Thanks, paola! There seems to be lots of new stuff in the API concerning multitasking. None of the source examples have been updated from the last release, and there isn't any API documentation, so I'm not sure if any of the multitasking stuff is meant to be used in applications, or if it's just for desktop management programs. Still, it's nice to see that they are still actively improving the system and not hiding everything.
The multitasking stuff leads me to believe that this is for use with the latest firmware.
