Firmware 1.6.0 - any issues encountered?

Hey all, I just received my top hat, and going through the user manual it states to use FW 1.5.0 and up.

I made the mistake back then going to 1.5.0 and even tried 1.5.2 and still had issues. I've since reverted back to 1.4.x and printing fine.

Are any of you on 1.6.x? Any issues with the printer and how it's printing? (layers, tool changing, etc)
