The PHP development group has released the latest Release Candidate in the PHP 5.6.x series: PHP 5.6.0RC2. A reminder, though, this is not a production release, so only use it in testing.
The PHP development team announces the immediate availability of the second 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.
Several issues were fixed in this release candidate including updates to the core engine, internationalization, the PostgreSQL extension and the PHPDBG debugger functionality. You can find the full list in the NEWS file. You can download this latest release from the PHP QA site or the Windows QA site.
