The bug
Some sounds for a small slime of size 0 seems to have been removed. In game, they no longer produce a sound when they jump in game. The sounds that are affected are:
entity.slime.jump_small
entity.slime.squish_small
You can see that the sound list is empty for both in the sounds.json: http://pastebin.com/raw/RBDamut1
The sound for squish existed in the 1.9-pre2 version however: http://pastebin.com/raw/VygN3QVp
