NAME
perl5111delta - what is new for perl v5.11.1
DESCRIPTION
This document describes differences between the 5.11.0
release and the 5.11.1 release.
Incompatible Changes
o The boolkeys op moved to the group of hash ops. This
breaks binary compatibility.
o "\s" "\w" and "\d" once again have the semantics they
had in Perl 5.8.x.
Core Enhancements
Add "package NAME VERSION" syntax
This new syntax allows a module author to set the $VERSION
of a namespace when the namespace is declared with
'package'. It eliminates the need for "our $VERSION = ..."
and similar constructs. E.g.
package Foo::Bar 1.23;
# $Foo::Bar::VERSION == 1.23
There are several advantages to this:
o $VERSION is parsed in exactly the same way as "use NAME
VERSION"
o $VERSION is set at compile time
o Eliminates "$VERSION = ..." and "eval $VERSION" clutter
o As it requires VERSION to be a numeric literal or
v-string literal, it can be statically parsed by
toolchain modules without "eval" the way
MM->parse_version does for "$VERSION = ..."
o Alpha versions with underscores do not need to be
quoted; static parsing will preserve the underscore, but
during compilation, Perl will remove underscores as it
does for all numeric literals
It does not break old code with only "package NAME", but
code that uses "package NAME VERSION" will need to be
restricted to perl 5.11.X or newer This is analogous to
the change to "open" from two-args to three-args. Users
requiring the latest Perl will benefit, and perhaps N
years from now it will become standard practice when
Perl 5.12 is targeted the way that 5.6 is today.

New Documentation
o perlpolicy extends the "Social contract about
contributed modules" into the beginnings of a document
on Perl porting policies.
Changes to Existing Documentation
Documentation for $1 in perlvar.pod clarified
Performance Enhancements
"if (%foo)" has been optimized to be faster than "if (keys
%foo)"
Platform Specific Notes
Darwin (Mac OS X)
o Skip testing the be_BY.CP1131 locale on Darwin 10
(Mac OS X 10.6), as it's still buggy.
o Correct infelicities in the regexp used to identify
buggy locales on Darwin 8 and 9 (Mac OS X 10.4 and
10.5, respectively).
DragonFly BSD
o Fix thread library selection [perl #69686]

Win32
o Initial support for mingw64 is now available
o Various bits of Perl's build infrastructure are no
longer converted to win32 line endings at release
time. If this hurts you, please speak up.
Selected Bug Fixes
o Perl now properly returns a syntax error instead of
segfaulting if "each", "keys" or "values" is used
without an argument
o "tell()" now fails properly if called without an
argument and when no previous file was read
"tell()" now returns "-1", and sets errno to "EBADF",
thus restoring the 5.8.x behaviour
o overload no longer implicitly unsets fallback on
repeated 'use overload' lines
o POSIX::strftime() can now handle Unicode characters in
the format string.
o The Windows select() implementation now supports all
empty "fd_set"s more correctly.
New or Changed Diagnostics
o The 'syntax' category was removed from 5 warnings that
should only be in 'deprecated'.
o Three fatal pack/unpack error messages have been
normalized to "panic: %s"
o "Unicode character is illegal" has been rephrased to be
more accurate
It now reads "Unicode non-character is illegal in
interchange" and the perldiag documentation has been
expanded a bit.
o Perl now defaults to issuing a warning if a deprecated
language feature is used.
To disable this feature in a given lexical scope, you
should use "no warnings 'deprecated';" For information
about which language features are deprecated and
explanations of various deprecation warnings, please see
perldiag
Testing
o Significant cleanups to core tests to ensure that
perl v5.12.5 Last change: 2012-11-03 3
Perl Programmers Reference Guide PERL5111DELTA(1)
language and interpreter features are not used before
they're tested.
o "make test_porting" now runs a number of important pre-
commit checks which might be of use to anyone working on
the Perl core.
o t/porting/podcheck.t automatically checks the well-
formedness of POD found in all .pl, .pm and .pod files
in the MANIFEST, other than in dual-lifed modules which
are primarily maintained outside the Perl core.
o t/porting/manifest.t now tests that all files listed in
MANIFEST are present.
Known Problems
Untriaged test crashes on Windows 2000
Several porters have reported mysterious crashes when
Perl's entire test suite is run after a build on certain
Windows 2000 systems. When run by hand, the individual
tests reportedly work fine.
Known test failures on VMS
Perl 5.11.1 fails a small set of core and CPAN tests as
of this release. With luck, that'll be sorted out for

Acknowledgements

since Perl 5.11.0 contains 22,000 lines of changes across
396 files from 26 authors and committers:
Abigail, Alex Vandiver, brian d foy, Chris Williams, Craig
A. Berry, David Fifield, David Golden, demerphq, Eric Brine,
Geoffrey T. Dairiki, George Greer, H.Merijn Brand, Jan

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
perl v5.12.5 Last change: 2012-11-03 4

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 analysed 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.
