My friend asked me to play with him in the new 1.2.13 update. So i joined him and he had the experimental features on but when i went to look in my inventory for stuff i couldn't find it. Well some of it.

(1) The enchanted books are just in the inv next to the tab for them.
(2) Drowned spawnegg is separate and the mob egg tab is doubled.
(3) No trident in inv at all.
(4) Idk if the new prismarine stuff shouldnt be in the slab section but i figured it was supposed to.
(5) No stripped logs.

NOTE: Everything was fine for him.
