Added ATTR_NON_NULL_PTR_ARG() attributes to the class drivers to improve user code reliability by disallowing explicit NULL pointers as pointer parameters in function calls where the parameter must not be NULL.
Disabled building of the Demos/Host/ClassDriver directory until Host Mode Class drivers are complete to prevent build errors in the meantime.
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.
SetIdle requests to the HID device driver with a 0 idle period (send changes only) now only affect the requested HID interface within the device, not all HID interfaces.
Apply correct fix to the HID report parser for PUSH items - current HID item attribute stack was being copied in the wrong direction.
Fixed HID report parser not resetting the FEATURE item count when a REPORT ID item is encountered.
Adjustments to the CDC and MIDI device class drivers to use sizeof() on the actual variable being transmitted or received rather than its datatype to reduce possible mistakes.
Further work on the new CDC and HID host mode class drivers.
Reset changelog et. al. to reset development information for the new version currently under development.
Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.
Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
Make all audio device Class Driver functions require a reference to the Audio class instance, so that the endpoint size can be checked (and to standardize the APIs).
Make LEDs more responsive in the AudioOutput device demos.
Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.
Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.
Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.
Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.
Fix Keyboard and Mouse demos, Idle period is now multiplied by 4 as the period is read into and sent out of the device to ensure it is always stored as a multiple of 1ms. Fixes Keyboard demo using an initial Idle period of 2s rather than 500ms (thanks to Brian Dickman).
Move out the internal device serial descriptor reading routine into a seperate static function, rather than being part of USB_Device_GetDescriptor.
Added parameter directions to function parameter documentation.
Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
Split out common defines/types from class drivers into a seperate common class driver directory.
Make central USB Class driver dispatch headers, used for both device and host modes.
Redocumented all device demos, now that they have changed over to the new USB class drivers.
Added C linkage to class drivers for C++ support.
Added prefixes to most of the class driver constants to prevent name clashes.
Removed scheduler and memory allocation libraries.
Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).
Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.
