=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 v5.11.5
=head1 DESCRIPTION
L<perl5114delta>, which describes differences between 5.11.3 and
5.11.4.
-=head1 Notice
-
-XXX Any important notices here
-
-=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 reports are welcome.
-
-
=head1 Core Enhancements
-XXX New core language features go here. Summarise user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
-
-=head1 New Platforms
+=head2 32-bit limit on substr arguments removed
-XXX List any platforms that this version of perl compiles on, that previous
-versions did not. These will either be enabled by new files in the F<hints/>
-directories, or new subdirectories and F<README> files at the top level of the
-source tree.
+The 32-bit limit on C<substr> arguments has now been removed. The full range
+of the system's signed and unsigned integers is now available for the C<pos>
+and C<len> arguments.
=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>, which prints stub
-entries to STDOUT. Results can be pasted in place of the '=head2' entries
-below. 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 C<is_lax> and C<is_strict> functions can now be optionally exported to the
+caller's namespace and are also now documented.

+Upgraded from version 1.94_53 to 1.94_55.
-=head1 Changes to Existing Documentation
+This module is also now built in a less specialized way, which resolves a

-XXX Changes which significantly change existing files in F<pod/> go here.
-Any changes to F<pod/perldiag.pod> should go in L</New or Changed Diagnostics>.

+Upgraded from version 0.44 to 0.46.
-=head1 Performance Enhancements
+=item C<Safe>
-XXX Changes which enhance performance without changing behaviour go here. There
-may well be none in a stable release.
+Upgraded from version 2.21 to 2.22.

+This resolves RT #72700, in which an exception thrown from a closure was

+The syntax C<unless (EXPR) BLOCK else BLOCK> is now documented as valid, as
+is the syntax C<unless (EXPR) BLOCK elsif (EXPR) BLOCK ... else BLOCK>,
+although actually using the latter may not be the best idea for the
+readability of your source code.

+=head2 Configuration improvements
-=item XXX-some-platform
+Support for SystemTap's C<dtrace> compatibility layer has been added and an
+issue with linking C<miniperl> has been fixed in the process.

+C<less -R> is now used instead of C<less> for C<groff>'s new usage of ANSI
+escape codes by setting C<$Config{less}> (and thereby C<$Config{pager}>,
+which fixes RT #72156.

+USE_PERL_ATOF is now reported in the compile-time options listed by the C<-V>
+switch.

+A panic caused by trying to load C<charnames> when the parser is already in

+has been fixed.

-=head1 New Tests
+Filehandles are now always blessed into C<IO::File>, which, together with
+some suitable manipulation of C<@IO::File::ISA>, fixes a breakage introduced
+in Perl 5.11.3 by a change that always blessed filehandles into C<IO::Handle>
+rather than checking for C<FileHandle> first.
-XXX Changes which create B<new> files in F<t/> go here. Changes to
-existing files in F<t/> aren't worth summarising, although the bugs that
-they represent may be.

+A change in C<warnings::register>'s behaviour in Perl 5.10.0 that wasn't

+RT #71504 is now fixed by simply skipping the tests that failed on OpenBSD

+loop.
-XXX Any changes specific to a particular platform. VMS and Win32 are the usual
