Ilia just announced over his blog the availability of the first RC of PHP 5.2.4. Everyone is invited to try it and see how it behaves, then report test to PHP QA team.
This release have been long in the making so the changelog is a bit intimidating, so we definitely need a lot of testing for this release. I would like to ask everyone to give this RC a shot and see how it behaves with their code and hopefully not find any regressions. If you do find any, please let us know.
