I've been trying to find out when Preview first added support, such as it is, for fillable PDF forms. I'm looking for which version number and when it was released. I'm new to the Mac and am using Preview 5.0.3 on OS 10.6.5, and although it allows you to interact with form fields and save, it also corrupts the form in many ways. If anyone knows of a resource that shows when the various versions of Preview has been released and the new features with each, I'd greatly appreciate it. Thanks.
