For something as far along as x265, having any single new feature that offers an obvious visual quality improvement is a huge accomplishment. x264 hasn't had one of those since, sheesh, mbtree? Most codec development is about squeezing out a bunch of discreet <<1% compression efficiency gains.

Hmm...recently x264 has added aq-mode=3 into the vanilla build which gives some significant improvements. However that had been in unofficial builds (like tMod or kmod) for years.
