If you were a subscriber of Google Earth Pro, you can put your credit card back down as the Mountain View-based search giant has just removed the subscription fee from the software.
Something that once cost $399 per year is now completely free, something you just need to fill out a form to receive. Once you're got the license, you can download the free Pro client here. The difference between the $399 per year version and now? Nothing, and that's great. The non-Pro version has print images capped at 1000x1000 compared to the Pro version at 4800x3200, and a few other limitations.
