Hello!
we have packaged PHP 5.3.0RC3, which you can find here:
http://downloads.php.net/johannes/
Windows binaries are available here:
http://windows.php.net/qa/
This third release candidate focused on bug fixes and stability
improvements and we hope to only require minimal changes ahead
of the next release. Many, but not all, of the new features are
already integrated in the official documentation on php.net.
Please not that we are aware of a few minor issues including that we
still want to fix for the final release. We are aiming for an RC4 next
week followed by the final release in the week after. For most users
there will not be a noticeable change meaning that now is the time
to really do the final testing of PHP 5.3.0 before it gets released
with any unnecessary incompatibilities with your project.
