NAME
perl5114delta - what is new for perl v5.11.4
DESCRIPTION
This document describes differences between the 5.11.3
release and the 5.11.4 release.
If you are upgrading from an earlier release such as 5.11.2,
first read perl5113delta, which describes differences
between 5.11.2 and 5.11.3.
Incompatible Changes
Version number formats
Acceptable version number formats have been formalized into
"strict" and "lax" rules. "package NAME VERSION" takes a
strict version number. "use NAME VERSION" takes a lax
version number. "UNIVERSAL::VERSION" and the version object
constructors take lax version numbers. Providing an invalid
version will result in a fatal error.
These formats will be documented fully in the version module
in a subsequent release of Perl 5.11. To a first
approximation, a "strict" version number is a positive
decimal number (integer or decimal-fraction) without
exponentiation or else a dotted-decimal v-string with a
leading 'v' character and at least three components. A
"lax" version number allows v-strings with fewer than three
components or without a leading 'v'. Under "lax" rules,
both decimal and dotted-decimal versions may have a trailing
"alpha" component separated by an underscore character after
a fractional or dotted-decimal component.
The version module adds "version::is_strict" and
"version::is_lax" functions to check a scalar against these
rules.
Core Enhancements
Unicode properties
"\p{XDigit}" now matches the same characters as
"\p{Hex_Digit}". This means that in addition to the
characters it currently matches, "[A-Fa-f0-9]", it will also
match their fullwidth equivalent forms, for example U+FF10:
FULLWIDTH DIGIT ZERO.
Modules and Pragmata
Pragmata Changes
"less"
Upgraded from version 0.02 to 0.03.
This version introduces the "stash_name" method to allow
subclasses of less to pick where in %^H to store their
stash.
perl v5.12.5 Last change: 2012-11-03 1
Perl Programmers Reference Guide PERL5114DELTA(1)
"version"
Upgraded from version 0.77 to 0.81.
This version adds support for "Version number formats"
as described earlier in this document and in its own
documentation.
"warnings"
Upgraded from version 1.08 to 1.09.
This version adds the "illegalproto" warning category.
See also "New or Changed Diagnostics" for this change.
Updated Modules
"Archive::Extract"
Upgraded from version 0.36 to 0.38.
"B::Deparse"
Upgraded from version 0.93 to 0.94.
"Compress::Raw::Bzip2"
Upgraded from version 2.021 to 2.024.
"Compress::Raw::Zlib"
Upgraded from version 2.021 to 2.024.
"CPAN"
Upgraded from version 1.94_5301 to 1.94_54.
"File::Fetch"
Upgraded from version 0.22 to 0.24.
"Module::Build"
Upgraded from version 0.36 to 0.3603.
"Safe"
Upgraded from version 2.20 to 2.21.
Anonymous coderefs created in Safe containers no longer
get bogus arguments passed to them, fixing RT #72068.
Removed Modules and Pragmata
"Devel::DProf::V"
Removed from the Perl core. Prior version was 'undef'.
Changes to Existing Documentation
A significant fraction of the core documentation has been
updated to clarify the behavior of Perl's Unicode handling.
Much of the remaining core documentation has been reviewed
and edited for clarity, consistent use of language, and to
fix the spelling of Tom Christiansen's name.

Configuration improvements
USE_ATTRIBUTES_FOR_PERLIO is now reported in the compile-
time options listed by the "-V" switch.
Platform Specific Changes
VMS The default pipe buffer size on VMS has been updated to
8192 on 64-bit systems.
Selected Bug Fixes
o Tie::Hash::NamedCapture::* shouldn't abort if passed bad
input (RT #71828)
o @_ and $_ no longer leak under threads (RT #34342 and
#41138, also #70602, #70974)
New or Changed Diagnostics
New warning category "illegalproto"
The two warnings :
Illegal character in prototype for %s : %s
Prototype after '%c' for %s : %s
have been moved from the "syntax" top-level warnings
category into a new first-level category,
"illegalproto". These two warnings are currently the
only ones emitted during parsing of an invalid/illegal
prototype, so one can now do
no warnings 'illegalproto';
to suppress only those, but not other syntax-related
warnings. Warnings where prototypes are changed,
ignored, or not met are still in the "prototype"
category as before. (Matt S. Trout)
lvalue attribute ignored after the subroutine has been
defined
This new warning is issued when one attempts to mark a
subroutine as lvalue after it has been defined.
Changed Internals
o Perl_magic_setmglob now knows about globs, fixing RT
#71254.
Known Problems
Perl 5.11.4 is a development release leading up to Perl
5.12.0. Some notable known problems found in 5.11.4 are
listed as dependencies of RT #69710, the Perl 5 version 12
meta-ticket.
Deprecations
The following items are now deprecated.

Perl Programmers Reference Guide PERL5114DELTA(1)
"UNIVERSAL->import()"
The method "UNIVERSAL->import()" is now deprecated.
Attempting to pass import arguments to a "use UNIVERSAL"
statement will result in a deprecation warning. (This is
a less noisy version of the full deprecation warning
added in 5.11.0.)
Acknowledgements
Perl 5.11.4 represents approximately one month of
development since Perl 5.11.3 and contains 17682 lines of
changes across 318 files from 40 authors and committers:

Many of the changes included in this version originated in
the CPAN modules included in Perl's core. We're grateful to
the entire CPAN community for helping Perl to flourish.
Reporting Bugs
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
<http://rt.perl.org/perlbug/>. There may also be
information at <http://www.perl.org/>, the Perl Home Page.
If you believe you have an unreported bug, please run the
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 "perl -V", will be sent off
to perlbug@perl.org to be analyzed by the Perl porting team.
If the bug you are reporting has security implications,
which make it inappropriate to send to a publicly archived
mailing list, then please send it to
perl5-security-report@perl.org. This points to a closed
subscription unarchived mailing list, which includes all the
core committers, who be able to help assess the impact of
issues, figure out a resolution, and help co-ordinate the
release of patches to mitigate or fix the problem across all
platforms on which Perl is supported. Please only use this
address for security issues in the Perl core, not for
modules independently distributed on CPAN.
