So you know about that big scary update for Verizon's Galaxy S 4 that blocks root, patches the bootloader, and haunts your children's dreams. The question is, though, what else does it do? Verizon finally spilled the beans (someone grab a mop and clean this mess up, please), and it's chock-full of stuff. Lots and lots of stuff.

See? Some things were removed, others were added, and there were a slew of enhancements. Also some bug fixes. Unfortunately, that also includes patching your device's bootloader and blocking all known root methods. Ouch.

Fortunately, if you haven't grabbed this one from Verizon's fancy new Software Upgrade Assistant, you're still safe. If, for some reason, you don't mind losing all device freedoms, you can find the full upgrade instructions here.
