=head1 NAME
-[ 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 v5.39.3
+perldelta - what is new for perl v5.39.7
=head1 DESCRIPTION
-This document describes differences between the 5.39.2 release and the 5.39.3
+This document describes differences between the 5.39.6 release and the 5.39.7
release.
-If you are upgrading from an earlier release such as 5.39.1, first read
-L<perl5392delta>, which describes differences between 5.39.1 and 5.39.2.

-=head1 Notice
-
-XXX Any important notices here
-
-=head1 Core Enhancements
-
-XXX New core language features go here. Summarize user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
-
-[ List each enhancement as a =head2 entry ]
-
-=head1 Security
-
-XXX Any security-related notices go here. In particular, any security
-vulnerabilities closed should be noted here rather than in the
-L</Selected Bug Fixes> section.
-
-[ List each security issue as a =head2 entry ]
-
-=head1 Incompatible Changes
-
-XXX For a release on a stable branch, this section aspires to be:
-
- There are no changes intentionally incompatible with 5.XXX.XXX
- If any exist, they are bugs, and we request that you submit a
- report. See L</Reporting Bugs> below.
-
-[ List each incompatible change as a =head2 entry ]
-
-=head1 Deprecations
-
-XXX Any deprecated features, syntax, modules etc. should be listed here.
-
-=head2 Module removals
-
-XXX Remove this section if not applicable.
-
-The following modules will be removed from the core distribution in a
-future release, and will at that time need to be installed from CPAN.
-Distributions on CPAN which require these modules will need to list them as
-prerequisites.
-
-The core versions of these modules will now issue C<"deprecated">-category
-warnings to alert you to this fact. To silence these deprecation warnings,
-install the modules in question from CPAN.
-
-Note that these are (with rare exceptions) fine modules that you are encouraged
-to continue to use. Their disinclusion from core primarily hinges on their
-necessity to bootstrapping a fully functional, CPAN-capable Perl installation,
-not usually on concerns over their design.

+If you are upgrading from an earlier release such as 5.39.5, first read
+L<perl5396delta>, which describes differences between 5.39.5 and 5.39.6.
=head1 Modules and Pragmata
-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here. If Module::CoreList is updated, generate an initial draft of the
-following sections using F<Porting/corelist-perldelta.pl>. A paragraph summary
-for important changes should then be added by hand. In an ideal world,
-dual-life modules would have a F<Changes> file that could be cribbed.
-
The list of new and updated modules is modified automatically as part of
preparing a Perl release, so the only reason to manually add entries here is if
you're summarising the important changes in the module update. (Also, if the
manually-added details don't match the automatically-generated ones, the
release manager will have to investigate the situation carefully.)

=over 4
=item *
-A new API function has been added that simplifies C (or XS) code that creates
-C<LISTOP> optree fragments. C<newLISTOPn()> is a variadic function that takes
-a C<NULL>-terminated list of child op pointers, and constructs a new checked
-C<LISTOP> to contain them all. This is simpler than creating a new plain
-C<OP_LIST>, adding each child individually, and finally calling
-C<op_convert_list()> in most code fragments.
+C<dAX>, C<dITEMS> and hence C<dXSARGS> now declare C<AX> and C<items>
+as C<Stack_off_t> rather than C<SSize_t>. This reverts back to
+compatibility with pre-64-bit stack support for default builds of perl
+where C<Stack_off_t> is C<I32>. [GH #21782]
=item *
-The C<eval_sv()> API now accepts the C<G_USEHINTS> flag, which uses
-the hints such as strict and features from C<PL_curcop> instead of the
-default, which is to use default hints, e.g. no C<use vX.XX;>, no
-strict, default features.
-
-Beware if you use this flag in XS code: your evaluated code will need
-to support whatever strictness or features are in effect at the point
-your XS function is called.

-
-perl's -X flag disables all warnings globally, but «use 5.036» didn't
-respect that until now. [GH #21431]
+A new function is now available to C<XS> code, L<perlapi/sv_langinfo>.
+This provides the same information as the existing
+L<perlapi/Perl_langinfo8>, but returns an SV instead of a S<C<char *>>,
+so that programmers don't have to concern themselves with the UTF-8ness
+of the result. This new function is now the preferred interface for
+C<XS> code to the L<nl_langinfo(3)> C<libc> function. From Perl space,
+this information continues to be provided by the L<I18N::Langinfo>
+module.
