USB_HostRequest renamed to USB_ControlRequest, entire control request header is now read into USB_ControlRequest in Device mode rather than having the library pass only partially read header data to the application.

The USB_UnhandledControlPacket event has had its parameters removed, in favour of accessing the new USB_ControlRequest structure.

The Endpoint control stream functions now correctly send a ZLP to the host when less data than requested is sent.

Removed specialized Endpoint_ClearControl* and Pipe_ClearControl* macros in favour of the standard Endpoint_Clear* and Pipe_Clear* macros (Atmel have confirmed no effect from setting FIFOCON on control endpoints).

Changed over all deprecated GCC structure tag initializers to the standardized C99 format (thanks to Mike Alexander).

Fixed incorrect HID interface class and subclass values in the Mouse and KeyboardMouse demos (thanks to Brian Dickman).

Capitolised the "Descriptor_Search" and "Descriptor_Search_Comp" prefixes of the values in the DSearch_Return_ErrorCodes_t and DSearch_Comp_Return_ErrorCodes_t enums.

Minor documentation improvements.

Removed "Host_" section of the function names in ConfigDescriptor.h, as most of the routines can now be used in device mode on the device descriptor.

Renamed functions in the HID parser to have a "USB_" prefix and the acronym "HID" in the name.

Further module-level documentation updates.

More documentation changes for better module-level documentation rather than file-level documentation.

Fixed CDC and USBtoSerial demos freezing where buffers were full while still transmitting or receiving (thanks to Peter Hand).

Renamed Serial_Stream driver to SerialStream to remain consistent with the rest of the library's naming scheme for files.

Fixed GenericHIDHost demo report write routine incorrect for control type requests (thanks to Andrei Krainev).

Removed Endpoint_ClearCurrentBank() and Pipe_ClearCurrentBank() in favour of new Endpoint_ClearIN(), Endpoint_ClearOUT(), Endpoint_ClearControlIN(), Endpoint_ClearControlOUT(), Pipe_ClearIN(), Pipe_ClearOUT(), Pipe_ClearControlIN() and Pipe_ClearControlOUT() macros (done to allow for the detection of packets of zero length).

Renamed *_ReadWriteAllowed() macros to *_IsReadWriteAllowed() to remain consistent with the rest of the LUFA API.

Endpoint_IsSetupReceived() macro has been renamed to Endpoint_IsSETUPReceived(), Endpoint_ClearSetupReceived() macro has been renamed to Endpoint_ClearControlSETUP(), the Pipe_IsSetupSent() macro has been renamed to Pipe_IsSETUPSent() and the Pipe_ClearSetupSent() macro is no longer applicable and should be removed - changes made to compliment the new endpoint and pipe bank management API.

Updated all demos, bootloaders and projects to use the new endpoint and pipe management APIs (thanks to Roman Thiel).

Updated library doxygen documentation, added groups, changed documentation macro functions to real functions for clarity.

Removed old endpoint and pipe aliased read/write/discard routines which did not have an explicit endian specifier for clarity.

Removed the ButtLoadTag.h header file, as no one used for its intended purpose anyway.

Fixed minor issue with the RNDISEthernet demo DHCP protocol decoder routine using incorrectly named variables (thanks to Jonathan Oakley).

Fixed GenericHIDHost demo report write routine incorrect for control type requests (thanks to Andrei).

Corrected AudioInput and AudioOutput demos, to fix endpoint underflows due to rounding in the sample reload timer.

The USB_Host_SendControlRequest() function no longer automatically selects the Control pipe (pipe 0), so that other control type pipes can be used with the function.

The USB Host management task now saves and restores the currently selected pipe before and after the task completes.

Adjusted sample CTC timer calculations in the AudioOutput and AudioInput demos to account for situations where the division results in a value with no remainder, requiring one to be subtracted from the result (thanks to Robin Theunis).

Fixed RNDISEthenet demo checking the incorrect message field for packet size constraints (thanks to Jonathan).

Fixed WriteNextReport code in the GenericHIDHost demo using incorrect parameter types and not selecting the correct endpoint.

Fixed GenericHID demo not starting USB and HID management tasks when not using interrupt driven modes (thanks to Carl Kjeldsen).

Added support to the CDCHost demo for devices with mutiple CDC interfaces which are not the correct ACM type preceeding the desired ACM CDC interface.

Added preprocessor checks and documentation to the bootloaders giving information about missing SIGNATURE_x defines due to outdated avr-libc versions.

Removed all binary constants and replaced with decimal or hexadecimal constants so that unpatched GCC compilers can still build the code without having to be itself patched and recompiled first.

Move StdRequestType.h, StreamCallbacks.h, USBMode.h from the LowLevel USB driver directory to the HighLevel USB driver directory, where they are more suited.

Add call to MassStore_WaitForDataReceived() in MassStore_GetReturnedStatus() to ensure that the CSW has been received in the extended MSC timeout period before continuing, to prevent long processing delays from causing the MassStore_GetReturnedStatus() to early-abort.

All comments in the library, bootloaders, demos and projects have now been spell-checked and spelling mistakes/typos corrected.

Changed GenericHID device demo to use the LUFA scheduler, added INTERRUPT_DATA_ENDPOINT and INTERRUPT_CONTROL_ENDPOINT compile time options.

Corrections to the KeyboardHost and MouseHost demos' pipe handling to freeze and unfreeze the data pipes at the point of use.

Fixed Still Image Host SImage_SendData() function not clearing the pipe bank after sending data.

Fixed MagStripe keyboard interface polling interval, increased to 4ms from 2ms to maintain compatibility with Apple MacOS X. Fixed changelog comments on the size of the track buffers when compiling for the AT90USBXXX6/7.

Add new page to the documentation listing existing LUFA powered projects, fix up some inaccuracies in the documentation.

Corrected bitfields -- the smallest datatype required for each bitfield is now used, rather than relying on GCC to truncate unused bytes in bitfields (thanks to Walt Sacuta).

Fixed USBTask.h not conditionally including HostChapter9.h only when CAN_BE_DEVICE is defined (thanks to Ian Gregg).
