Perl 5.13.1 is now available!
Message ID:

  And if anyone shall come to you and say that he knows how to construct
  bridges and that perhaps a time will come when you will wish to avail
  yourself of his science in order to cross over a river, out with him!  Out
  with the engineer!  Rivers will be crossed by wading or swimming them, even
  if half the crusaders drown themselves.  Let the engineer go off and build
  bridges somewhere else, where they are badly wanted.  For those who go in
  quest of the sepulchre, faith is bridge enough.

    -- Miguel de Unamuno, "The Sepulchre of Don Quixote"

It gives me great pleasure to announce the release of Perl 5.13.1.

This is the second DEVELOPMENT release in the 5.13.x series leading to a
stable release of Perl 5.13.0. You can find a list of high-profile changes
in this release in the file "perl5131delta.pod" inside the distribution.

You can (or will shortly be able to) download the 5.13.1 release from:

The release's SHA1 signatures are:

  SHA1: 544bad790bbe8cacddc757dbede4c85263f1b72e  perl-5.13.1.tar.gz
  SHA1: 9ebc45fc9dc9d5fabb73883c7fc68c91b3338695  perl-5.13.1.tar.bz2

This release corresponds to commit 464b2b3dcc in Perl's git repository.
It is tagged as 'v5.13.1'.

We welcome your feedback on this release. If you discover issues
with Perl 5.13.1, please use the 'perlbug' tool included in this
distribution to report them. If Perl 5.13.1 works well for you, please
use the 'perlthanks' tool included with this distribution to tell the
all-volunteer development team how much you appreciate their work.

If you write software in Perl, it is particularly important that you test
your software against development releases. While we strive to maintain
source compatibility with prior stable versions of Perl wherever possible,
it is always possible that a well-intentioned change can have unexpected
consequences. If you spot a change in a development version which breaks
your code, it's much more likely that we will be able to fix it before the
next stable release. If you only test your code against stable releases
of Perl, it may not be possible to undo a backwards-incompatible change
which breaks your code.

Perl 5.13.1 represents thirty days of development since Perl 5.13.0 and
contains 15390 lines of changes across 289 files from 34 authors and

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.

Notable changes in this release:

* localized tied hashes, arrays, and scalars are no longer tied

* "given" now returns the value of the last evaluated expression

* die, warn, and $@ have been greatly simplified to eliminate long-standing
  edge cases and action at a distance

* Class::ISA, Pod::Plainer, and Switch have been removed from the core

Development versions of Perl are released monthly on or about the 20th
of the month by a monthly "release manager". You can expect following
upcoming releases:

 June 20       -    Matt Trout
 July 20       -    David Golden
 August 20     -    Florian Ragwitz
