PLEASE READ AIKAR'S POSTS THROUGHOUT THREAD. SOME THINGS ARE CHANGED.All,There has been a persistent rumour on EMC that Villagers created in 1.7 will keep the old 1.7 trade behavior and only villagers created in 1.8 get the new 1.8 behavior.Well after extensive review, I have to inform you this statement is extremely wrong.What actually happens is that any current trades your villagers have are intended to stay the same and not reset to the new 1.8 trades.However, the Trade Behavior does not differ between the version a villager is created... EVERY Villager, 1.7 or 1.8, has the same new lockout/trade behavior.So even if you had a paper to emerald trade in the last slot, in 1.8 that slot can now become locked, even if it was created in 1.7.However you can re-unlock it by trading other items to the villager. but, the detail about 1.7 trades carrying over... EMC will be removing that due to a bug making 1.7 villagers extremely overpowered compared to 1.8 created ones, potentially resulting in double trades of same item, having double the number of trades compared to a 1.8 spawned villager.This is not a fair bug, and we will not let it remain in place, So all villagers will convert to 1.8 trades. If you had 5 trades, you will have at least 5 on your new villager (maybe 1-2 additional if you get lucky...) -- EDIT: Ignore striked out content - We found a way to not reset existing trades, but still fix the issue with double trades --I know this will upset people who use this detail, but note the concept of an infinite trade villager was already broken by the 1.8 update, not an EMC change, and all information saying they will remain infinite in 1.8 was false.So we recommend anyone trying to create an infinite villager to stop, and note that the concept of them are essentially gone as of 1.8.We will not be changing mechanics to bring back the 1.7 concepts. We are pretty happy with this change in 1.8, as we believe it brings them to be more balanced and encourages trading multiple item types.However, If you get lucky to get a villager with 3+ desirable trades, then I guess you have found a new "infinite villager" as you can just keep rotating the 3 trades to keep unlocking the rest.
