-Perl 5.25.12 is not binary compatible with earlier versions of Perl.
+Perl 5.26.0 is not binary compatible with earlier versions of Perl.
In other words, you will have to recompile your XS modules.
In general, you can usually safely upgrade from one version of Perl
libraries after 5.6.0, but not for executables. TODO?) One convenient
way to do this is by using a separate prefix for each version, such as
- sh Configure -Dprefix=/opt/perl5.25.12
+ sh Configure -Dprefix=/opt/perl5.26.0
-and adding /opt/perl5.25.12/bin to the shell PATH variable. Such users
+and adding /opt/perl5.26.0/bin to the shell PATH variable. Such users
may also wish to add a symbolic link /usr/local/bin/perl so that
scripts can still start with #!/usr/local/bin/perl.

=head1 DESCRIPTION
-The latest Perl release (5.25.12 as of this writing) builds without changes
+The latest Perl release (5.26.0 as of this writing) builds without changes
under all versions of Mac OS X from 10.3 "Panther" onwards.
In order to build your own version of Perl you will need 'make',
=item Additional Perl modules
- unzip perl_ste.zip -d f:/perllib/lib/site_perl/5.25.12/
+ unzip perl_ste.zip -d f:/perllib/lib/site_perl/5.26.0/
Same remark as above applies. Additionally, if this directory is not
one of directories on @INC (and @INC is influenced by C<PERLLIB_PREFIX>), you
choice. Once you have done so, use a command like the following to
unpack the archive:
- vmstar -xvf perl-5^.25^.12.tar
+ vmstar -xvf perl-5^.26^.0.tar
Then set default to the top-level source directory like so:
- set default [.perl-5^.25^.12]
+ set default [.perl-5^.26^.0]
and proceed with configuration as described in the next section.
Type "dmake" (or "nmake" if you are using that make).
This should build everything. Specifically, it will create perl.exe,
-perl525.dll at the perl toplevel, and various other extension dll's
+perl526.dll at the perl toplevel, and various other extension dll's
under the lib\auto directory. If the build fails for any reason, make
sure you have done the previous steps correctly.

-Some modules have been broken by the L<context stack rework|/Internal Changes>.
-These modules were relying on non-guaranteed implementation details in perl.
-Their maintainers have been informed, and should contact perl5-porters for
-advice if needed. Below is a subset of these modules:

-
-L<Coro> and perl v5.22.0 were already incompatible due to a change in the perl,

-
-If you find what you think is a bug, you might check the articles recently
-posted to the comp.lang.perl.misc newsgroup and the perl bug database at
-L<https://rt.perl.org/> . There may also be information at
-L<http://www.perl.org/> , the Perl Home Page.
-
-If you believe you have an unreported bug, please run the L<perlbug> program
-included with your release. Be sure to trim your bug down to a tiny but
-sufficient test case. Your bug report, along with the output of C<perl -V>,
-will be sent off to perlbug@perl.org to be analysed by the Perl porting team.
-

-
-=head1 Platform Support
-
-=head2 Platform-Specific Notes
-
-=over 4
-
-=item Windows
-
-=over 4
-
-=item *
-
-Support for compiling perl on Windows using Microsoft Visual Studio 2015
-(containing Visual C++ 14.0) has been added.
-
-This version of VC++ includes a completely rewritten C run-time library, some
-of the changes in which mean that work done to resolve a socket close() bug in
-perl #120091 and perl #118059 is not workable in its current state with this
-version of VC++. Therefore, we have effectively reverted that bug fix for
-VS2015 onwards on the basis that being able to build with VS2015 onwards is
-more important than keeping the bug fix. We may revisit this in the future to
-attempt to fix the bug again in a way that is compatible with VS2015.
-
-These changes do not affect compilation with GCC or with Visual Studio versions
-up to and including VS2013, i.e. the bug fix is retained (unchanged) for those
-compilers.
-
-Note that you may experience compatibility problems if you mix a perl built
-with GCC or VS E<lt>= VS2013 with XS modules built with VS2015, or if you mix a
-perl built with VS2015 with XS modules built with GCC or VS E<lt>= VS2013.
-Some incompatibility may arise because of the bug fix that has been reverted
-for VS2015 builds of perl, but there may well be incompatibility anyway because
-of the rewritten CRT in VS2015 (e.g. see discussion at
-http://stackoverflow.com/questions/30412951).

-=head1 Internal Changes
-
-=over 4
-
-=item *
-
-The C<op_class()> API function has been added. This is like the existing
-C<OP_CLASS()> macro, but can more accurately determine what struct an op
-has been allocated as. For example C<OP_CLASS()> might return
-C<OA_BASEOP_OR_UNOP> indicating that ops of this type are usually
-allocated as an C<OP> or C<UNOP>; while C<op_class()> will return
-C<OPclass_BASEOP> or C<OPclass_UNOP> as appropriate.
-
-=item *
-
-The output format of the C<op_dump()> function (as used by C<perl -Dx>)
-has changed: it now displays an "ASCII-art" tree structure, and shows more
-low-level details about each op, such as its address and class.
-

-
-=head1 Selected Bug Fixes
-
-=over 4
-
-=item *
-
-Attempting to use the deprecated variable C<$#> as the object in an
-indirect object method call could cause a heap use after free or
-buffer overflow. [perl #129274]
-
-=item *
-
-When checking for an indirect object method call in some rare cases
-the parser could reallocate the line buffer but then continue to use
-pointers to the old buffer. [perl #129190]
-
-=item *
-
-Supplying a glob as the format argument to L<perlfunc/formline> would
-cause an assertion failure. [perl #130722]
-
-=item *
-
-Code like C< $value1 =~ qr/.../ ~~ $value2 > would have the match
-converted into a qr// operator, leaving extra elements on the stack to
-confuse any surrounding expression. [perl #130705]
-
-=item *
-
-Since 5.24.0 in some obscure cases, a regex which included code blocks
-from multiple sources (e.g. via embedded via qr// objects) could end up
-with the wrong current pad and crash or give weird results. [perl #129881]
-
-=item *
-
-Occasionally C<local()>s in a code block within a patterns weren't being
-undone when the pattern matching backtracked over the code block.
-[perl #126697]
-
-=item *
-
-Using C<substr()> to modify a magic variable could access freed memory
-in some cases. [perl #129340]
-
-=item *
-
-Perl 5.25.9 was fixed so that under C<use utf8>, the entire Perl program
-is checked that the UTF-8 is wellformed. It turns out that several edge
-cases were missed, and are now fixed. [perl #126310] was the original
-ticket.

-
-Perl 5.25.10 represents approximately 4 weeks of development since Perl 5.25.9
-and contains approximately 12,000 lines of changes across 200 files from 25
-authors.
-
-Excluding auto-generated files, documentation and release tools, there were
-approximately 6,700 lines of changes to 130 .pm, .t, .c and .h files.
-
-Perl continues to flourish into its third decade thanks to a vibrant community
-of users and developers. The following people are known to have contributed the
-improvements that became Perl 5.25.10:

-It is with great sadness we note that Kip Hampton passed away. Probably

-core contributor to AxKit, ab XML server platform that became an Apache
-Foundation project. He was a frequent speaker in the early days at
-OSCON, and most recently at YAPC::NA in Madison. He was frequently on
-irc.perl.org as `ubu`, generally in the #axkit-dahut community, the
-group responsible for YAPC::NA Asheville in 2011.
-
-Kip and his constant contributions to the community will be greatly missed.

-=head1 NAME
-
-perl5251delta - what is new for perl v5.25.1
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.0 release and the 5.25.1
-release.
-
-If you are upgrading from an earlier release such as 5.24.0, first read
-L<perl5250delta>, which describes differences between 5.24.0 and 5.25.0.
-
-=head1 Core Enhancements
-
-=head2 POSIX::tmpnam() has been removed
-
-The fundamentally unsafe C<tmpnam()> interface was deprecated in
-Perl 5.22.0 and has now been removed. In its place you can use
-for example the L<File::Temp> interfaces.
-
-=head2 require ::Foo::Bar is now illegal.
-
-Formerly, C<require ::Foo::Bar> would try to read F</Foo/Bar.pm>. Now any
-bareword require which starts with a double colon dies instead.
-
-=head2 Unescaped literal C<"{"> characters in regular expression
-patterns are no longer permissible
-
-You have to now say something like C<"\{"> or C<"[{]"> to specify to
-match a LEFT CURLY BRACKET. This will allow future extensions to the
-language. This restriction is not enforced, nor are there current plans
-to enforce it, if the C<"{"> is the first character in the pattern.
-
-These have been deprecated since v5.16, with a deprecation message
-displayed starting in v5.22.
-
-=head2 Literal control character variable names are no longer permissible
-
-A variable name may no longer contain a literal control character under
-any circumstances. These previously were allowed in single-character
-names on ASCII platforms, but have been deprecated there since Perl
-v5.20. This affects things like C<$I<\cT>>, where I<\cT> is a literal
-control (such as a C<NAK> or C<NEGATIVE ACKNOWLEDGE> character) in the
-source code.
-
-=head2 C<qr//xx> is no longer permissible
-
-Using more than one C</x> regular expression pattern modifier on a
-single pattern is now forbidden. This is to allow a future enhancement
-to the language. This usage has been deprecated since v5.22.
-
-=head2 C<NBSP> is no longer permissible in C<\N{...}>
-
-The name of a character may no longer contain non-breaking spaces. It
-has been deprecated to do so since Perl v5.22.
-
-=head1 Performance Enhancements
-
-=over 4
-
-=item *
-
-Bareword constant strings are now permitted to take part in constant
-folding. They were originally exempted from constant folding in August 1999,
-during the development of Perl 5.6, to ensure that C<use strict "subs">
-would still apply to bareword constants. That has now been accomplished a
-different way, so barewords, like other constants, now gain the performance
-benefits of constant folding.
-
-This also means that void-context warnings on constant expressions of
-barewords now report the folded constant operand, rather than the operation;
-this matches the behaviour for non-bareword constants.

-=head1 NAME
-
-perl5252delta - what is new for perl v5.25.2
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.1 release and the 5.25.2
-release.
-
-If you are upgrading from an earlier release such as 5.25.0, first read
-L<perl5251delta>, which describes differences between 5.25.0 and 5.25.1.
-
-=head1 Core Enhancements
-
-=head2 Perl can now do default collation in UTF-8 locales on platforms
-that support it
-
-Some platforms natively do a reasonable job of collating and sorting in
-UTF-8 locales. Perl now works with those. For portability and full
-control, L<Unicode::Collate> is still recommended, but now you may
-not need to do anything special to get good-enough results, depending on
-your application. See
-L<perllocale/Category C<LC_COLLATE>: Collation: Text Comparisons and Sorting>.
-
-=head2 Better locale collation of strings containing embedded C<NUL>
-characters
-
-In locales that have multi-level character weights, these are now
-ignored at the higher priority ones. There are still some gotchas in
-some strings, though. See
-L<perllocale/Collation of strings containing embedded C<NUL> characters>.
-
-=head2 Lexical subroutines are no longer experimental
-
-Using the C<lexical_subs> feature no longer emits a warning. Existing code that disables the C<experimental::lexical_subs> warning category that the
-feature previously used will continue to work. The C<lexical_subs> feature
-has no effect; all Perl code can use lexical subroutines, regardless of
-what feature declarations are in scope.
-
-=head2 C<CORE> subroutines for hash and array functions callable via
-reference
-
-The hash and array functions in the C<CORE> namespace--C<keys>, C<each>,
-C<values>, C<push>, C<pop>, C<shift>, C<unshift> and C<splice>--, can now
-be called with ampersand syntax (C<&CORE::keys(\%hash>) and via reference
-(C<< my $k = \&CORE::keys; $k->(\%hash) >>). Previously they could only be
-used when inlined.
-
-=head1 Security
-
-=head2 C<-Di> switch is now required for PerlIO debugging output
-
-Previously PerlIO debugging output would be sent to the file specified
-by the C<PERLIO_DEBUG> environment variable if perl wasn't running
-setuid and the C<-T> or C<-t> switches hadn't been parsed yet.
-
-If perl performed output at a point where it hadn't yet parsed its
-switches this could result in perl creating or overwriting the file
-named by C<PERLIO_DEBUG> even when the C<-T> switch had been supplied.
-
-Perl now requires the C<-Di> switch to produce PerlIO debugging
-output. By default this is written to C<stderr>, but can optionally
-be redirected to a file by setting the C<PERLIO_DEBUG> environment
-variable.
-
-If perl is running setuid or the C<-T> switch has supplied
-C<PERLIO_DEBUG> is ignored and the debugging output is sent to
-C<stderr> as for any other C<-D> switch.
-
-=head1 Incompatible Changes
-
-=head2 C<keys> returned from an lvalue subroutine
-
-C<keys> returned from an lvalue subroutine can no longer be assigned
-to in list context.
-
- sub foo : lvalue { keys(%INC) }
- (foo) = 3; # death
- sub bar : lvalue { keys(@_) }
- (bar) = 3; # also an error
-
-This makes the lvalue sub case consistent with C<(keys %hash) = ...> and
-C<(keys @_) = ...>, which are also errors. [perl #128187]

-=head1 NAME
-
-perl5253delta - what is new for perl v5.25.3
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.2 release and the 5.25.3
-release.
-
-If you are upgrading from an earlier release such as 5.25.1, first read
-L<perl5252delta>, which describes differences between 5.25.1 and 5.25.2.
-
-=head1 Core Enhancements
-
-=head2 Unicode 9.0 is now supported
-
-A list of changes is at L<http://www.unicode.org/versions/Unicode9.0.0/>.
-Modules that are shipped with core Perl but not maintained by p5p do not
-necessarily support Unicode 9.0. L<Unicode::Normalize> does work on 9.0.
-
-=head2 Use of C<\p{I<script>}> uses the improved Script_Extensions property
-
-Unicode 6.0 introduced an improved form of the Script (C<sc>) property, and
-called it Script_Extensions (C<scx>). As of now, Perl uses this improved
-version when a property is specified as just C<\p{I<script>}>. The meaning of
-compound forms, like C<\p{sc=I<script>}> are unchanged. This should make
-programs be more accurate when determining if a character is used in a given
-script, but there is a slight chance of breakage for programs that very
-specifically needed the old behavior. See L<perlunicode/Scripts>.
-
-=head2 Declaring a reference to a variable
-
-As an experimental feature, Perl now allows the referencing operator to come
-after L<C<my()>|perlfunc/my>, L<C<state()>|perlfunc/state>,
-L<C<our()>|perlfunc/our>, or L<C<local()>|perlfunc/local>. This syntax must
-be enabled with C<use feature 'declared_refs'>. It is experimental, and will
-warn by default unless C<no warnings 'experimental::refaliasing'> is in effect.
-It is intended mainly for use in assignments to references. For example:
-
- use experimental 'refaliasing', 'declared_refs';
- my \$a = \$b;
-
-See L<perlref/Assigning to References> for slightly more detail.
-
-=head1 Incompatible Changes
-
-=head2 C<${^ENCODING}> has been removed
-
-Consequently, the L<encoding> pragma's default mode is no longer supported. If
-you still need to write your source code in encodings other than UTF-8, use a
-source filter such as L<Filter::Encoding> on CPAN or L<encoding>'s C<Filter>
-option.
-
-=head2 C<scalar(%hash)> return signature changed
-
-The value returned for C<scalar(%hash)> will no longer show information about
-the buckets allocated in the hash. It will simply return the count of used
-keys. It is thus equivalent to C<0+keys(%hash)>.
-
-A form of backwards compatibility is provided via C<Hash::Util::bucket_ratio()>
-which provides the same behavior as C<scalar(%hash)> provided prior to Perl
-5.25.

-
-Problems with in-place array sorts: code like C<@a = sort { ... } @a>,
-where the source and destination of the sort are the same plain array, are
-optimised to do less copying around. Two side-effects of this optimisation
-were that the contents of C<@a> as visible to to sort routine were
-partially sorted, and under some circumstances accessing C<@a> during the
-sort could crash the interpreter. Both these issues have been fixed, and
-Sort functions see the original value of C<@a>.
-
-=item *
-
-Non-ASCII string delimiters are now reported correctly in error messages
-for unterminated strings. [perl #128701]
-
-=item *
-
-C<pack("p", ...)> used to emit its warning ("Attempt to pack pointer to
-temporary value") erroneously in some cases, but has been fixed.
-
-=item *
-
-C<@DB::args> is now exempt from "used once" warnings. The warnings only
-occurred under B<-w>, because F<warnings.pm> itself uses C<@DB::args>
-multiple times.
-
-=item *
-
-The use of built-in arrays or hash slices in a double-quoted string no
-longer issues a warning ("Possible unintended interpolation...") if the
-variable has not been mentioned before. This affected code like
-C<qq|@DB::args|> and C<qq|@SIG{'CHLD', 'HUP'}|>. (The special variables
-C<@-> and C<@+> were already exempt from the warning.)
-
-=item *
-
-C<gethostent> and similar functions now perform a null check internally, to
-avoid crashing with torsocks. This was a regression from 5.22. [perl
-#128740]
-

-
-C<defined *{'!'}>, C<defined *{'['}>, and C<defined *{'-'}> no longer leak
-memory if the typeglob in question has never been accessed before.

-In 5.25.4 fchown() was changed not to accept negative one as an argument
-because in some platforms that is an error. However, in some other platforms
-that is an acceptable argument. This change has been reverted [perl #128967].
-

-
-Mentioning the same constant twice in a row (which is a syntax error) no
-longer fails an assertion under debugging builds. This was a regression
-from 5.20. [perl #126482]
-
-=item *
-
-Many issues relating to C<printf "%a"> of hexadecimal floating point
-were fixed. In addition, the "subnormals" (formerly known as "denormals")
-floating point anumbers are now supported both with the plain IEEE 754
-floating point numbers (64-bit or 128-bit) and the x86 80-bit
-"extended precision". Note that subnormal hexadecimal floating
-point literals will give a warning about "exponent underflow".

-
-A regression from the previous development release, 5.23.3, where
-compiling a regular expression could crash the interpreter has been
-fixed. [perl #128686].
-
-=item *
-
-Use of a string delimiter whose code point is above 2**31 now works
-correctly on platforms that allow this. Previously, certain characters,
-due to truncation, would be confused with other delimiter characters
-with special meaning (such as C<?> in C<m?...?>), resulting
-in inconsistent behaviour. Note that this is non-portable,
-and is based on Perl's extension to UTF-8, and is probably not
-displayable nor enterable by any editor. [perl #128738]

-C<@{x> followed by a newline where C<x> represents a control or non-ASCII
-character no longer produces a garbled syntax error message or a crash.

-perl5255delta - what is new for perl v5.25.5
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.4 release and the 5.25.5
-release.
-
-If you are upgrading from an earlier release such as 5.25.3, first read
-L<perl5254delta>, which describes differences between 5.25.3 and 5.25.4.

-=head1 Security
-
-=head2 "Escaped" colons and relative paths in PATH
-
-On Unix systems, Perl treats any relative paths in the PATH environment
-variable as tainted when starting a new process. Previously, it was
-allowing a backslash to escape a colon (unlike the OS), consequently
-allowing relative paths to be considered safe if the PATH was set to
-something like C</\:.>. The check has been fixed to treat C<.> as tainted
-in that example.

-

-
-Invalid assignments to a reference constructor (e.g., C<\eval=time>) could
-sometimes crash in addition to giving a syntax error. [perl #125679]
-
-=item *
-
-The parser could sometimes crash if a bareword came after C<evalbytes>.
-[perl #129196]
-
-=item *
-
-Autoloading via a method call would warn erroneously ("Use of inherited
-AUTOLOAD for non-method") if there was a stub present in the package into
-which the invocant had been blessed. The warning is no longer emitted in
-such circumstances. [perl #47047]
-
-=item *
-
-A sub containing with a "forward" declaration with the same name (e.g.,
-C<sub c { sub c; }>) could sometimes crash or loop infinitely. [perl
-#129090]
-
-=item *
-
-The use of C<splice> on arrays with nonexistent elements could cause other
-operators to crash. [perl #129164]
-
-=item *
-
-Fixed case where C<re_untuit_start> will overshoot the length of a utf8
-string. [perl #129012]
-
-=item *
-
-Handle C<CXt_SUBST> better in C<Perl_deb_stack_all>, previously it wasn't
-checking that the I<current> C<cx> is the right type, and instead was always
-checking the base C<cx> (effectively a noop). [perl #129029]
-
-=item *
-
-Fixed two possible use-after-free bugs in C<Perl_yylex>. C<Perl_yylex>
-maintains up to two pointers into the parser buffer, one of which can
-become stale under the right conditions. [perl #129069]
-
-=item *
-
-Fixed a crash with C<s///l> where it thought it was dealing with UTF-8
-when it wasn't. [perl #129038]
-

-
-Fixed place where regex was not setting the syntax error correctly.
-[perl #129122]
-
-=item *
-
-The C<&.> operator (and the C<&> operator, when it treats its arguments as
-strings) were failing to append a trailing null byte if at least one string
-was marked as utf8 internally. Many code paths (system calls, regexp
-compilation) still expect there to be a null byte in the string buffer
-just past the end of the logical string. An assertion failure was the
-result. [perl #129287]
-
-=item *
-
-Check C<pack_sockaddr_un()>'s return value because C<pack_sockaddr_un()>
-silently truncates the supplied path if it won't fit into the C<sun_path>
-member of C<sockaddr_un>. This may change in the future, but for now
-check the path in theC<sockaddr> matches the desired path, and skip if
-it doesn't. [perl #128095]

-
-The function C<L<perlapi/utf8n_to_uvchr>> has been changed to not
-abandon searching for other malformations when the first one is

-instead of just one.
-
-=item *
-
-A new function, C<L<perlapi/utf8n_to_uvchr_error>>, has been added for
-use by modules that need to know the details of UTF-8 malformations
-beyond pass/fail. Previously, the only ways to know why a sequence was
-ill-formed was to capture and parse the generated diagnostics, or to do
-your own analysis.
-
-=item *
-
-Several new functions for handling Unicode have been added to the API:
-C<L<perlapi/is_strict_utf8_string>>,
-C<L<perlapi/is_c9strict_utf8_string>>,

-These functions are all extensions of the C<is_utf8_string_*()> functions,
-that apply various restrictions to the UTF-8 recognized as valid.

-A new API function C<sv_setvpv_bufsize()> allows simultaneously setting the
-length and allocated size of the buffer in an C<SV>, growing the buffer if
-necessary.

-
-A new API macro C<SvPVCLEAR()> sets its C<SV> argument to an empty string,
-like Perl-space C<$x = ''>, but with several optimisations.
-
-=item *
-
-All parts of the internals now agree that the C<sassign> op is a C<BINOP>;
-previously it was listed as a C<BASEOP> in F<regen/opcodes>, which meant
-that several parts of the internals had to be special-cased to accommodate
-it. This oddity's original motivation was to handle code like C<$x ||= 1>;
-that is now handled in a simpler way.
-
-=item *
-
-Several new internal C macros have been added that take a string literal as
-arguments, alongside existing routines that take the equivalent value as two
-arguments, a character pointer and a length. The advantage of this is that
-the length of the string is calculated automatically, rather than having to
-be done manually. These routines are now used where appropriate across the
-entire codebase.

-The code in F<gv.c> that determines whether a variable has a special meaning

-=head1 Core Enhancements
-
-=head2 Indented Here-documents
-
-This adds a new modifier '~' to here-docs that tells the parser
-that it should look for /^\s*$DELIM\n/ as the closing delimiter.
-
-These syntaxes are all supported:
-
- <<~EOF;
- <<~\EOF;
- <<~'EOF';
- <<~"EOF";
- <<~`EOF`;
- <<~ 'EOF';
- <<~ "EOF";
- <<~ `EOF`;
-
-The '~' modifier will strip, from each line in the here-doc, the
-same whitespace that appears before the delimiter.
-
-Newlines will be copied as is, and lines that don't include the
-proper beginning whitespace will cause perl to croak.
-
-For example:
-
- if (1) {
- print <<~EOF;
- Hello there
- EOF
- }
-
-prints "Hello there\n" with no leading whitespace.
-
-=head2 '.' and @INC
-
-Perl now provides a way to build perl without C<.> in @INC by default. If you
-want this feature, you can build with -Ddefault_inc_excludes_dot
-
-Because the testing / make process for perl modules do not function well with
-C<.> missing from @INC, Perl now supports the environment variable
-PERL_USE_UNSAFE_INC=1 which makes Perl behave as it previously did, returning
-C<.> to @INC in all child processes.
-
-WARNING: PERL_USE_UNSAFE_INC has been provided during the perl 5.25 development
-cycle and is not guaranteed to function in perl 5.26.
-
-=head2 create a safer utf8_hop() called utf8_hop_safe()
-
-Unlike utf8_hop(), utf8_hop_safe() won't navigate before the beginning or after
-the end of the supplied buffer.
-
-=head2 Fix taint handling in list assignment
-
-commit v5.25.6-79-gb09ed99 reworked list assignment, and
-accidentally broke taint handling at the same time.
-
-=head2 @{^CAPTURE}, %{^CAPTURE}, and %{^CAPTURE_ALL}
-
-@{^CAPTURE} exposes the capture buffers of the last match as an array. So $1 is
-${^CAPTURE}[0].
-
-%{^CAPTURE} is the equivalent to %+ (ie named captures)
-
-%{^CAPTURE_ALL} is the equivalent to %- (ie all named captures).
-
-=head2 op.c: silence compiler warning in fold_constants()
-
- op.c: In function ‘S_fold_constants’:
- op.c:4374:28: warning: argument ‘o’ might be clobbered by ‘longjmp’ or ‘vfork’ [-Wclobbered]
- S_fold_constants(pTHX_ OP *o)
- ^
-
-This warning has been silenced.

-returns C<($a,$b,$c)>. This can be seen in the following:
-
- sub inc { $_++ for @_ }
- inc(($a,$b,@c,$d) = (10))

-
-perl5258delta - what is new for perl v5.25.8
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.7 release and the 5.25.8
-release.
-
-If you are upgrading from an earlier release such as 5.25.6, first read
-L<perl5257delta>, which describes differences between 5.25.6 and 5.25.7.
-
-=head1 Core Enhancements
-
-=head2 New Hash Function For 64-bit Builds
-
-We have switched to a hybrid hash function to better balance
-performance for short and long keys.
-
-For short keys, 16 bytes and under, we use an optimised variant of
-One At A Time Hard, and for longer keys we use Siphash 1-3. For very
-long keys this is a big improvement in performance. For shorter keys
-there is a modest improvement.
-
-=head1 Performance Enhancements
-
-=over 4
-
-=item * New Faster Hash Function on 64 bit builds
-
-We use a different hash function for short and long keys. This should
-improve performance and security, especially for long keys.
-
-=item * readline is faster
-
-Reading from a file line-by-line with C<readline()> or C<< E<lt>E<gt> >> should
-now typically be faster due to a better implementation of the code that
-searches for the next newline character.

-=head1 NAME
-
-perl5259delta - what is new for perl v5.25.9
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.25.8 release and the 5.25.9
-release.
-
-If you are upgrading from an earlier release such as 5.25.7, first read
-L<perl5258delta>, which describes differences between 5.25.7 and 5.25.8.
-
-=head1 Core Enhancements
-
-=head2 New regular expression modifier C</xx>
-
-Specifying two C<x> characters to modify a regular expression pattern
-does everything that a single one does, but additionally TAB and SPACE
-characters within a bracketed character class are generally ignored and
-can be added to improve readability, like
-S<C</[ ^ A-Z d-f p-x ]/xx>>. Details are at
-L<perlre/E<sol>x and E<sol>xx>.
-
-=head1 Deprecations
-
-=head2 String delimiters that aren't stand-alone graphemes are now deprecated
-
-In order for Perl to eventually allow string delimiters to be Unicode
-grapheme clusters (which look like a single character, but may be
-a sequence of several ones), we have to stop allowing a single char
-delimiter that isn't a grapheme by itself. These are unlikely to exist
-in actual code, as they would typically display as attached to the
-character in front of them.
-
-=head1 Performance Enhancements
-
-=over 4
-
-=item *
-
-A hash in boolean context is now sometimes faster, e.g.
-
- if (!%h) { ... }
-
-This was already special-cased, but some cases were missed, and even the
-ones which weren't have been improved.
-
-=item *
-
-Several other ops may now also be faster in boolean context.

-

-
-=item *
-
-New versions of macros like C<isALPHA_utf8> and C<toLOWER_utf8> have
-been added, each with the
-suffix C<_safe>, like C<isSPACE_utf8_safe>. These take an extra
-parameter, giving an upper limit of how far into the string it is safe
-to read. Using the old versions could cause attempts to read beyond the
-end of the input buffer if the UTF-8 is not well-formed, and their use
-now raises a deprecation warning. Details are at
-L<perlapi/Character classification>.
-
-=item *
-
-Calling macros like C<isALPHA_utf8> on malformed UTF-8 have issued a
-deprecation warning since Perl v5.18. They now die.
-Similarly, macros like C<toLOWER_utf8> on malformed UTF-8 now die.
-
-=item *
-
-Calling the functions C<utf8n_to_uvchr> and its derivatives, while
-passing a string length of 0 is now asserted against in DEBUGGING
-builds, and otherwise returns the Unicode REPLACEMENT CHARACTER. If
-you have nothing to decode, you shouldn't call the decode function.
-
-=item *
-
-The functions C<utf8n_to_uvchr> and its derivatives now return the
-Unicode REPLACEMENT CHARACTER if called with UTF-8 that has the overlong
-malformation, and that malformation is allowed by the input parameters.
-This malformation is where the UTF-8 looks valid syntactically, but
-there is a shorter sequence that yields the same code point. This has
-been forbidden since Unicode version 3.1.
-
-=item *
-
-The functions C<utf8n_to_uvchr> and its derivatives now accept an input
-flag to allow the overflow malformation. This malformation is when the
-UTF-8 may be syntactically valid, but the code point it represents is
-not capable of being represented in the word length on the platform.
-What "allowed" means in this case is that the function doesn't return an
-error, and advances the parse pointer to beyond the UTF-8 in question,
-but it returns the Unicode REPLACEMENT CHARACTER as the value of the
-code point (since the real value is not representable).

-
-Under C<use utf8>, the entire Perl program is now checked that the UTF-8
-is wellformed. This resolves [perl #126310].
-
-=item *
-
-The range operator C<..> on strings now handles its arguments correctly when in
-the scope of the L<< C<unicode_strings>|feature/"The 'unicode_strings' feature" >>
-feature. The previous behaviour was sufficiently unexpected that we believe no
-correct program could have made use of it.
-

-
-The S<split> operator did not ensure enough space was allocated for
-its return value in scalar context. It could then write a single
-pointer immediately beyond the end of the memory block allocated for
-the stack. [perl #130262]

=head1 NAME
-perldelta - what is new for perl v5.25.12
+perldelta - what is new for perl v5.26.0
=head1 DESCRIPTION
-This document describes differences between the 5.25.11 release and the 5.25.12
+This document describes the differences between the 5.24.0 release and the
+5.26.0 release.
+
+=head1 Notice
+
+This release includes three updates with widespread effects:
+
+=over 4
+
+=item * C<"."> no longer in C<@INC>
+
+For security reasons, the current directory (C<".">) is no longer included
+by default at the end of the module search path (C<@INC>). This may have
+widespread implications for the building, testing and installing of
+modules, and for the execution of scripts. See the section
+L<< Removal of the current directory (C<".">) from C<@INC> >>
+for the full details.
+
+=item * C<do> may now warn
+
+C<do> now gives a deprecation warning when it fails to load a file which
+it would have loaded had C<"."> been in C<@INC>.
+
+=item * In regular expression patterns, a literal left brace C<"{">
+should be escaped
+
+See L</Unescaped literal C<"{"> characters in regular expression patterns are no longer permissible>.
+
+=back
+
+=head1 Core Enhancements
+
+=head2 Lexical subroutines are no longer experimental
+
+Using the C<lexical_subs> feature introduced in v5.18 no longer emits a warning. Existing
+code that disables the C<experimental::lexical_subs> warning category
+that the feature previously used will continue to work. The
+C<lexical_subs> feature has no effect; all Perl code can use lexical
+subroutines, regardless of what feature declarations are in scope.
+
+=head2 Indented Here-documents
+
+This adds a new modifier C<"~"> to here-docs that tells the parser
+that it should look for C</^\s*$DELIM\n/> as the closing delimiter.
+
+These syntaxes are all supported:
+
+ <<~EOF;
+ <<~\EOF;
+ <<~'EOF';
+ <<~"EOF";
+ <<~`EOF`;
+ <<~ 'EOF';
+ <<~ "EOF";
+ <<~ `EOF`;
+
+The C<"~"> modifier will strip, from each line in the here-doc, the
+same whitespace that appears before the delimiter.
+
+Newlines will be copied as-is, and lines that don't include the
+proper beginning whitespace will cause perl to croak.
+
+For example:
+
+ if (1) {
+ print <<~EOF;
+ Hello there
+ EOF
+ }
+
+prints "Hello there\n" with no leading whitespace.
+
+=head2 New regular expression modifier C</xx>
+
+Specifying two C<"x"> characters to modify a regular expression pattern
+does everything that a single one does, but additionally TAB and SPACE
+characters within a bracketed character class are generally ignored and
+can be added to improve readability, like
+S<C</[ ^ A-Z d-f p-x ]/xx>>. Details are at
+L<perlre/E<sol>x and E<sol>xx>.
+
+=head2 C<@{^CAPTURE}>, C<%{^CAPTURE}>, and C<%{^CAPTURE_ALL}>
+
+C<@{^CAPTURE}> exposes the capture buffers of the last match as an
+array. So C<$1> is C<${^CAPTURE}[0]>. This is a more efficient equivalent
+to code like C<substr($matched_string,$-[0],$+[0]-$-[0])>, and you don't
+have to keep track of the C<$matched_string> either. This variable has no
+single character equivalent. Note that, like the other regex magic variables,
+the contents of this variable is dynamic; if you wish to store it beyond
+the lifetime of the match you must copy it to another array.
+
+C<%{^CAPTURE}> is equivalent to C<%+> (I<i.e.>, named captures). Other than
+being more self-documenting there is no difference between the two forms.
+
+C<%{^CAPTURE_ALL}> is equivalent to C<%-> (I<i.e.>, all named captures).
+Other than being more self-documenting there is no difference between the
+two forms.
+
+=head2 Declaring a reference to a variable
+
+As an experimental feature, Perl now allows the referencing operator to come
+after L<C<my()>|perlfunc/my>, L<C<state()>|perlfunc/state>,
+L<C<our()>|perlfunc/our>, or L<C<local()>|perlfunc/local>. This syntax must
+be enabled with C<use feature 'declared_refs'>. It is experimental, and will
+warn by default unless C<no warnings 'experimental::refaliasing'> is in effect.
+It is intended mainly for use in assignments to references. For example:
+
+ use experimental 'refaliasing', 'declared_refs';
+ my \$a = \$b;
+
+See L<perlref/Assigning to References> for more details.
+
+=head2 Unicode 9.0 is now supported
+
+A list of changes is at L<http://www.unicode.org/versions/Unicode9.0.0/>.
+Modules that are shipped with core Perl but not maintained by p5p do not
+necessarily support Unicode 9.0. L<Unicode::Normalize> does work on 9.0.
+
+=head2 Use of C<\p{I<script>}> uses the improved Script_Extensions property
+
+Unicode 6.0 introduced an improved form of the Script (C<sc>) property, and
+called it Script_Extensions (C<scx>). Perl now uses this improved
+version when a property is specified as just C<\p{I<script>}>. This
+should make programs more accurate when determining if a character is
+used in a given script, but there is a slight chance of breakage for
+programs that very specifically needed the old behavior. The meaning of
+compound forms, like C<\p{sc=I<script>}> are unchanged. See
+L<perlunicode/Scripts>.
+
+=head2 Perl can now do default collation in UTF-8 locales on platforms
+that support it
+
+Some platforms natively do a reasonable job of collating and sorting in
+UTF-8 locales. Perl now works with those. For portability and full
+control, L<Unicode::Collate> is still recommended, but now you may
+not need to do anything special to get good-enough results, depending on
+your application. See
+L<perllocale/Category C<LC_COLLATE>: Collation: Text Comparisons and Sorting>.
+
+=head2 Better locale collation of strings containing embedded C<NUL>
+characters
+
+In locales that have multi-level character weights, C<NUL>s are now
+ignored at the higher priority ones. There are still some gotchas in
+some strings, though. See
+L<perllocale/Collation of strings containing embedded C<NUL> characters>.
+
+=head2 C<CORE> subroutines for hash and array functions callable via
+reference
+
+The hash and array functions in the C<CORE> namespace (C<keys>, C<each>,
+C<values>, C<push>, C<pop>, C<shift>, C<unshift> and C<splice>) can now
+be called with ampersand syntax (C<&CORE::keys(\%hash>) and via reference
+(C<< my $k = \&CORE::keys; $k-E<gt>(\%hash) >>). Previously they could only be
+used when inlined.
+
+=head2 New Hash Function For 64-bit Builds
+
+We have switched to a hybrid hash function to better balance
+performance for short and long keys.
+
+For short keys, 16 bytes and under, we use an optimised variant of
+One At A Time Hard, and for longer keys we use Siphash 1-3. For very
+long keys this is a big improvement in performance. For shorter keys
+there is a modest improvement.
+
+=head1 Security
+
+=head2 Removal of the current directory (C<".">) from C<@INC>
+
+The perl binary includes a default set of paths in C<@INC>. Historically
+it has also included the current directory (C<".">) as the final entry,
+unless run with taint mode enabled (C<perl -T>). While convenient, this has
+security implications: for example, where a script attempts to load an
+optional module when its current directory is untrusted (such as F</tmp>),
+it could load and execute code from under that directory.
+
+Starting with v5.26, C<"."> is always removed by default, not just under
+tainting. This has major implications for installing modules and executing
+scripts.
+
+The following new features have been added to help ameliorate these
+issues.
+
+=over
+
+=item * F<Configure -Udefault_inc_excludes_dot>
+
+There is a new F<Configure> option, C<default_inc_excludes_dot> (enabled
+by default) which builds a perl executable without C<".">; unsetting this
+option using C<-U> reverts perl to the old behaviour. This may fix your
+path issues but will reintroduce all the security concerns, so don't
+build a perl executable like this unless you're I<really> confident that
+such issues are not a concern in your environment.
+
+=item * C<PERL_USE_UNSAFE_INC>
+
+There is a new environment variable recognised by the perl interpreter.
+If this variable has the value 1 when the perl interpreter starts up,
+then C<"."> will be automatically appended to C<@INC> (except under tainting).
+
+This allows you restore the old perl interpreter behaviour on a
+case-by-case basis. But note that this is intended to be a temporary crutch,
+and this feature will likely be removed in some future perl version.
+It is currently set by the C<cpan> utility and C<Test::Harness> to
+ease installation of CPAN modules which have not been updated to handle the
+lack of dot. Once again, don't use this unless you are sure that this
+will not reintroduce any security concerns.
+
+=item * A new deprecation warning issued by C<do>.
+
+While it is well-known that C<use> and C<require> use C<@INC> to search
+for the file to load, many people don't realise that C<do "file"> also
+searches C<@INC> if the file is a relative path. With the removal of C<".">,
+a simple C<do "file.pl"> will fail to read in and execute C<file.pl> from
+the current directory. Since this is commonly expected behaviour, a new
+deprecation warning is now issued whenever C<do> fails to load a file which
+it otherwise would have found if a dot had been in C<@INC>.
+
+=back
+
+Here are some things script and module authors may need to do to make
+their software work in the new regime.
+
+=over
+
+=item * Script authors
+
+If the issue is within your own code (rather than within included
+modules), then you have two main options. Firstly, if you are confident
+that your script will only be run within a trusted directory (under which
+you expect to find trusted files and modules), then add C<"."> back into the
+path; I<e.g.>:
+
+ BEGIN {
+ my $dir = "/some/trusted/directory";
+ chdir $dir or die "Can't chdir to $dir: $!\n";
+ # safe now
+ push @INC, '.';
+ }
+
+ use "Foo::Bar"; # may load /some/trusted/directory/Foo/Bar.pm
+ do "config.pl"; # may load /some/trusted/directory/config.pl
+
+On the other hand, if your script is intended to be run from within
+untrusted directories (such as F</tmp>), then your script suddenly failing
+to load files may be indicative of a security issue. You most likely want
+to replace any relative paths with full paths; for example,
+
+ do "foo_config.pl"
+
+might become
+
+ do "$ENV{HOME}/foo_config.pl"
+
+If you are absolutely certain that you want your script to load and
+execute a file from the current directory, then use a C<./> prefix; for
+example:
+
+ do "./foo_config.pl"
+
+=item * Installing and using CPAN modules
+
+If you install a CPAN module using an automatic tool like C<cpan>, then
+this tool will itself set the C<PERL_USE_UNSAFE_INC> environment variable
+while building and testing the module, which may be sufficient to install
+a distribution which hasn't been updated to be dot-aware. If you want to
+install such a module manually, then you'll need to replace the
+traditional invocation:
+
+ perl Makefile.PL && make && make test && make install
+
+with something like
+
+ (export PERL_USE_UNSAFE_INC=1; \
+ perl Makefile.PL && make && make test && make install)
+
+Note that this only helps build and install an unfixed module. It's
+possible for the tests to pass (since they were run under
+C<PERL_USE_UNSAFE_INC=1>), but for the module itself to fail to perform
+correctly in production. In this case, you may have to temporarily modify
+your script until a fixed version of the module is released.
+For example:
+
+ use Foo::Bar;
+ {
+ local @INC = (@INC, '.');
+ # assuming read_config() needs '.' in @INC
+ $config = Foo::Bar->read_config();
+ }
+
+This is only rarely expected to be necessary. Again, if doing this,
+assess the resultant risks first.
+
+=item * Module Authors
+
+If you maintain a CPAN distribution, it may need updating to run in
+a dotless environment. Although C<cpan> and other such tools will
+currently set the C<PERL_USE_UNSAFE_INC> during module build, this is a
+temporary workaround for the set of modules which rely on C<"."> being in
+C<@INC> for installation and testing, and this may mask deeper issues. It
+could result in a module which passes tests and installs, but which
+fails at run time.
+
+During build, test, and install, it will normally be the case that any perl
+processes will be executing directly within the root directory of the
+untarred distribution, or a known subdirectory of that, such as F<t/>. It
+may well be that F<Makefile.PL> or F<t/foo.t> will attempt to include
+local modules and configuration files using their direct relative
+filenames, which will now fail.
+
+However, as described above, automatic tools like F<cpan> will (for now)
+set the C<PERL_USE_UNSAFE_INC> environment variable, which introduces
+dot during a build.
+
+This makes it likely that your existing build and test code will work, but
+this may mask issues with your code which only manifest when used after
+install. It is prudent to try and run your build process with that
+variable explicitly disabled:
+
+ (export PERL_USE_UNSAFE_INC=0; \
+ perl Makefile.PL && make && make test && make install)
+
+This is more likely to show up any potential problems with your module's
+build process, or even with the module itself. Fixing such issues will
+ensure both that your module can again be installed manually, and that
+it will still build once the C<PERL_USE_UNSAFE_INC> crutch goes away.
+
+When fixing issues in tests due to the removal of dot from C<@INC>,
+reinsertion of dot into C<@INC> should be performed with caution, for this
+too may suppress real errors in your runtime code. You are encouraged
+wherever possible to apply the aforementioned approaches with explicit
+absolute/relative paths, or to relocate your needed files into a
+subdirectory and insert that subdirectory into C<@INC> instead.
+
+If your runtime code has problems under the dotless C<@INC>, then the comments
+above on how to fix for script authors will mostly apply here too. Bear in
+mind though that it is considered bad form for a module to globally add a dot to
+C<@INC>, since it introduces both a security risk and hides issues of
+accidentally requiring dot in C<@INC>, as explained above.
+
+=back
+
+=head2 Escaped colons and relative paths in PATH
+
+On Unix systems, Perl treats any relative paths in the C<PATH> environment
+variable as tainted when starting a new process. Previously, it was
+allowing a backslash to escape a colon (unlike the OS), consequently
+allowing relative paths to be considered safe if the PATH was set to
+something like C</\:.>. The check has been fixed to treat C<"."> as tainted
+in that example.
+
+=head2 New C<-Di> switch is now required for PerlIO debugging output
+
+This is used for debugging of code within PerlIO to avoid recursive
+calls. Previously this output would be sent to the file specified
+by the C<PERLIO_DEBUG> environment variable if perl wasn't running
+setuid and the C<-T> or C<-t> switches hadn't been parsed yet.
+
+If perl performed output at a point where it hadn't yet parsed its
+switches this could result in perl creating or overwriting the file
+named by C<PERLIO_DEBUG> even when the C<-T> switch had been supplied.
+
+Perl now requires the C<-Di> switch to be present before it will produce
+PerlIO debugging
+output. By default this is written to C<stderr>, but can optionally
+be redirected to a file by setting the C<PERLIO_DEBUG> environment
+variable.
+
+If perl is running setuid or the C<-T> switch was supplied,
+C<PERLIO_DEBUG> is ignored and the debugging output is sent to
+C<stderr> as for any other C<-D> switch.
+
+=head1 Incompatible Changes
+
+=head2 Unescaped literal C<"{"> characters in regular expression
+patterns are no longer permissible
+
+You have to now say something like C<"\{"> or C<"[{]"> to specify to
+match a LEFT CURLY BRACKET; otherwise, it is a fatal pattern compilation
+error. This change will allow future extensions to the language.
+
+These have been deprecated since v5.16, with a deprecation message
+raised for some uses starting in v5.22. Unfortunately, the code added
+to raise the message was buggy and failed to warn in some cases where
+it should have. Therefore, enforcement of this ban for these cases is
+deferred until Perl 5.30, but the code has been fixed to raise a
+default-on deprecation message for them in the meantime.
+
+Some uses of literal C<"{"> occur in contexts where we do not foresee
+the meaning ever being anything but the literal, such as the very first
+character in the pattern, or after a C<"|"> meaning alternation. Thus
+
+ qr/{fee|{fie/
+
+matches either of the strings C<{fee> or C<{fie>. To avoid forcing
+unnecessary code changes, these uses do not need to be escaped, and no
+warning is raised about them, and there are no current plans to change this.
+
+But it is always correct to escape C<"{">, and the simple rule to
+remember is to always do so.
+
+See L<Unescaped left brace in regex is illegal here|perldiag/Unescaped left brace in regex is illegal here in regex; marked by S<E<lt>-- HERE> in mE<sol>%sE<sol>>.
+
+=head2 C<scalar(%hash)> return signature changed
+
+The value returned for C<scalar(%hash)> will no longer show information about
+the buckets allocated in the hash. It will simply return the count of used
+keys. It is thus equivalent to C<0+keys(%hash)>.
+
+A form of backward compatibility is provided via
+L<C<Hash::Util::bucket_ratio()>|Hash::Util/bucket_ratio> which provides
+the same behavior as
+C<scalar(%hash)> provided in Perl 5.24 and earlier.
+
+=head2 C<keys> returned from an lvalue subroutine
+
+C<keys> returned from an lvalue subroutine can no longer be assigned
+to in list context.
+
+ sub foo : lvalue { keys(%INC) }
+ (foo) = 3; # death
+ sub bar : lvalue { keys(@_) }
+ (bar) = 3; # also an error
+
+This makes the lvalue sub case consistent with C<(keys %hash) = ...> and
+C<(keys @_) = ...>, which are also errors.
+L<[perl #128187]|https://rt.perl.org/Public/Bug/Display.html?id=128187>
+
+=head2 The C<${^ENCODING}> facility has been removed
+
+The special behaviour associated with assigning a value to this variable
+has been removed. As a consequence, the L<encoding> pragma's default mode
+is no longer supported. If
+you still need to write your source code in encodings other than UTF-8, use a
+source filter such as L<Filter::Encoding> on CPAN or L<encoding>'s C<Filter>
+option.
+
+=head2 C<POSIX::tmpnam()> has been removed
+
+The fundamentally unsafe C<tmpnam()> interface was deprecated in
+Perl 5.22 and has now been removed. In its place, you can use,
+for example, the L<File::Temp> interfaces.
+
+=head2 require ::Foo::Bar is now illegal.
+
+Formerly, C<require ::Foo::Bar> would try to read F</Foo/Bar.pm>. Now any
+bareword require which starts with a double colon dies instead.
+
+=head2 Literal control character variable names are no longer permissible
+
+A variable name may no longer contain a literal control character under
+any circumstances. These previously were allowed in single-character
+names on ASCII platforms, but have been deprecated there since Perl
+5.20. This affects things like C<$I<\cT>>, where I<\cT> is a literal
+control (such as a C<NAK> or C<NEGATIVE ACKNOWLEDGE> character) in the
+source code.
+
+=head2 C<NBSP> is no longer permissible in C<\N{...}>
+
+The name of a character may no longer contain non-breaking spaces. It
+has been deprecated to do so since Perl 5.22.
+
+=head1 Deprecations
+
+=head2 String delimiters that aren't stand-alone graphemes are now deprecated
+
+For Perl to eventually allow string delimiters to be Unicode
+grapheme clusters (which look like a single character, but may be
+a sequence of several ones), we have to stop allowing a single character
+delimiter that isn't a grapheme by itself. These are unlikely to exist
+in actual code, as they would typically display as attached to the
+character in front of them.
+
+=head2 C<\cI<X>> that maps to a printable is no longer deprecated
+
+This means we have no plans to remove this feature. It still raises a
+warning, but only if syntax warnings are enabled. The feature was
+originally intended to be a way to express non-printable characters that
+don't have a mnemonic (C<\t> and C<\n> are mnemonics for two
+non-printable characters, but most non-printables don't have a
+mnemonic.) But the feature can be used to specify a few printable
+characters, though those are more clearly expressed as the printable
+itself. See
+L<http://www.nntp.perl.org/group/perl.perl5.porters/2017/02/msg242944.html>.
+
+=head1 Performance Enhancements
+
+=over 4
+
+=item *
+
+A hash in boolean context is now sometimes faster, I<e.g.>
+
+ if (!%h) { ... }
+
+This was already special-cased, but some cases were missed (such as
+C<grep %$_, @AoH>), and even the ones which weren't have been improved.
+
+=item * New Faster Hash Function on 64 bit builds
+
+We use a different hash function for short and long keys. This should
+improve performance and security, especially for long keys.
+
+=item * readline is faster
+
+Reading from a file line-by-line with C<readline()> or C<< E<lt>E<gt> >> should
+now typically be faster due to a better implementation of the code that
+searches for the next newline character.
+
+=item *
+
+Assigning one reference to another, I<e.g.> C<$ref1 = $ref2> has been
+optimized in some cases.
+
+=item *
+
+Remove some exceptions to creating Copy-on-Write strings. The string
+buffer growth algorithm has been slightly altered so that you're less
+likely to encounter a string which can't be COWed.
+
+=item *
+
+Better optimise array and hash assignment: where an array or hash appears
+in the LHS of a list assignment, such as C<(..., @a) = (...);>, it's
+likely to be considerably faster, especially if it involves emptying the
+array/hash. For example, this code runs about a third faster compared to
+Perl 5.24.0:
+
+ my @a;
+ for my $i (1..10_000_000) {
+ @a = (1,2,3);
+ @a = ();
+ }
+
+=item *
+
+Converting a single-digit string to a number is now substantially faster.
+
+=item *
+
+The C<split> builtin is now slightly faster in many cases: in particular
+for the two specially-handled forms
+
+ my @a = split ...;
+ local @a = split ...;
+
+=item *
+
+The rather slow implementation for the experimental subroutine signatures
+feature has been made much faster; it is now comparable in speed with the
+traditional C<my ($a, $b, @c) = @_>.
+
+=item *
+
+Bareword constant strings are now permitted to take part in constant
+folding. They were originally exempted from constant folding in August 1999,
+during the development of Perl 5.6, to ensure that C<use strict "subs">
+would still apply to bareword constants. That has now been accomplished a
+different way, so barewords, like other constants, now gain the performance
+benefits of constant folding.
+
+This also means that void-context warnings on constant expressions of
+barewords now report the folded constant operand, rather than the operation;
+this matches the behaviour for non-bareword constants.

+Support for compiling perl on Windows using Microsoft Visual Studio 2015

+This version of VC++ includes a completely rewritten C run-time library, some
+of the changes in which mean that work done to resolve a socket
+C<close()> bug in
+perl #120091 and perl #118059 is not workable in its current state with this
+version of VC++. Therefore, we have effectively reverted that bug fix for
+VS2015 onwards on the basis that being able to build with VS2015 onwards is
+more important than keeping the bug fix. We may revisit this in the future to
+attempt to fix the bug again in a way that is compatible with VS2015.
+
+These changes do not affect compilation with GCC or with Visual Studio versions
+up to and including VS2013, I<i.e.>, the bug fix is retained (unchanged) for those
+compilers.
+
+Note that you may experience compatibility problems if you mix a perl built
+with GCC or VS E<lt>= VS2013 with XS modules built with VS2015, or if you mix a
+perl built with VS2015 with XS modules built with GCC or VS E<lt>= VS2013.
+Some incompatibility may arise because of the bug fix that has been reverted
+for VS2015 builds of perl, but there may well be incompatibility anyway because
+of the rewritten CRT in VS2015 (I<e.g.>, see discussion at

+
+The functions L<C<utf8n_to_uvchr>|perlapi/utf8n_to_uvchr> and its
+derivatives have had several changes of behaviour.
+
+Calling them, while passing a string length of 0 is now asserted against
+in DEBUGGING builds, and otherwise, returns the Unicode REPLACEMENT
+CHARACTER. If you have nothing to decode, you shouldn't call the decode
+function.
+
+They now return the Unicode REPLACEMENT CHARACTER if called with UTF-8
+that has the overlong malformation and that malformation is allowed by
+the input parameters. This malformation is where the UTF-8 looks valid
+syntactically, but there is a shorter sequence that yields the same code
+point. This has been forbidden since Unicode version 3.1.
+
+They now accept an input
+flag to allow the overflow malformation. This malformation is when the
+UTF-8 may be syntactically valid, but the code point it represents is
+not capable of being represented in the word length on the platform.
+What "allowed" means, in this case, is that the function doesn't return an
+error, and it advances the parse pointer to beyond the UTF-8 in
+question, but it returns the Unicode REPLACEMENT CHARACTER as the value
+of the code point (since the real value is not representable).
+
+They no longer abandon searching for other malformations when the first
+one is encountered. A call to one of these functions thus can generate
+multiple diagnostics, instead of just one.
+
+=item *
+
+L<C<valid_utf8_to_uvchr()>|perlapi/valid_utf8_to_uvchr> has been added
+to the API (although it was
+present in core earlier). Like C<utf8_to_uvchr_buf()>, but assumes that
+the next character is well-formed. Use with caution.
+
+=item *
+
+A new function, L<C<utf8n_to_uvchr_error>|perlapi/utf8n_to_uvchr_error>,
+has been added for
+use by modules that need to know the details of UTF-8 malformations
+beyond pass/fail. Previously, the only ways to know why a sequence was
+ill-formed was to capture and parse the generated diagnostics or to do
+your own analysis.
+
+=item *
+
+There is now a safer version of utf8_hop(), called
+L<C<utf8_hop_safe()>|perlapi/utf8_hop_safe>.
+Unlike utf8_hop(), utf8_hop_safe() won't navigate before the beginning or
+after the end of the supplied buffer.
+
+=item *
+
+Two new functions, L<C<utf8_hop_forward()>|perlapi/utf8_hop_forward> and
+L<C<utf8_hop_back()>|perlapi/utf8_hop_back> are
+similar to C<utf8_hop_safe()> but are for when you know which direction
+you wish to travel.
+
+=item *
+
+Two new macros which return useful utf8 byte sequences:
+
+L<C<BOM_UTF8>|perlapi/BOM_UTF8>
+
+L<C<REPLACEMENT_CHARACTER_UTF8>|perlapi/REPLACEMENT_CHARACTER_UTF8>
+
+=back

+
+Perl is now built with the C<PERL_OP_PARENT> compiler define enabled by
+default. To disable it, use the C<PERL_NO_OP_PARENT> compiler define.
+This flag alters how the C<op_sibling> field is used in C<OP> structures,
+and has been available optionally since perl 5.22.
+
+See L<perl5220delta/"Internal Changes"> for more details of what this
+build option does.
+
+=item *
+
+Three new ops, C<OP_ARGELEM>, C<OP_ARGDEFELEM>, and C<OP_ARGCHECK> have
+been added. These are intended principally to implement the individual
+elements of a subroutine signature, plus any overall checking required.
+
+=item *
+
+The C<OP_PUSHRE> op has been eliminated and the C<OP_SPLIT> op has been
+changed from class C<LISTOP> to C<PMOP>.
+
+Formerly the first child of a split would be a C<pushre>, which would have the
+C<split>'s regex attached to it. Now the regex is attached directly to the
+C<split> op, and the C<pushre> has been eliminated.
+
+=item *
+
+The L<C<op_class()>|perlapi/op_class> API function has been added. This
+is like the existing
+C<OP_CLASS()> macro, but can more accurately determine what struct an op
+has been allocated as. For example C<OP_CLASS()> might return
+C<OA_BASEOP_OR_UNOP> indicating that ops of this type are usually
+allocated as an C<OP> or C<UNOP>; while C<op_class()> will return
+C<OPclass_BASEOP> or C<OPclass_UNOP> as appropriate.
+
+=item *
+
+All parts of the internals now agree that the C<sassign> op is a C<BINOP>;
+previously it was listed as a C<BASEOP> in F<regen/opcodes>, which meant
+that several parts of the internals had to be special-cased to accommodate
+it. This oddity's original motivation was to handle code like C<$x ||= 1>;
+that is now handled in a simpler way.
+
+=item *
+
+The output format of the L<C<op_dump()>|perlapi/op_dump> function (as
+used by C<perl -Dx>)
+has changed: it now displays an "ASCII-art" tree structure, and shows more
+low-level details about each op, such as its address and class.
+
+=item *
+
+The C<PADOFFSET> type has changed from being unsigned to signed, and
+several pad-related variables such as C<PL_padix> have changed from being
+of type C<I32> to type C<PADOFFSET>.
+
+=item *
+
+The C<DEBUGGING>-mode output for regex compilation and execution has been
+enhanced.
+
+=item *
+
+Several obscure SV flags have been eliminated, sometimes along with the
+macros which manipulate them: C<SVpbm_VALID>, C<SVpbm_TAIL>, C<SvTAIL_on>,
+C<SvTAIL_off>, C<SVrepl_EVAL>, C<SvEVALED>.
+
+=item *
+
+An OP C<op_private> flag has been eliminated: C<OPpRUNTIME>. This used to
+often get set on C<PMOP> ops, but had become meaningless over time.

+Use of a string delimiter whose code point is above 2**31 now works
+correctly on platforms that allow this. Previously, certain characters,
+due to truncation, would be confused with other delimiter characters
+with special meaning (such as C<"?"> in C<m?...?>), resulting

+List assignment in list context where the LHS contained aggregates and

+Previously, C<(($a,$b,@c,$d) = (1))> in list context returned C<($a)>; now
+it returns C<($a,$b,$d)>. C<(($a,$b,$c) = (1))> is unchanged: it still
+returns C<($a,$b,$c)>. This can be seen in the following:
+
+ sub inc { $_++ for @_ }
+ inc(($a,$b,@c,$d) = (10))
+
+Formerly, the values of C<($a,$b,$d)> would be left as C<(11,undef,undef)>;

+
+Jon Portnoy (AVENJ), a prolific Perl author and admired Gentoo community
+member, has passed away on August 10, 2016. He will be remembered and
+missed by all those who he came in contact with, and enriched with his
+intellect, wit, and spirit.
+
+It is with great sadness that we also note Kip Hampton's passing. Probably
+best known as the author of the Perl & XML column on XML.com, he was a
+core contributor to AxKit, an XML server platform that became an Apache
+Foundation project. He was a frequent speaker in the early days at
+OSCON, and most recently at YAPC::NA in Madison. He was frequently on
+irc.perl.org as ubu, generally in the #axkit-dahut community, the
+group responsible for YAPC::NA Asheville in 2011.
+
+Kip and his constant contributions to the community will be greatly
+missed.

In Perl 5.30, delimiters which are unassigned code points, or which
are non-standalone graphemes will be fatal.
+=head3 In XS code, use of various macros dealing with UTF-8.
+
+These macros will require an extra parameter in Perl 5.30:
+C<isALPHANUMERIC_utf8>,
+C<isASCII_utf8>,
+C<isBLANK_utf8>,
+C<isCNTRL_utf8>,
+C<isDIGIT_utf8>,
+C<isIDFIRST_utf8>,
+C<isPSXSPC_utf8>,
+C<isSPACE_utf8>,
+C<isVERTWS_utf8>,
+C<isWORDCHAR_utf8>,

+C<isPUNCT_LC_utf8>,
+C<isSPACE_LC_utf8>,
+C<isUPPER_LC_utf8>,
+C<isWORDCHAR_LC_utf8>,
+C<isXDIGIT_LC_utf8>,
+C<toFOLD_utf8>,
+C<toLOWER_utf8>,
+C<toTITLE_utf8>,
+and
+C<toUPPER_utf8>.
+
+There is now a macro that corresponds to each one of these, simply by
+appending C<_safe> to the name. It takes the extra parameter.
+For example, C<isDIGIT_utf8_safe> corresponds to C<isDIGIT_utf8>, but
+takes the extra parameter, and its use doesn't generate a deprecation
+warning. All are documented in L<perlapi/Character case changing> and
+L<perlapi/Character classification>.
+
+You can change to use these versions at any time, or, if you can live
+with the deprecation messages, wait until 5.30 and add the parameter to
+the existing calls, without changing the names.
