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.
Fixed lack of support for the ATMEGA32U2 in the DFU and CDC class bootloaders
Changed incomplete Webserver project over to using the uIP timer library.
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.).
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.
Added warning to the EVENT_USB_Device_Connect() and EVENT_USB_Device_Disconnect() events that they may be fired multiple times during device enumeration on the series 2 AVRs.
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.
Added new USE_FLASH_DESCRIPTORS compile time option. By default, descriptors can now lie in mixed memory spaces (specified by a new parameter to the CALLBACK_USB_GetDescriptor() function) unless one of the USE_*_DESCRIPTORS compile time option is specified.
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).
Remove all Host mode class demos other than the CDCHost class driver demo, so that they can be re-added as they are made once the host mode class framework is designed.
Fixed USB_Host_SendControlRequest() not re-suspending the USB bus when initial device ready-wait fails.
Fixed USB Pad regulator not being disabled on some AVR models when the USB_OPT_REG_DISABLED option is used.
