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.

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.

Moved out the handling of V2 Protocol parameters to a seperate set of files. Added parameter privellages, so that an error can be returned to the host when trying to perform a get/set value action on a parameter without the correct privellages.

Fix USBtoSerial device demos -- ensure the UDR1 register contents is read in under all circumstances which fire the ISR, so that the receive complete interrupt is cleared correctly to prevent freezes.

Added new EVENT_USB_Device_StartOfFrame() event, controlled by the new USB_Device_EnableSOFEvents() and USB_Device_DisableSOFEvents() macros to give bus-synchronised millisecond interrupts when in USB device mode.

Adjust endpoint polling intervals for HID demos, to make them compliant with the 10ms minimum polling period for Low Speed devices.

Minor updates to the unfinished SideShow demo for clarity.

Added unfinished MassStorageHost class driver demo.

Minor documentation fixes.

Remove stray state variable from the CDC host class driver.

Fixed swapped paremeters in the HID state memory copy call while processing a HID PUSH item in the HID report parser.

Fixed memory corruption HID report parser when too many COLLECTION or PUSH items were processed.

Make RNDIS device class driver include the CDC device class driver header, so that it can inherrit the required CDC functional descriptor macro.

Make HID host class driver include the HID report parser.

Fix issue in CDC device class driver where received data the size of the data endpoint could lock up the driver.

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.

Cleanups to RNDIS device demos. Fix issue in RNDIS demos where the memory would become corrupted due to an incorrect bounds check when iterating over the port state table, causing random resets.

Revert change to Template_Endpoint_Control_R.c, which broke control stream reads.

Remove uneeded ADC.h include in the class driver AudioOutput demo.

Make Benito ping-pong LED code more explicit, using masks of the TX and RX LED masks for ping-pong toggle rather than the ambiguous LED "Busy" mask.

Fix incorrect event name in MassStorageHost.c.

Simplify CDC device demos, by directly assigning the string to transmit to the pointer, rather than using an intermediatary table to hold all the possible transmit strings.

Make Endpoint control transfers more reliable; early-abort when an incomplete packet is sent from the host (indicating end of transfer), add check for control reads to ensure that no more than wLength bytes are read from the interface.

Condense sequential printf_P/puts_P calls to single printf_P calls for size and clarity.

Fixed issue in USBtoSerial demos where the USART Rx line was not having its pullup enabled at startup, leading to noise being received from the Rx pin when left floating.

Removed unused relative Common.h header include from the DriverStubs board stub drivers.

Fixed Benito programmer, use the correct LED functions where needed to ensure correct status display at all times.

Make Control Endpoint stream transfers more reliable by adding in early aborts for unexpected new SETUP tokens, or unexpected status stage during control stream writes.

Fix corruption in Device RNDIS demos TCP stack when too many connections attempted simultaneously, freezing the device when a page was re-fetched before the first connection was closed.

Fix incorrect model compatibility information in the Host LowLevel demo overview text files.

Changed over manual loops waiting for endpoints to be ready to use the library Endpoint_WaitUntilReady() function for robustness. Fixes issues with terminated transfers on the host locking up USB devices.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

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.

Better fix for LowLevel CDC demo issue where sending data before the line encoding is set will cause a failure of the host to open the port. Added fix to the DualCDC and USBtoSerial LowLevel demos.

Fix issue with CDC device demos causing broken communications when the device tries to send data before the host has set the line encoding.

Rename TOTAL_NUM_CONFIGURATIONS to FIXED_NUM_CONFIGURATIONS, to match the existing FIXED_CONTROL_ENDPOINT_SIZE compile time option. Add FIXED_NUM_CONFIGURATIONS to the descriptors of each project using the option.

Make both LowLevel and ClassDriver AudioOutput demos always output to board LEDs, regardless of output mode (removed AUDIO_OUT_LEDS compile time option from the demo). This allows for positive feedback to the user of audio activity regardless of output mode.

Fixed the ClassDriver GenericHID demo so that it echoes back reports as indicated in the demo overview.

Fix demos based on the device mode HID class driver, as well as the driver itself. Changed HID device class driver to require the user to give a buffer and size to hold the previously generated report, for comparison purposes, and altered the prototype of the CALLBACK_HID_Device_CreateHIDReport() function so that reports can be sent to the host even if there are no apparent changes (useful for relative movements in mice, etc.).

Add new HID_Device_MillisecondElapsed() function to the HID device Class driver, to move the burden of managing the Idle period of each instance to the library and not the user application.

Fix to HID device mode Class driver, so that new reports are compared against the old, and updated reports made within the idle period are sent immediately to the host.

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.

Set all CDC and MassStorage device mode demos (LowLevel and ClassDriver) to use the USE_INTERNAL_SERIAL feature, add compile time warnings for devices which do not have an internal serial.

Fix incorrect HWB button mask in the STK526 Buttons driver.

Fix redefinition warning when USB_DEVICE_ONLY is set on an AVR which does not support USB host mode.

Fixed report data alignment issues in the MouseHostWithParser demo when X and Y movement data size is not a multiple of 8 bits.

Fixed HID Report Descriptor Parser not correctly resetting internal states when a REPORT ID element is encountered.

Change project makefiles so that the current target settings and not just the board selection is printed during the build process.

Fix warning in AudioOutput demos when AUDIO_OUT_STEREO output mode is selected.

Make LowLevel AudioOutput demo work in the same way as the ClassDriver AudioOutput demo for LEDs output.
