Added new EVENT_CDC_Device_BreakSent() event and CDC_Host_SendBreak() function to the Device and Host CDC Class drivers.

Ensure that the CDC class drivers return 0 if the number of unread bytes is queried and the bank has become empty.

Fixed INTERRUPT_CONTROL_ENDPOINT compile time option preventing other interrupts from occuring while the control endpoint request is being processed, causing possible lockups if a USB interrupt occurs during a transfer.

Fixed Host mode HID class driver not sending the correct report type when HID_Host_SendReportByID() was called and the HID_HOST_BOOT_PROTOCOL_ONLY compile time option is set.

Fixed Set Configuration requests not being stalled until the host has set the device's address.

Fixed possibility of internal signature retrieval being corrupted if an interrupt occurs during a signature byte read (thanks to Andrei Krainev).

Added new ENDPOINT_*_BusSuspended error code to the Endpoint function, so that the stream functions early-abort if the bus is suspended before or during a transfer.

The Audio_Device_IsSampleReceived() and Audio_Device_IsReadyForNextSample() functions are now inline, to reduce overhead.

Use puts_P() and printf_P() instead of the normal variants where possible in the Host mode Class Driver demos.

Oops - relocated USBInterrupt.h header file requires adjusted include paths for the other USB driver header files.

Relocate USBInterrupt.c/.h from the HighLevel USB driver directory to the LowLevel directory as it is hardware-dependent.

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 HID Device Class Driver not allocating a temporary buffer when the host requests a report via the control endpoint and the user has set the PrevReportINBuffer driver configuration element to NULL (thanks to Lars Noschinski).

Clean up incomplete BluetoothHost debugging commands to use GCC extension to avoid NULL parameters when no formatting is required.

Rename FunctionAttributes.h to Attributes.h, as some attributes are applicable to variables also. Add new ATTR_NOINIT attribute for global variables.

Add the beginnings of a SDP implentation to the incomplete BluetoothHost demo.

Add const attribute to the Mass Storage Host driver functions where it was applicable, but missing.

Fixed Set/Clear Feature requests directed to a non-configured endpoint not returning a stall to the host.

Make TeensyHID bootloader use an 8 byte control endpoint to match the official Teensy, just in case Paul decides to authenticate on that attribute in the future.

Removed two-step endpoint/pipe bank clear and switch sequence for smaller, faster endpoint/pipe code.

Added spacing between multiple paragraphs in Doxygen \note sections.

Removed call to the clock prescaler reset function in the Teensy bootloader to save space - the user application is accessed via a watchdog reset anyway, so the prescale reset would only affect the speed of the bootloader itself.

Oops, incorrectly edited the Benito buttons driver file instead of the JM-DB-U2 buttons driver file.

Fix up preprocessor guards in the new board driver files.

Add button support for the BENITO board target.

Remove accidentally duplicated model-specific peripheral driver files.

All Class Driver Host mode demos now correctly set the board LEDs to READY once the enumeration process has completed.

Fixed Still Image Host class driver not resetting the transaction ID when a new session is opened, fixed driver not sending a valid session ID to the device.

Added hardware board driver support for the PJRC Teensy line of USB AVR boards.

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.

Fixed ADC routines failing to read the extended channels (Channels 8 to 13, Internal Temperature Sensor) on the U4 series USB AVR parts.

Fix missing text from the Host Mode States enum documentation.

Fix TWI driver not aborting when faced with no response after attempting to address a device on the bus.

Added a timeout value to the TWI_StartTransmission() function, within which the addressed device must respond.

Fixed TWI_StartTransmission() corrupting the contents of the GPIOR0 register.
