Highlights
The C-SPY debugger for Atmel AVR JTAGICE mkII now supports the new Atmel XMEGATM AVR device family.
Support has been added for the Atmel AVR Dragon emulator.

Important information
Support for the AT86RF401 derivative
Support has been added for the AT86RF401 derivative with the restriction that EPROM simulation is not yet implemented for the RF derivatives.

Program corrections
EW20021: The bit REGDIS had the wrong name in the following files: iousb82.h and iousb162.h. This has been corrected.

EW20018: Storing a single bit, through a post increment pointer, resulted in an internal error. This has been corrected.

EW20010: Calling, out of reach, constant function pointers, resulted in a fatal error on the high optimization level. This has been corrected.

EW20009: Reading a single bit, through a post increment pointer, resulted in an internal error. This has been corrected.

EW20005: The register PCICR was missing in the following files: iom32c1.h, iom32m1.h, iom32c1.sfr, and iom32m1.sfr. This has been corrected.

EW19993: The bits BODS, and BODSE had incorrect names in iotiny48.h and iotiny88.h. This has been corrected.

EW19976: The bits HWUPI and VBUSTI had incorrect names in the following files: iousb646.h, iousb647.h, iousb1286.h, and iousb1287.h. This has been corrected.

EW19957: The files supporting ATtiny48, ATtiny88, ATtiny23U, ATtiny43U, and ATmega1284P were missing. This has been corrected.
