New HID report item macros (with HID_RI_ prefix) to allow for easy creation and editing of HID report descriptors.

Changed over all project and demo HID report descriptors to use the new HID report item macros.

Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.

Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.

Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.

Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Refactored Host mode Class Driver *_Host_ConfigurePipes() routines to be more space efficient when compiled.

Added new *_ENUMERROR_PipeConfigurationFailed error codes for the *_Host_ConfigurePipes() routines.

Fixed MIDI class driver send routines silently discarding packets if the endpoint or pipe is busy (thanks to Robin Green).

Fix XPLAINBridge code broken during the changes to the Rescue Clock generation in the AVRISP-MKII clone project.

Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Added new NO_CLASS_DRIVER_AUTOFLUSH compile time option to disable automatic flushing of interfaces when the USB management tasks for each driver is called.

The MIDI class drivers now automatically flushes the MIDI interface when the MIDI class driver's USBTask() function is called.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Fixed MIDI_Host_Flush() not aborting early when the specified MIDI host interface was not configured.

Small documentation improvements to explicitly reference tokens in Doxygen, to ensure that they are converted to cross-reference links in the output files.

Fixed LowLevel JoystickHostWithParser demo not saving the chosen HID interface's report descriptor size.

Simplified low level Host demo configuration descriptor parser routines.

Make Printer Host mode Class driver interface descriptor search routine pre-cast the current interface descriptor to simplify the value checks.

Make Host mode Class drivers only set the class driver instance's state values once a compatible interface has been found within the device.

Fix typo in MIDI low level device demo.

Fix low level host mode demos not correctly fetching the next endpoint when an invalid interface is discarded.

Update the pipe configuration routines in the host mode class drivers so that they use the same new code to enumerate compatible devices to increase reliability. Add support to the host mode class drivers for non-sequential (but non-overlapping with other interface) pipe numbers.

Add class name prefixes to missed constants in the class drivers to give all class driver elements a consistent namespace.

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Modified PRNT_Host_USBTask() to flush the output pipe on each call.

Added new PRNT_Host_BytesReceived() and PRNT_Host_ReceiveByte() functions to the Print Host Class driver.

Added new USB_Device_GetFrameNumber() and USB_Host_GetFrameNumber() functions to retrieve the current USB frame number.

Added new USB_Host_EnableSOFEvents(), USB_Host_DisableSOFEvents() and EVENT_USB_Host_StartOfFrame() for the user application handling of USB Start of Frame events while in USB Host mode.

Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible to free up the Start of Frame flag for interrupt use in the user application.

Fixed LowLevel PrinterHost demo not sending control requests to the attached printer with the correct printer interface wIndex value.

Fixed USB_GetHIDReportItemInfo() function modifying the given report item's data when the report item does not exist within the supplied report of a multiple report HID device.

Fix XPLAINBridge project discarding characters from the USB interface due to a double read from the endpoint.

Make XPLAINBridge and USBtoSerial projects more reliable by forcing a flush if the UART-to-USB buffer becomes nearly full.

Reduce locking in the LightweightRingBuffer.h header files by only locking on the update of the buffer count, and require insertions and removals from each buffer to occur in only one execution thread.

Fix CDC_*_ReceiveByte() returning 0 when the interface is not configured, instead of the new -1 error value.

Fix CDC_Host_ReceiveByte() not re-freezing the pipe if no packet has been received.

Remove redundant Pipe token set commands in the CDC and RNDIS host class drivers.

More spell checking of all source files -- correct missed errors, switch to EN-GB spelling dictionary.

Altered the CDC Deivice and Host Class drivers' receive byte routines, so that no data is indicated by a negative return value.

Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer.

Rename reserved members of all structs so that they are uniformly named across all demos/projects/bootloaders.

Added start of the Incomplete TMC demo's command parser code.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

Add new module source variables to the library core makefile, so that module sources can be added to a project's makefile on a per-module rather than per-file basis.

Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.
