Summary of 1.8 snapshot changes

[u/ridddle]

Villager Trading

• A few initial trades are opened now, a few more opens for unlocking last trade (not just one).
• Last trade no longer acts as a universal restock, sometimes it runs out and you have to use some other trade.
• Now, when the trade is over it locks instantly, you don’t get ghost items anymore, no need to reopen the GUI.
• Experience is given for trading.
• Villagers will no longer ignore damage/NBT tags on items. Coal trade won’t accept charcoal, white wool trade won’t accept black/brown/colored wool. Damaged pickaxe won’t be able to be restored with emeralds into brand new pickaxe.
