Well, there's not any news about the (craptacular) Zend IDE, but they do have the newest Zend.com weekly summary with a few little things this past week - nothing major.
I do also have a new PHP IDE that looks pretty cool. It's called PHPCoder and looks like a pretty cool development environment. And best of all - it's free! So, hop on over and give it a try. And for those of you you like to browse before you buy, here's a screenshot link.
