Added new USB_Host_ConfigurationNumber global variable to indicate the selected configuration in an attached device.
Renamed global state variables that are specific to a certain USB mode to clearly indicate which mode the variable relates to, by changing the USB_* prefix to USB_Device_* or USB_Host_*.
Removed the HOST_STATE_WaitForDeviceRemoval and HOST_STATE_Suspended host state machine states, as these are no longer required.
Altered the USB_Host_SetDeviceConfiguration() function to update the new USB_Host_ConfigurationNumber global as required.
Moved out the Host mode standard request convenience/helper functions from the architecture specific Host driver files to the architecture agnostic HostStandardReq.c driver file.
Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.
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).
Add ORDERED_EP_CONFIG to the device Projects (only) that use only a single class driver, or where the endpoint ordering is fixed, to save on compiled binary size.
Added new GCC_FORCE_POINTER_ACCESS() macro to correct GCC's mishandling of struct pointers.
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).
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 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.
Removed the internal endpoint and pipe memory allocation macros, as this is already performed directly in the code. Simplify the endpoint and pipe reset procedure.
Added command timeout to the AVRISP project so that incorrectly connected targets no longer freeze the device.
Removed string descriptors from the TeensyHID bootloader to reduce its size.
Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.
Minor code cleanups (remove redundant comments, fix spacing, etc.).
Added preprocessor checks to give a human readable error when the class drivers are used when the incompatible NO_STREAM_CALLBACKS compile time option is used.
Fix up demo documentation device compatibility list to be as general as possible to reduce changes required as Atmel releases more devices within the same USB AVR series.
Re-add in flip, flip-ee, dfu and dfu-ee targets to project makefiles (thanks to Opendous Inc.)
Fix allowable F_CPU values comment in project makefiles.
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.
Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.
Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.
Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.
Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
Documented FAST_STREAM_TRANSFERS compile time option.
Reduced the TCP window size for the RNDIS demos (Class and LowLevel) to make them compatible with the AT90USB64x.
Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.
Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.
Added parameter directions to function parameter documentation.
Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).
