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

Remove incorrect Abstract Call Management class specific descriptor from the CDC demos, bootloaders and projects.

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

Make CDC class bootloader hard-reset the AVR when exited instead of a soft-reset. Reduce size of the TeensyHID bootloader slightly.

Fix the TeensyHID bootloader for the larger USB AVR devices, since Paul uses a different (undocumented) addressing scheme on these devices.

Fixed TeensyHID bootloader so that it works with the official TeensyLoader GUI application with all supported AVR models.

Removed software PDI/TPI emulation from the AVRISP-MKII clone project, as it was very buggy. PDI and TPI must now be implemented via seperate headers instead of the one unified ISP/TPI/PDI header.

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.

Switch back to C based timeout ISR in the AVRISP project - assembly version was failing, and only one or two cycles could be shaved off the compiler generated code.

Change AVRISP project's timeout to be interrupt based again, but make the interrupt itself interruptable and use a seperate assembly file to hand-optimize the ISR code.

Removed the cast to uint16_t on the set baud rate in the USBtoSerial project, so that the higher >1M baud rates can be selected (thanks to Steffan).

Make sure that long reads are aborted early if the connection times out while waiting on more bytes in the AVRISP MKII clone project.

Make sure that the NVM bus/controller busy waits in the AVRISP MKII clone project abort properly if a timeout occurs while waiting for a response.

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.

Make AVRISP-MKII clone project's software PDI/TPI mode more robust by keeping track of timeouts while waiting for a Tx/Rx to finish.

Fix TeensyHID bootloader Doxygen configuration file's CREATE_SUBDIRS options set to true instead of false (thanks to Andrei Krainev).

Added new HCI states to properly initialize the bluetooth dongle and retrieve the local BDADDR.

Factored out Bluetooth state information into a new state structure for easy reference in the user application.

Added new StackInitialized() Bluetooth stack callback function.

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.

Minor documentation improvements.

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.

Removed invalid dfu and flip related targets from the bootloaders - bootloaders can only be replaced with an external programmer.

Document the Bluetooth ACL layer. Remove unneeded parameters from the signalling command processing routines.

Change over the code so that the bluetooth packet data is read in by the stack rather than the user application, to make it more unform for sending/receiving, and so the library can handle incomming fragmentation in the future.

Start Service Discovery Protocol decoding and processing.

Add some more documentation to the half-completed Bluetooth Host demo, fix the OpenChannel() command initialising the channel information structure to the wrong initial state once the CONNECTION REQUEST command has been sent to the remote device.
