Update: We’ve released a ‘b’ snapshot making End Crystals, End Rods and
Tipped Arrows properly obtainable in Survival. In addition, it fixes numerous
bugs and some crashes.
==============================================================================
We’ve come a long way, but we’re finally approaching The End of the 1.9
snapshot series and are starting to work closer towards a full release.
We’ve now got almost all the features we wanted for 1.9 done and stable,
with a few minor balancing and polishing tasks left to do. In the coming
weeks we will focus more on performance, stability and bug fixing.
Notable changes:
Rebalanced loot found in generated chests (dungeons, for example)
Added new mechanic for respawning the Ender Dragon
New item: End Crystal. Currently drops from Skeletal Horses.
Re-rebalanced the golden apples.
Made the “buff bar” at the top of the screen properly respect
hidden & ambient effects.
Made the new saturation -> food mechanic only apply when you’re not
hungry
Fixed many bugs.
Bones and bone meals are now 50% cooler. No particular reason why,
they just are.

天谴四骑士却是掉末界水晶，好微妙

终界龙重生机制 XD

Bones and bone meals are now 50% cooler.不知道是什么意思

旧的金苹果回来了

50% cooler是彩虹小马的梗，应该是换图？

终界日光灯可以合成了 可是还没写合成材料 (连按F5)

维基上写是 popped chorus fruit 上面摆烈焰棒End crystal 也可以直接合成, 材料是终界眼放中间,幽灵泪放中下, 剩下七格放玻璃
