 ## 0.9.5 (December 8, 2015)
 
   - This version uses new Lollipop BLE scanning API. Previous API is still supported on older phones. It uses features like batch scanning and hardware filtering (if particular device supports them). No need to change your code, those features are enabled automatically.
