When was the last time Tryndamere was buff/nerfed??

I kind of think he's a little stale. He's been doing the same shit for as long as I've been playing this game. Build crit attack speed and run down two shot your adc. That's how it is I ain't complaining about it just curious to know when his basic ass was touched last. It'd be nice if that reworked him and got him away from that I'mma right click and press R strategy and went with something a little more fitting for a king(he's a king right??) maybe a cool interaction with minions or Ashe.
