Proto Software has released v1.5 of their custom applications builder, which includes a free, full-featured version of the software for personal (non-commercial) use. You can check out a screencast to see what’s new, and if you want to give it a whirl there’s over 20 detailed guides to get you on your feet.

The free version seems like a good move to increase Proto’s userbase as more and more students and hackers become widget and webapp hobbyists in their free time. Congrats to Jeb and Byron on the release!
