Zend has released a preview release of their PHP framework:
http://framework.zend.com/
Seems to be alright for a preview release, but I think I'll reserve judgement until it is more mature.
Speaking of mature, did anyone notice that they stole Apple's RSS Icon for use on their site? I pulled both into photoshop and they match up pixel for pixel. I guess they had trouble finding a public domain one, a royalty free one, an otherwise free to use one, or trouble making their own..
