* issues in the library. Most of these issues should be corrected in the future release - see
* \ref Page_FutureChanges for a list of planned changes in future releases.
*
* \section Sec_KnownIssuesXXXXXX Version XXXXXX
* - AVR8 Architecture
* - No known issues.
* - UC3 Architecture
* \warning The UC3 device support is currently <b>experimental</b> (incomplete and/or non-functional), and is included for preview purposes only. \n
*
* - No demos, bootloaders or projects have been ported for the UC3 devices in the current release,
* although the architecture is supported in the LUFA core library.
* - DMA transfers to and from the USB controller are not yet implemented for this release.
* - The UC3C, UC3D and UC3L sub-families of UC3 are not currently supported by the library due to their
* altered USB controller design.
* - The various \c *_CreateStream() functions for creating standard \c <stdio.h> compatible virtual file
* streams are not available on the UC3 architecture, due to a lack of suitable library support.
* - XMEGA Architecture
* \warning The XMEGA device support is currently <b>experimental</b> (incomplete and/or non-functional), and is included for preview purposes only.
*
* - Endpoints of more than 64 bytes are not currently supported in this release.
* - Isochronous endpoints are not currently supported in this release. As a result, the audio class
* cannot be used on XMEGA devices.
* - Multiple-bank endpoints are not currently supported in this release.
* - Early silicon revisions of the ATXMEGA128A1U are incompatible with LUFA, due to their various errata
* relating to the USB controller.
* - Architecture Independent
* - The LUFA library is not watchdog aware, and thus timeouts are possible if short periods are used
* and a lengthy USB operation is initiated.
* - No LUFA provided driver INF files for Windows are signed, and thus may fail to install on systems where driver signing is enforced (e.g. Windows 8).
* - Build System
* - No known issues.
* - Atmel Studio Integration
* - Not all devices are listed in the "Supported Parts" screen when selecting a device. To select an alternative device, change the "Show Device" drop-down to "All Parts".
* - When switching boards after changing the device selection, a second conflicting BOARD symbol definition can be created that prevents successful compilation. To fix, open the project properties window (<i>Project->Project {name} Properties...</i> menu item), click the Toolchain tab, click "Symbols" under the "AVR/GNU C Compiler" section and remove the incorrect definition.
* to the next version released. It does not indicate all new additions to the library in each version change, only
* areas relevant to making older projects compatible with the API changes of each new release.
*
* \section Sec_MigrationXXXXXX Migrating from 140302 to XXXXXX
* None
*
* \section Sec_Migration140302 Migrating from 130901 to 140302
* <b>USB Core</b>
* - The \c VERSION_BCD() macro has changed from accepting one floating point parameter to taking three distinct major/minor/revision integer parameters, as
