+=head1 NAME
+
+perl5276delta - what is new for perl v5.27.6
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.27.5 release and the 5.27.6
+release.
+
+If you are upgrading from an earlier release such as 5.27.4, first read
+L<perl5275delta>, which describes differences between 5.27.4 and 5.27.5.
+
+=head1 Core Enhancements
+
+=head2 Initialisation of aggregate state variables
+
+A persistent lexical array or hash variable can now be initialized,
+by an expression such as C<state @a = qw(x y z)>. Initialization of a
+list of persistent lexical variables is still not possible.
+
+=head2 Full-size inode numbers
+
+On platforms where inode numbers are of a type larger than perl's native
+integer numerical types, L<stat|perlfunc/stat> will preserve the full
+content of large inode numbers by returning them in the form of strings of
+decimal digits. Exact comparison of inode numbers can thus be achieved by
+comparing with C<eq> rather than C<==>. Comparison with C<==>, and other
+numerical operations (which are usually meaningless on inode numbers),
+work as well as they did before, which is to say they fall back to
+floating point, and ultimately operate on a fairly useless rounded inode
+number if the real inode number is too big for the floating point format.
+
+=head1 Incompatible Changes
+
+=head2 Yada-yada is now strictly a statement
+
+By the time of its initial stable release in Perl 5.12, the C<...>
+(yada-yada) operator was explicitly intended to serve as a statement,
+not an expression. However, the original implementation was confused
+on this point, leading to inconsistent parsing. The operator was
+accidentally accepted in a few situations where it did not serve as a
+complete statement, such as
+
+ ... . "foo";
+ ... if $a < $b;
+
+The parsing has now been made consistent, permitting yada-yada only as
+a statement. Affected code can use C<do{...}> to put a yada-yada into
+an arbitrary expression context.
+
+=head2 Subroutines no longer need typeglobs
+
+Perl 5.22.0 introduced an optimization allowing subroutines to be stored in
+packages as simple sub refs, not requiring a full typeglob (thus
+potentially saving large amounts of memeory). However, the optimization
+was flawed: it only applied to the main package.
+
+This optimization has now been extended to all packages. This may break
+compatibility with introspection code that looks inside stashes and expects
+everything in them to be a typeglob.
+
+When this optimization happens, the typeglob still notionally exists, so
+accessing it will cause the stash entry to be upgraded to a typeglob. The
+optimization does not apply to XSUBs or exported subroutines, and calling a
+method will undo it, since method calls cache things in typeglobs.
+
+(This change actually happened in perl 5.27.5 but was omitted from its perldelta.)
+
+[perl #129916] [perl #132252]
+
+=head2 Sort algorithm can no longer be specified
+
+Since Perl 5.8, the L<sort> pragma has had subpragmata C<_mergesort>,
+C<_quicksort>, and C<_qsort> that can be used to specify which algorithm
+perl should use to implement the L<sort|perlfunc/sort> builtin.
+This was always considered a dubious feature that might not last,
+hence the underscore spellings, and they were documented as not being
+portable beyond Perl 5.8. These subpragmata have now been deleted,
+and any attempt to use them is an error. The L<sort> pragma otherwise
+remains, and the algorithm-neutral C<stable> subpragma can be used to
+control sorting behaviour.
+[perl #119635]
+
+=head1 Performance Enhancements
+
+=over 4
+
+=item *
+
+Many string concatenation expressions are now considerably faster, due
+to the introduction internally of a C<multiconcat> opcode which combines
+multiple concatenations, and optionally a C<=> or C<.=>, into a single
+action. For example, apart from retrieving C<$s>, C<$a> and C<$b>, this
+whole expression is now handled as a single op:
+
+ $s .= "a=$a b=$b\n"
+
+As a special case, if the LHS of an assignment is a lexical variable or
+C<my $s>, the op itself handles retrieving the lexical variable, which
+is faster.
+
+In general, the more the expression includes a mix of constant strings and
+variable expressions, the longer the expression, and the more it mixes
+together non-utf8 and utf8 strings, the more marked the performance
+improvement. For example on a C<x86_64> system, this code has been
+benchmarked running four times faster:
+
+ my $s;
+ my $a = "ab\x{100}cde";
+ my $b = "fghij";
+ my $c = "\x{101}klmn";
+
+ for my $i (1..10_000_000) {
+ $s = "\x{100}wxyz";
+ $s .= "foo=$a bar=$b baz=$c";
+ }
+
+In addition, C<sprintf> expressions which have a constant format
+containing only C<%s> and C<%%> format elements, and which have a fixed
+number of arguments, are now also optimised into a C<multiconcat> op.
+
+=item *
+
+Subroutines in packages no longer need to be stored in typeglobs, saving
+large amounts of memory. See L</Subroutines no longer need typeglobs>
+under L</Incompatible Changes>, above.
+
+=back
+
+=head1 Modules and Pragmata
+
+Key highlights in this release across several modules:
+
+=head2 Removal of use vars
+
+The usage of C<use vars> has been discouraged since the introduction of C<our> in
+Perl 5.6.0. Where possible the usage of this pragma has now been removed from
+the Perl source code.
+
+This had a slight effect (for the better) on the output of WARNING_BITS in B::Deparse.
+
+=head2 Use of DynaLoader changed to XSLoader in many modules
+
+XSLoader is more modern, and most modules already require perl 5.6 or greater, so
+no functionality is lost by switching. In some cases, we have also made changes to
+the local implementation that may not be reflected in the version on CPAN due
+to a desire to maintain more backwards compatibility.

+
+Additionally, the following selected changes have been made:

+
+=item * L<perldiag/Variable length lookbehind not implemented in regex m/%s/>
+
+This now gives more ideas as to workarounds to the issue that was
+introduced in Perl 5.18 (but not documented explicitly in its perldelta)
+for the fact that some Unicode C</i> rules cause a few sequences such as
+
+ (?<!st)

+are currently only two code points that match this property U+200C (ZERO
+WIDTH NON-JOINER) and U+200D (ZERO WIDTH JOINER).

+
+A new optimisation phase has been added to the compiler,

+just before the peephole optimiser is run. This phase is not currently
+hookable.
+
+=item *
+
+An C<OP_MULTICONCAT> op has been added. At C<optimize_optree()> time, a
+chain of C<OP_CONCAT> and C<OP_CONST> ops, together optionally with an
+C<OP_STRINGIFY> and/or C<OP_SASSIGN>, are combined into a single
+C<OP_MULTICONCAT> op. The op is of type C<UNOP_AUX>, and the aux array
+contains the argument count, plus a pointer to a constant string and a set
+of segment lengths. For example with
+
+ my $x = "foo=$foo, bar=$bar\n";
+
+the constant string would be C<"foo=, bar=\n"> and the segment lengths
+would be (4,6,1). If the string contains characters such as C<\x80>, whose
+representation changes under utf8, two sets of strings plus lengths are
+precomputed and stored.
+
+=item *
+
+Direct access to L<C<PL_keyword_plugin>|perlapi/PL_keyword_plugin> is not
+safe in the presence of multithreading. A new
+L<C<wrap_keyword_plugin>|perlapi/wrap_keyword_plugin> function has been
+added to allow XS modules to safely define custom keywords even when
+loaded from a thread, analogous to L<C<PL_check>|perlapi/PL_check> /

+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.
-By the time of its initial stable release in Perl 5.12, the C<...>
-(yada-yada) operator was explicitly intended to serve as a statement,
-not an expression. However, the original implementation was confused
-on this point, leading to inconsistent parsing. The operator was
-accidentally accepted in a few situations where it did not serve as a
-complete statement, such as
+[ List each security issue as a =head2 entry ]
- ... . "foo";
- ... if $a < $b;
+=head1 Incompatible Changes
-The parsing has now been made consistent, permitting yada-yada only as
-a statement. Affected code can use C<do{...}> to put a yada-yada into

-=head2 Subroutines no longer need typeglobs
+ 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.
-Perl 5.22.0 introduced an optimization allowing subroutines to be stored in
-packages as simple sub refs, not requiring a full typeglob (thus
-potentially saving large amounts of memeory). However, the optimization
-was flawed: it only applied to the main package.
+[ List each incompatible change as a =head2 entry ]
-This optimization has now been extended to all packages. This may break
-compatibility with introspection code that looks inside stashes and expects
-everything in them to be a typeglob.
+=head1 Deprecations
-When this optimization happens, the typeglob still notionally exists, so
-accessing it will cause the stash entry to be upgraded to a typeglob. The
-optimization does not apply to XSUBs or exported subroutines, and calling a
-method will undo it, since method calls cache things in typeglobs.
+XXX Any deprecated features, syntax, modules etc. should be listed here.

+=head2 Module removals

-=head2 Sort algorithm can no longer be specified
+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.
-Since Perl 5.8, the L<sort> pragma has had subpragmata C<_mergesort>,
-C<_quicksort>, and C<_qsort> that can be used to specify which algorithm
-perl should use to implement the L<sort|perlfunc/sort> builtin.
-This was always considered a dubious feature that might not last,
-hence the underscore spellings, and they were documented as not being
-portable beyond Perl 5.8. These subpragmata have now been deleted,
-and any attempt to use them is an error. The L<sort> pragma otherwise
-remains, and the algorithm-neutral C<stable> subpragma can be used to
-control sorting behaviour.
-[perl #119635]
+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.
-=head1 Performance Enhancements
+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.

+=item XXX
-Many string concatenation expressions are now considerably faster, due
-to the introduction internally of a C<multiconcat> opcode which combines
-multiple concatenations, and optionally a C<=> or C<.=>, into a single
-action. For example, apart from retrieving C<$s>, C<$a> and C<$b>, this
-whole expression is now handled as a single op:
+XXX Note that deprecated modules should be listed here even if they are listed
+as an updated module in the L</Modules and Pragmata> section.
- $s .= "a=$a b=$b\n"
+=back
-As a special case, if the LHS of an assignment is a lexical variable or
-C<my $s>, the op itself handles retrieving the lexical variable, which
-is faster.
+[ List each other deprecation as a =head2 entry ]
-In general, the more the expression includes a mix of constant strings and
-variable expressions, the longer the expression, and the more it mixes
-together non-utf8 and utf8 strings, the more marked the performance
-improvement. For example on a C<x86_64> system, this code has been
-benchmarked running four times faster:
+=head1 Performance Enhancements
- my $s;
- my $a = "ab\x{100}cde";

- $s = "\x{100}wxyz";
- $s .= "foo=$a bar=$b baz=$c";
- }
+[ List each enhancement as an =item entry ]
-In addition, C<sprintf> expressions which have a constant format

-=head2 Removal of use vars
+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 usage of C<use vars> has been discouraged since the introduction of C<our> in
-Perl 5.6.0. Where possible the usage of this pragma has now been removed from
-the Perl source code.
+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.)
-This had a slight effect (for the better) on the output of WARNING_BITS in B::Deparse.
+[ Within each section, list entries as an =item entry ]
-=head2 Use of DynaLoader changed to XSLoader in many modules
-
-XSLoader is more modern, and most modules already require perl 5.6 or greater, so
-no functionality is lost by switching. In some cases, we have also made changes to
-the local implementation that may not be reflected in the version on CPAN due
-to a desire to maintain more backwards compatibility.
