This is the priority period in which to give us your feedback 137 on features and APIs and file compatibility issues — for all of these, 138 please use the <a href="https://g.co/wearpreviewbug">issue tracker</a>. 139 You can expect some API changes across 140 these updates. 141 </p> 142 143 <p> 144 At milestone 4, you'll have access to the final Android Wear 2.0 145 APIs and SDK to develop with, as well as near-final system images to test 146 system behaviors and features. Android Wear 2.0 will use the Android N 147 API level at this time.
