* <b>Changed:</b>
* - Core:
* - Android Accessory Host property strings changed from a struct of pointer to an array to prevent unaligned access on greater than 8-bit architectures
* - Audio Device Class driver changed to also require the index of the Audio Control interface within the device, for SET/GET/CUR/MIN/MAX/RES property adjustments
* - Library Applications:
* - Raised the guard bits in the AVRISP-MKII clone project when in PDI and TPI to 32, to prevent communication errors on low quality connections to a target

* <b>Device Mode</b>
* - The device mode Audio Class driver now requires an additional configuration parameter, the Audio Control interface index. Existing applications should
* be adjusted to specify the additional configuration parameter.
*
* <b>Host Mode</b>
* - The Android Accessory Host class driver property strings are now a array of \c char* rather than a struct of named pointers. Existing applications
* should use C99 Designated Initializers with the property string indexes located in \ref AOA_Strings_t instead.
