Changed the parameters and behaviour of the USB_GetDeviceConfigDescriptor() function so that it now performs size checks and data validations internally, to simplify user code.

Renamed parameters of SI_Host_ConfigurePipes() to match other Host mode Class drivers.

Re-enabled building of the Host mode demos ClassDriver directory.

Fixed Device mode HID Class driver not explicitly initializing the ReportSize parameter to zero before calling callback routine, so that ignored callbacks don't cause incorrect data to be sent.

Fixed issue in AVRISP project where the target RESET line was being toggled before it was tristated, causing problems synchronising to some targets (thanks to Mike Alex).

Add check to Pipe_IsEndpointBound() in the Mass Storage Host mode Class driver to ensure that multiple instances of the driver can be used on a single device with multiple Mass Storage interfaces.

Added new "Common" section to the class drivers, to hold all mode-independant definitions for clarity.

Moved SCSI command/sense constants into the Mass Storage Class driver, instead of the user-code.

Added pinout information to the AVRISP project.

Added MS_Host_TestUnitReady() and MS_Host_ReadDeviceCapacity() to the host mode Mass Storage Class driver.

Add SCSICodes.h to the Class Driver Common folder, and automatically include it in both the Host and Device Mass Storage Class drivers. Delete existing version from the ClassDriver MassStorage device demo's /Lib/ folder.

Oops: Really disable building of Projects/Host/ClassDriver directory in the Projects/Host/ makefile.

Add more skeleton functions and definitions to the Mass Storage Host mode Class driver.

Made Endpoint_Write_DWord_* functions echo the structure of the matching Endpoint routines for clarity.

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 Programmer's Notepad project file to reflect new location of AVRISP project.

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 up references to functions in the Endpoint/Pipe documentation.

Fixed invalid data being returned when a GetStatus request is issued in Device mode with an unhandled data recipient.

Fix up Programmers Notepad Project file to show new Projects directory layout. Remove now moved AVRISP project from the Projects directory makefile.

Added new Endpoint_SetEndpointDirection() macro to set the current endpoint direction for bidirectional endpoints.

Renamed internal USB_INT_ENDPOINT_SETUP macro to USB_INT_RXSTPI to fit in with the rest of the interrupt vector macros.

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.

Minor updates to the unfinished SideShow demo for clarity.

Added unfinished MassStorageHost class driver demo.

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.

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.

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.

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.

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.

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.
