I just upgraded my copy of Zend Studio for IBM i from 7.0.2 to 7.2.1. Big improvement!
My use case: I typically use Zend Studio’s “Remote Server” facility to connect to the IBM i over FTP. With 7.2.1, FTP-based files now open and save much faster than before. In addition, the FTP connection no longer randomly disconnects the way it used to.
I recommend upgrading to 7.2.1, especially for anyone using FTP. It provides a smooth, hassle-free user experience.

Note: this product is still free to users of IBM i, a nice benefit of Zend’s relationship with IBM.
