   *  <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.
