Work on R3 is progressing well, with all sorts of new features slated to make the cut!
Many new kernel choices:
-Cooperative-mode (single threaded) for stack-conscious hosts
-Tiny round-robin preemptive scheduler (Pipsqueak kernel) for systems where just the bare minimum of multithreading kernels is needed
-Full C++ kernel port (FunkOS++ kernel), including all features from the normal "C" kernel
New GUI framework (Fooey GUI) with a set of example widgets
Includes a FAT16/32 filesystem driver (read-only, short filenames for now)
New AVR Ports:
-Codevision (with help from A. Shawqy)
-IAR (with help from A. Shawqy)
New buffered UART Driver for AVR
Plus the usual bugfixes to ports and demos.
R3 should be out sometime in March.
