Upstream has added the equivalent of our SentientNPC API, with exception to the EnderDragon. We've added Mob to the EnderDragon, and our SentientNPC API should behave the same. Vex#getOwner has been deprecated and a replacement Vex#getSummoner has been added using Mob. However, since 1.13 is not production ready, SentientNPC API is subject for removal in 1.13.1 since 1.13 API is not compatible with 1.12. Please move to the Mob interface ASAP. This update has not been tested by PaperMC and as with ANY update, please do your own testing Bukkit Changes: c5ab54d8 Expand GameRule API ab9a606c Improve entity hierarchy by adding Mob interface.

Subject: [PATCH] Delay Chunk Unloads based on Player Movement
|
|
|
|
When players are moving in the world, doing things such as building or exploring,
|
|
they will commonly go back and forth in a small area. This causes a ton of chunk load
|
|
and unload activity on the edge chunks of their view distance.
|
|
|
|
A simple back and forth movement in 6 blocks could spam a chunk to thrash a
|
|
loading and unload cycle over and over again.
|
|
|
|
This is very wasteful. This system introduces a delay of inactivity on a chunk
|
|
before it actually unloads, which is maintained separately from ChunkGC.
|
|
|
|
This allows servers with smaller worlds who do less long distance exploring to stop
|
|
wasting cpu cycles on saving/unloading/reloading chunks repeatedly.
