That means their
+argument must be a constant expression that can be verified by the
+compiler, and so they effectively have no cost, not appearing in the
+code that gets executed.  These were added in v5.28, but not until now
+have we opened their use up to XS writers.  At the same time, a new
+variant has been added, C<STATIC_ASSERT_EXPR> which is suitable for use
+in an expression, such as a comma expression in a C macro.

+=head1 Selected Bug Fixes
+
+=over 4
+
+=item * INTERFACE keyword in XS
+
+Fixed a couple of issues with the INTERFACE keyword in XS.
+
+[L<GH #23640|https://github.com/Perl/perl5/issues/23640>]
+
+=item * C<&CORE::__CLASS__> no longer returns invalid results
+
+C<CORE::__CLASS__> would work as expected when used as a bareword or aliased:
+
+    use feature qw(class);
+    class Foo {
+        BEGIN { *cls = \&CORE::__CLASS__; }
+        method bar() {
+            my $class1 = CORE::__CLASS__;  # ok
+            my $class2 = cls;              # ok
+        }
+    }
+
+But when called with an ampersand (C<&CORE::__CLASS__()>) or through a
+reference (C<< my $ref = \&CORE::__CLASS__; $ref->() >>), it would return
+unrelated strings. These runtime calls have been fixed to throw an error of the
+form C<&CORE::__CLASS__ cannot be called directly> instead of silently
+returning incorrect results.
+
+[L<GH #23737|https://github.com/Perl/perl5/issues/23737>]
+
+=item * C<parse_subsignature()> can now handle empty subroutine signatures
+
+Previously, calling the C<parse_subsignature()> API function with an empty
+signature would cause a "Syntax error" failure, requiring code which calls it
+to detect the special case and take appropriate steps.  This is now fixed,
+returning the same optree that the parser would yield for a regular empty
+signature during normal parse time.

+=head1 Acknowledgements
+
+Perl 5.43.3 represents approximately 5 weeks of development since Perl
+5.43.2 and contains approximately 150,000 lines of changes across 330 files
+from 26 authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 26,000 lines of changes to 180 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its fourth decade thanks to a vibrant
+community of users and developers. The following people are known to have
+contributed the improvements that became Perl 5.43.3:
+
+Branislav Zahradník, brian d foy, Chad Granum, Craig A. Berry, Daniel
+Dragan, David Mitchell, Igor Todorovski, James E Keenan, James Raspass, Jörg

+Samuel Young, TAKAI Kousuke, Thibault Duponchelle, Tomasz Konojacki, Tom
+Wyant, Tony Cook, Unicode Consortium.
+
+The list above is almost certainly incomplete as it is automatically
+generated from version control history. In particular, it does not include
+the names of the (very much appreciated) contributors who reported issues to
+the Perl bug tracker.
+
+Many of the changes included in this version originated in the CPAN modules
+included in Perl's core. We're grateful to the entire CPAN community for
+helping Perl to flourish.
