Re-added Pipe_IsEndpointBound() calls to the CDC and RNDIS host class drivers, not that the function has the correct behaviour for devices with bidirectional endpoints.

Add MIME type handling to the Webserver project, so that files of different types (e.g. images) can be served out to HTTP clients.

Added explicit ADC channel masks for the standard set of ADC channels, as the single-ended channel MUX masks are not equal to the channel number on some AVR models. Changed demos to use the new channel masks when using the ADC driver.

Added support to the MIDI Class drivers for packed data, where multiple MIDI events are packed into a single USB packet. Added new MIDI Class driver flush routines to override packing behaviour.

Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.

Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.

Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.

Fixed all Class drivers to ensure they have appropriate guards on each function to ensure the device is enumerated before running, fixed error codes on all guards to return "DeviceDisconnected" where possble.

Renamed HOST_SENDCONTROL_DeviceDisconnect enum value to HOST_SENDCONTROL_DeviceDisconnected to be in line with the rest of the library enum error codes.

Added new ReportType parameter to the HID Device Class driver CALLBACK_HID_Device_CreateHIDReport() callback to indicate the report type to generate.

Corrected the name of the misnamed USB_GetDeviceConfigDescriptor() function to USB_Host_GetDeviceConfigDescriptor().

Added new Printer Host mode ClassDriver demo.

Added table of supported classes and modes to the main USB Class Driver documentation.

Moved USBtoSerial demo the Projects directory, as it is simply an expanded CDC demo. Added const qualifier to Endpoint/Pipe stream write routines.

Added new HID_HOST_BOOT_PROTOCOL_ONLY compile time token to reduce the size of the HID Host Class driver when Report protocol is not needed.

Fixed PrinterHost demo returning invalid Device ID data when the attached device does not have a device ID (thanks to Andrei Krainev).

Remove USE_NONSTANDARD_DESCRIPTOR_NAMES compile time token, split out standard descriptors into seperate USB_Descriptor_* and USB_StdDescriptor_* structures so that both can be used within the one project.

Add guard to the HID Host Class driver SetProtocol command, to ensure that the device supports boot protocol mode before issuing the request.

Add StillImage Host Class Driver functions for opening and closing sessions. Ensure IsActive is set on the interface to allow device functions to run.

Fix spelling of "Received" in all source files where it is misspelt "Recieved".

Add user-filtering to the HID report parser, so that the user code can decide which items are to be stored into the HID_ReportInfo_t structure and which should be discarded to save on RAM usage.

Changed the parameters and behaviour of the USB_GetDeviceConfigDescriptor() function so that it now performs size checks and data validations internally, to simplify user code.

Fixed AVRISP programmer demo -- can now connect to a target and read/write Sig/Lock/Fuse/OSCCAL bytes successfully.

Changed SPI_Init() to allow for the clock polarity and data sample modes to be set.

Changed Dataflash_Init() to no longer call SPI_Init() automatically.

Added V2Protocol handlers to the AVRISP project to enter/exit programming mode, and read/write fuses, lockbits, OSCCAL and Signature bytes.

Added ShutDown functions for all hardware peripheral drivers, so that peripherals can be turned off after use.

Fix issue in CDC device class driver where received data the size of the data endpoint could lock up the driver.

Further work on the new CDC and HID host mode class drivers.

Reset changelog et. al. to reset development information for the new version currently under development.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

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.

State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.

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 TOTAL_NUM_CONFIGURATIONS option, removed USE_SINGLE_DEVICE_CONFIGURATION compile time option (but silently convert it to USE_SINGLE_DEVICE_CONFIGURATION internally for compatibility).

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.

Extend USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch, to add support for multi-configuration devices.

Re-add in simple scheduler for compatibility with legacy code, mark all scheduler related files as deprecated.

Remove ConfigDescriptor.c/.h files from the ClassDriver Host demos, as they will be obsoleted when the Host mode class drivers are complete. Add new StillImage stub class driver common header.

Deleted Host ClassDriver demos -- not yet started, faster to rebase new ClassDriver demos from the newly schedulerless LowLevel host demos rather than re-convert each demo from the previous scheduler-based implementations.

Fixes to MassStorageHost demo to improve compatibility with more USB drives.

Redocumented all device demos, now that they have changed over to the new USB class drivers.

Added C linkage to class drivers for C++ support.

Added prefixes to most of the class driver constants to prevent name clashes.

Deleted StdDescriptors.c, renamed USB_GetDescriptor() to CALLBACK_USB_GetDescriptor, moved ConfigDescriptor.c/.h from the LUFA/Drivers/USB/Class/ directory to LUFA/Drivers/USB/HighLevel/ in preperation for the new USB class APIs.

Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley).

Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code.

Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code.
