+## 0.6.4+3
+
+* Detect if selected camera supports auto focus and act accordingly on Android. This solves a problem where front facing cameras are not capturing the picture because auto focus is not supported.
+
## 0.6.4+2
* Set ImageStreamReader listener to null to prevent stale images when streaming images.
