USB_Init() no longer calls sei() to enable global interrupts - this must now be done in the user application once all init code has run.

Fixed compilation error in the AudioInput demos when MICROPHONE_BIASED_TO_HALF_RAIL is defined (thanks to C. Scott Ananian).

Minor documentation cleanups.

Make sure HID class driver uses properly cast pointers when writing to the report buffer.

Change over MIDIToneGenerator to use only a single channel (MIDI channel 1) due to cycle constraints.

Standardized the naming scheme given to configuration descriptor sub-elements in the Device mode demos, bootloaders and projects.

Fix errors in the MouseHostWithParser demo from incorrect use of the HID_ALIGN_DATA() macro.

Don't double-read data from the attached disk in the incomplete StandaloneProgrammer project when in host mode.

New BOARD value option BOARD_NONE (equivelent to not specifying BOARD) which will remove all board hardware drivers which do not adversely affect the code operation (currently only the LEDs driver).

Spell-check code/comments in the Webserver/AVRISP-MKII projects.

Fixed CDC and RNDIS host demos and class drivers - bidirectional endpoints should use two seperate pipes, not one half-duplex pipe.

Fix up the incomplete Webserver project so that it integrates with the uIP stack correctly. Add simple HTTP webserver as a placeholder until FatFS can be integrated.

Begin to look into the RNDIS Host Class Driver, which seems to crash on test hardware after many packets have been received.

Fixed a bug in the incomplete Webserver project, where the packet data was not being written to and read from the correct buffer address.

Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders

Changed incomplete Webserver project over to using the uIP timer library.

Fix MassStorageKeyboard demo USE_INTERNAL_SERIAL check being performed before the required library headers were included, causing a compilation error.

Added notes to the class driver functions indicating which functions require what Device/Host state machine states to function.

Add new TemperatureDataLogger project, a simple USB Mass Storage class Temperature Data Logger using the onboard Dataflash and Temperature sensor.

Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).

Make the StandaloneProgrammer project seamlessly read out drive contents from either an attached FAT formatted drive when in host mode, or the onboard FAT formatted dataflash when in device mode.

The incomplete StandaloneProgrammer project now uses Host and Device Mass storage classes, so that program data can either be loaded onto the device's Dataflash storage, or read off an attached USB memory stick.

The USB target family and allowable USB mode tokens are now public and documented (USB_CAN_BE_*, USB_SERIES_*_AVR).

The SCSI_Request_Sense_Response_t and SCSI_Inquiry_Response_t type defines are now part of the Mass Storage Class driver common defines, rather than being defined in the Host mode Class driver section only.

The USB_MODE_HOST token is now defined even when host mode is not available.

Added missing CDC_Host_CreateBlockingStream() function code to the CDC Host Class driver.

Fixed LowLevel Keyboard demo not saving the issued report only after it has been written to the endpoint.

Added support for multiple keyboard keycodes in a single report to the LowLevel and ClassDriver Keyboard demos.

Add new (incomplete) StandaloneProgrammer project, using the ELM Petite FAT library to read files stored on the board's dataflash by the host.

Finished preliminary AVRISP project - all V2 protocol commands now work correctly for basic operations.

Fixed AVRISP V2 Protocol handler for the READ_FLASH_ISP and READ_EEPROM_ISP handler - can now correctly read back device data. Programming command handler is still broken, although first page is written correctly to FLASH in paged write mode.

Updated Benito project -- added hardware interrupt and software buffering for serial data reception to prevent missed characters, condensed pulse generation counters into a struct for clarity.

Added check to CDC_Device_BytesReceived() to ensure 0 is returned when device is not enumerated to a host.

Move AVRISP project's V2Protocol_DelayMS() function to be static inline, as it is now very minimal. Added extra project doxygen documentation.

Fix endianness of LOAD_ADDRESS command data, add correct PROGRAM_FLASH_ISP/PROGRAM_EEPROM_ISP polling and endpoint bank clearing, add hardware delays/timeouts to the V2 Protocol handler in the AVRISP project.

More additions to the PROGRAM_FLASH_ISP and PROGRAM_EEPROM_ISP commands, although neither work correctly yet.

Added dummy RESET_PROTECTIONS handler to prevent the Atmel driver from crashing when the command returns an UNKNOWN_COMMAND error code.

Added PROGRAM_FLASH_ISP and PROGRAM_EEPROM_ISP handler code to the V2 Protocol handler in the AVRISP project, programming complete checks not yet complete.

Fix to V2 Protocol for Fuse/Sig/Lock byte read -- off by one error on the array when writing back the response from the device.

FLASH/EEPROM reading and writing currently broken and unfinished, respectively.

Added V2 protocol handlers for the READ and WRITE memory commands in the AVRISP project. Finished READ command handler, skeleton WRITE handler implemented.

Added Load Extended Command functionality to the LOAD ADDRESS V2 Protocol command handler for devices with more than 64KB of memory.

Fixed AVRISP programmer demo -- can now connect to a target and read/write Sig/Lock/Fuse/OSCCAL bytes successfully.

Changed SPI_Init() to allow for the clock polarity and data sample modes to be set.

Changed Dataflash_Init() to no longer call SPI_Init() automatically.
