It gives me great pleasure to announce the release of Perl 5.15.0.

This is the first DEVELOPMENT release in the 5.15.x series leading to a
stable release of Perl 5.16.0. You can find a list of high-profile
changes in this release in the file "perldelta.pod" inside the

The release's SHA1 signatures are:

  08fe5e6ada034726991d5806df744206677fb01e  perl-5.15.0.tar.bz2
  75abfe2bd8818aa7a532340221446c36b4a6fb03  perl-5.15.0.tar.gz

We welcome your feedback on this release. If you discover issues with
Perl 5.15.0, please use the 'perlbug' tool included in this distribution
to report them. If Perl 5.15.0 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:

* CORE:: can be used on all keywords without using

* $$ no longer caches PID

* Modules deprecated in 5.14.0 have been removed, including and Devel::Dprof

* Multiple bug fixes to regular expressions and the new character
  classes and flags

* Multiple bug fixes for copy-on-write scalars

* Multiple bug fixes for lvalue subroutines
