+perldelta - what is new for perl v5.17.4
=head1 DESCRIPTION
-This document describes differences between the 5.17.2 release and the 5.17.3
+This document describes differences between the 5.17.3 release and the 5.17.4
release.
-If you are upgrading from an earlier release such as 5.17.1, first read
-L<perl5172delta>, which describes differences between 5.17.1 and 5.17.2.
-
-=head1 Core Enhancements
-
-=head2 Computed Labels
-
-The loop controls C<next>, C<last> and C<redo>, and the special C<dump>
-operator, now allow arbitrary expressions to be used to compute labels at run
-time. Previously, any argument that was not a constant was treated as the
-empty string.
-
-=head1 Incompatible Changes
-
-=head2 C<$ENV{foo}=undef> deletes value from environ, like C<delete $ENV{foo}>
-
-This facilitates use of C<local()> with C<%ENV> entries. In previous versions
-of Perl, C<undef> was converted to the empty string.
-
-=head2 Defined values stored in environment are forced to byte strings
-
-A value stored in an environment variable has always been stringified. In this
-release, it is converted to be only a byte string. First, it is forced to be a
-only a string. Then if the string is utf8 and the equivalent of
-C<utf8::downgrade()> works, that result is used; otherwise, the equivalent of
-C<utf8::encode()> is used, and a warning is issued about wide characters
-(L</Diagnostics>).
-
-=head2 C<given> now aliases the global C<$_>
-
-Instead of assigning to an implicit lexical C<$_>, C<given> now makes the
-global C<$_> an alias for its argument, just like C<foreach>. However, it
-still uses lexical C<$_> if there is lexical C<$_> in scope (again, just like
-C<foreach>) [perl #114020].

-=head1 Modules and Pragmata
-
-=head2 Updated Modules and Pragmata
-
-=over 4
-
-=item *
-
-L<B> has been upgraded from version 1.36 to 1.37. All C<CVf_*> and C<GVf_*>
-and more SV-related flag values are now provided as constants in the C<B::>
-namespace and available for export. The default export list has not changed.
-
-=item *
-
-L<B::Concise> has been upgraded from version 0.91 to 0.92. The C<-nobanner>
-option has been fixed, and C<format>s can now be dumped. When passed a sub
-name to dump, it will check also to see whether it is the name of a format. If
-a sub and a format share the same name, it will dump both.
-
-=item *
-
-L<B::Debug> has been upgraded from version 1.17 to 1.18. This adds support
-(experimentally) for C<B::PADLIST>, which will be added in Perl 5.17.4.
-
-=item *
-
-L<B::Deparse> has been upgraded from version 1.15 to 1.16. It now deparses
-loop controls with the correct precedence, and multiple statements in a
-C<format> line are also now deparsed correctly.
-
-=item *
-
-L<CGI> has been upgraded from version 3.59 to 3.60. Unrecognized HTML escape
-sequences are now handled better, problematic trailing newlines are no longer
-inserted after E<lt>formE<gt> tags by C<startform()> or C<start_form()>, and
-bogus "Insecure Dependency" warnings appearing with some versions of perl are
-now worked around.
-
-=item *
-
-L<Compress::Raw::Bzip2> has been upgraded from version 2.05201 to 2.055. The
-misuse of Perl's "magic" API has been fixed.
-

-
-L<Compress::Raw::Zlib> has been upgraded from version 2.05401 to 2.056. The

+L<perl5173delta>, which describes differences between 5.17.2 and 5.17.3.
-L<Compress::Zlib> has been upgraded from version 2.052 to 2.055. C<compress()>,
-C<uncompress()>, C<memGzip()> and C<memGunzip()> have been speeded up by making
-parameter validation more efficient.
+=head1 Notice
-=item *
+XXX Any important notices here
-L<Data::Dumper> has been upgraded from version 2.135_06 to 2.135_07. It has
-been optimized to only build a seen-scalar hash as necessary, thereby speeding
-up serialization drastically.
+=head1 Core Enhancements
-=item *
+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.
-L<Devel::Peek> has been upgraded from version 1.08 to 1.09. The only change
-has been to the test script, to account for changes to some flags in perl's
-internals.
+[ List each enhancement as a =head2 entry ]
-=item *
+=head1 Security
-L<Encode> has been upgraded from version 2.44 to 2.47. The Mac alias x-mac-ce
-has been added, and various bugs have been fixed in Encode::Unicode,
-Encode::UTF7 and Encode::GSM0338.
+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.
-=item *
+[ List each security issue as a =head2 entry ]
-L<Module::Build> has been upgraded from version 0.40 to 0.4003. A minor bug
-fix allows markup to be used around the leading "Name" in a POD "abstract"
-line, and some documentation improvements have been made.
+=head1 Incompatible Changes
-=item *
+XXX For a release on a stable branch, this section aspires to be:
-L<Module::CoreList> has been upgraded from version 2.69 to 2.71. Version
-information is now stored as a delta, which greatly reduces the size of the
-F<CoreList.pm> file.
+ 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.
-=item *
+[ List each incompatible change as a =head2 entry ]
-L<Module::Load::Conditional> has been upgraded from version 0.50 to 0.54.
-Various enhancements include the new use of Module::Metadata.
+=head1 Deprecations
-=item *
+XXX Any deprecated features, syntax, modules etc. should be listed here. In
+particular, deprecated modules should be listed here even if they are listed as
+an updated module in the L</Modules and Pragmata> section.
-L<Module::Metadata> has been upgraded from version 1.000009 to 1.000011. The
-creation of a Module::Metadata object for a typical module file has been sped
-up by about 40%, and some spurious warnings about C<$VERSION>s have been
-suppressed.
+[ List each deprecation as a =head2 entry ]
-=item *
+=head1 Performance Enhancements
-L<Module::Pluggable> has been upgraded from version 4.0 to 4.3. Amongst other
-changes, triggers are now allowed on events, which gives a powerful way to
-modify behaviour.
+XXX Changes which enhance performance without changing behaviour go here.
+There may well be none in a stable release.
-=item *
+[ List each enhancement as a =item entry ]
-L<perlfaq> has been upgraded from version 5.0150040 to 5.0150041. This
-contains a couple of minor corrections and lists one new editor.
+=over 4
=item *
-L<Pod::Simple> has been upgraded from version 3.20 to 3.23. Numerous
-improvements have been made, mostly to Pod::Simple::XHTML, which also has a
-compatibility change: the C<codes_in_verbatim> option is now disabled by
-default. See F<cpan/Pod-Simple/ChangeLog> for the full details.
+XXX
-=item *
+=back
-L<re> has been upgraded from version 0.21 to 0.22. Single character [class]es
-like C</[s]/> or C</[s]/i> are now optimized as if they did not have the
-brackets, i.e. C</s/> or C</s/i>.
+=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.
-L<Socket> has been upgraded from version 2.002 to 2.004. Constants and
-functions required for IP multicast source group membership have been added.
+[ Within each section, list entries as a =item entry ]
-=item *
+=head2 New Modules and Pragmata
-L<Storable> has been upgraded from version 2.37 to 2.38. It can now freeze and
-thaw vstrings correctly. This causes a slight incompatible change in the
-storage format, so the format version has increased to 2.9.
+=over 4
=item *
-L<Sys::Syslog> has been upgraded from version 0.29 to 0.31. This contains
-several bug fixes relating to C<getservbyname()>, C<setlogsock()>and log levels
-in C<syslog()>, together with fixes for Windows, Haiku-OS and GNU/kFreeBSD.
-See F<cpan/Sys-Syslog/Changes> for the full details.

-L<Term::ReadLine> has been upgraded from version 1.09 to 1.10. This fixes the
-use of the B<cpan> and B<cpanp> shells on Windows in the event that the current
-drive happens to contain a F<\dev\tty> file.
+=back
-=item *
+=head2 Updated Modules and Pragmata
-L<Text::Tabs> and L<Text::Wrap> have been upgraded from version 2009.0305 to
-2012.0818. Support for Unicode combining characters has been added to them
-both.
+=over 4
=item *
-L<Time::Local> has been upgraded from version 1.2000 to 1.2300. Seconds values
-greater than 59 but less than 60 no longer cause C<timegm()> and C<timelocal()>
-to croak.
+L<XXX> has been upgraded from version A.xx to B.yy.
-=item *

-L<Unicode::UCD> has been upgraded from version 0.44 to 0.45. This has been
-modified slightly for reasons of perl internal use only.
+=head2 Removed Modules and Pragmata

-Format parsing no longer gets confused by braces, semicolons and low-precedence
-operators. It used to be possible to use braces as format delimiters (instead
-of C<=> and C<.>), but only sometimes. Semicolons and low-precedence operators
-in format argument lines no longer confuse the parser into ignoring the line's
-return value. In format argument lines, braces can now be used for anonymous
-hashes, instead of being treated always as C<do> blocks.

+=head1 Internal Changes
-Under debugging builds, the B<-DA> command line option started crashing in Perl

-A potential deadlock scenario involving the premature termination of a pseudo-
-forked child in a Windows build with ithreads enabled has been fixed. This
-resolves the common problem of the F<t/op/fork.t> test hanging on Windows [perl
-#88840].

+=head1 Selected Bug Fixes
-The code which generates errors from C<require()> could potentially read one or
-two bytes before the start of the filename for filenames less than three bytes
-long and ending C</\.p?\z/>. This has now been fixed. Note that it could
-never have happened with module names given to C<use()> or C<require()> anyway.
+XXX Important bug fixes in the core language are summarized here. Bug fixes in
+files in F<ext/> and F<lib/> are best summarized in L</Modules and Pragmata>.
-=item *
+[ List each fix as a =item entry ]
-The handling of pathnames of modules given to C<require()> has been made
-thread-safe on VMS.
+=over 4
=item *
-The C<re_compile()> API function, the entry point for perl's regex compiler,
-was accidentally changed in Perl 5.17.1 to operate on the current engine. This
-has now been restored to its former core-engine-specific state [perl #114302].
+XXX
-=item *
+=back
-Perl 5.17.1 introduced a memory leak into the re-use of run-time regexes where
-the pattern hasn't changed (i.e. C</$unchanging/>). This has now been fixed.
+=head1 Known Problems
-=item *
+XXX Descriptions of platform agnostic bugs we know we can't fix go here. Any
+tests that had to be C<TODO>ed for the release would be noted here. Unfixed
+platform specific bugs also go here.
-A bug in the compilation of a C</(?{})/> expression which affected the TryCatch
-test suite has been fixed [perl #114242].

-=item *
+[ List each fix as a =item entry ]
-Formats no longer leak. They started leaking in Perl 5.17.2.

-Pod can now be nested in code inside a quoted construct outside of a string
-eval. This used to work only within string evals [perl #114040].
