I don't care what anyone tells me, I get nervous about using a plugin on WP 3.9.2 (soon to be 4.x) when the author has stated its only tested it up to WP 3.8.3. My view is, if the author is not keeping it updated and states it has not tested it with my WP version ~ I use it and it breaks my site ~ I have nobody to blame but myself, and probably no help from the author who is quite within their rights to tell me "What do you expect? I told you so!".
