I applied the update. There was an intermittent software defect that "appears" to be fixed at this point. For some users with older micro sd cards, the index service would intermittently fail and pop up a dialog freezing the UI temporarily with the message: Unfortunately index service stopped. Samsung's Note 3 build of 4.3 was popping up the dialog incorrectly. After several h ours of testing the update, I'm not seeing that error now. I also noticed problems running the Google Drive client that also appear resolved ( again the index service may have been the issue there ?). So far, good news for this update. ATT and Samsung need to do a MUCH better job of tracking issues, defects, fixes and service packs so users can know where their specific issues are and what their options are to resolve those. I had reported the index issue to both ATT and Samsung multiple times over the last month without any meaningful feedback.
