Renamed the the TotalHIDReports element of the HID descriptor structure in the HID class demos to TotalReportDescriptors, to be more accurate of the element's function (thanks to Brian Dickman).

Init function of the Serial driver is now static inline to product smaller code for the common-case of static init.

Minor correction to the DevChapter9.c handling of Set and Clear feature requests -- remote wake up requests now complete correctly rather than stalling the request.

Change device demos to cache the board button values in the same manner as the board joystick to maintain consistency.

Changed HWB board driver to Buttons driver, to allow for the support of future boards with more than one mounted GPIO button.

Fixed missing semicolon in the ATAVRUSBRF01 LED board driver code, changed LED board driver code to define dummy LED masks for the first four board LEDs so that user code can be compiled for boards with less than four LEDs without code modifications (thanks to Morten Lund).

Changed PIPE_CONTROLPIPE_DEFAULT_SIZE from 8 to 64 to try to prevent problems with faulty devices which do not respect the given wLength value when reading in the device descriptor.

Further documentation improvements - removed file view from the main library documentation, replaced file references in the documentation with group references.

Fixed Endpoint_Write_Control_* functions writing more data than expected by the host, causing it to panic (thanks to Johannes Raschke).

Fixed PREVENT ALLOW MEDIUM REMOVAL command issuing in the MassStorageHost demo using incorrect parameters (thanks to Mike Alex).

Fixed MassStorageHost demo broken due to an incorrect if statement test in MassStore_GetReturnedStatus().

Move the length decrements in the pipe and endpoint stream functions to the point at which the buffers are operated on, to prevent decrements during iterations where no data is exchanged (thanks to Francisco Moraes).

Endpoint configuration is now refined to give better output when all configurations have static inputs - removed the now useless STATIC_ENDPOINT_CONFIGURATION compile time token.

Fixed USB_RemoteWakeupEnabled flag never being set (the REMOTE WAKEUP Set Feature request was not being handled).

Renamed the FEATURELESS_CONTROL_ONLY_DEVICE compile-time token to CONTROL_ONLY_DEVICE.

Applied STATIC_ENDPOINT_CONFIGURATION and FIXED_CONTROL_SIZE tokens to all Device mode demos to reduce binary size.

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.
