If you, like me, use Zend Studio on Mac OS X, you know there were no official Zend 64–bit PHP debugger for Mac OS X. Some time ago Zend posted a true universal binary (including 64–bit version!) to the Zend Advisory Team for testing. We tested it there and it works perfectly!
Today I happy to say that Zend released this version for public use. Read the announcement made by Roy Ganor about it.
