*
* <b>Changed:</b>
* - The TeensyHID bootloader has been removed, per request from Paul at PJRC
* - The LIBUSB_FILTERDRV_COMPAT compile time option in the XPLAINBridge and AVRISP-MKII projects has been renamed
* LIBUSB_DRIVER_COMPAT, as it applies to all software on all platforms using the libUSB driver
* N/A
*
* <b>Fixed:</b>
* - Fixed possible device lockup when INTERRUPT_CONTROL_ENDPOINT is enabled and the control endpoint is not properly
* selected when the ISR completes
* - Fixed AVRISP-MKII clone project not correctly issuing LOAD EXTENDED ADDRESS commands when the extended address
* boundary is crossed during programming or readback (thanks to Gerard Sexton)
* - Fixed warnings when building the AVRISP-MKII clone project with the ENABLE_XPROG_PROTOCOL compile time option disabled
* - Remove incorrect check for the current device state in the Set Configuration request handler of DevChapter9, which broke
* Set Configuration requests to the device under most circumstances.
