Some things to note:
Netty is screwy so currently can't join single player. @cpw
Crafting has been MAJORY reworked. The current GameRegistry functions are nooped, this is IN THE WORKS.
Just need to move the recipe list to a full class registry, and then re implement the in-code recipe registration.
Also, it IS advised that modders move to JSON, because ideally we'll see a S->C recipe syncing system in 1.13
which would allow servers to have custom recipes.
OreDictionary currently 1/2 works, need to write a better algorithm for replacing ingredients.
Please be patient
Rendering:
A lot of functions got a new float parameter, this is similar to partial ticks, needs more research
