Perl 5.13.0 is now available

The heat still remained at quite a supportable degree. With an
involuntary shudder, I reflected on what the heat must have been
when the volcano of Sneffels was pouring its smoke, flames, and
streams of boiling lava -- all of which must have come up by the
road we were now following. I could imagine the torrents of hot
seething stone darting on, bubbling up with accompaniments of
smoke, steam, and sulphurous stench!
"Only to think of the consequences," I mused, "if the old
volcano were once more to set to work."
   -- Jules Verne, "A journey to the centre of the earth"

It gives me great pleasure to announce the release of Perl 5.13.0.

This is the first DEVELOPMENT release in the 5.13.x series leading to a
stable release of Perl 5.14.0. You can find a list of high-profile changes
in this release in the file "perl5130delta.pod" inside the distribution.

The release's SHA1 signatures are:

We welcome your feedback on this release. If you discover issues
with Perl 5.13.0, please use the 'perlbug' tool included in this
distribution to report them. If Perl 5.13.0 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.

Notable changes in this release:

* "safe signals" optimization

* Assignment to $0 sets the legacy process name with prctl() on Linux

Perl 5.13.0 represents eight days of development since Perl 5.12.0 and

modules included in Perl's core. We're grateful to the entire CPAN
community for helping Perl to flourish.
