Is there some decent information available which WordPress versions do not support PHP 5.3? I mean the more recent ones like 2.9 / 3.0 / 3.1?
I'm only concerned about the Wordpress core codebase, not plugins. I've run WP for most of the time on PHP 5.3 now. But some servers are still on PHP 5.2 and some hosters are concerned if an upgrade might break something, so I try to gather some feedback from a larger community.
The graphical wp.org stats do not differ between WP and PHP versions to each other, this would be some good source as well.
Thanks for your help!
