Ilia Alshanetsky has posted about the release of the latest Release Candidate for the PHP 5.2.x series - PHP 5.2.10RC1.

This is a stabilization release with a whole bunch of bug fixes and no new features, so I hope it'll get released quickly. You can help make it happen by testing your code against this RC and reporting any new bugs and/or regressions you come across.

You can grab the source download here and can find the Windows binary packages on the Windows QA site.
