πEnd Island
Obsidian pillars, End gateways, the spawn platform, and the portal itself in the middle of the island have all been redesigned.
Dragon does not spawn until a player gets close to the bell tower in the center.
You can still do vanilla respawning mechanic.
Dragon AI is unchanged.

Modified Spawning mechanic
To resummon the dragon, the 4 crystals no longer go right next to the portal. Instead, you'll see 4 bedrock blocks on the floor inside the tower, one in each directional wing of the building. The crystals can be placed on these 4 blocks to start summoning the dragon again.
