Well, according to the fine folks over on PHP.net, the latest version of PHP, PHP 4.3.0pre1 has been released. Keep in mind that this is not a stable distribution, but is close to a full release.

PHP 4.3.0 incorporates a very large number of changes, new features, and bugfixes and thus requires extensive testing. This preliminary release is meant to kick-start this testing while the fixes are still being performed. Please join in and help us make this a high-quality release. You can use the build tracker at http://qa.php.net/buildtest-submit.php to report the your results.

I know lots of people that have been waiting for PHP 4.3.0 for a long time, and I know there's a few features in there that I can't wait for (like using SSL in fsockopens..) What all are you guys looking forward to?
