The PHP development team has officially released the next Release Candidate in the PHP 5.6.x series today - PHP 5.6.0RC3. Reminder, this is not a production (stable) release so do not use it in live applications.
The PHP development team announces the immediate availability of the third release candidate of PHP 5.6. As we entered the feature freeze with beta1, this is a bugfix-only release. All users of PHP are encouraged to test this version carefully, and report any bugs in the bug tracking system.
You can download it from the usual QA-related places: qa.php.net for the source and windows.php.net for the Windows binaries. The release timeline is expecting the next Candidate to be posted on August 14th.
