Was making some changes to my SmartTOP settings, and the m4cconnect application updated itself when I hit the update button. v3.71 was out at the end of June 2014. Nothing new for SLK, so you don't need to update your unit.
From the changelog:
2014-06-29 Fix for rare case where trunk lid doesn't fully close on SL after remote top close - v3.71
