 ## Change log
 
+### v0.9.4
+* [Feature] Add hand joints support. The SDK will provide information for three additional joints for each hand: HAND, HANDTIP, THUMB.
+* [Feature] Add prediction confidence level for each detected joints.
+* [Feature] Add CPU mode support. By changing the `cpu_only_mode` value in `k4abt_tracker_configuration_t`, now the SDK can run on CPU mode which doesn't require the user to have a powerful graphics card.
+
 ### v0.9.3
 * [Feature] Publish a new DNN model dnn_model_2_0.onnx, which largely improves the robustness of the body tracking.
 * [Feature] Disable the temporal smoothing by default. The tracked joints will be more responsive.
