Servers

• Added a enable-status option to the Minecraft:server.properties file which if set to false suppresses replies to status requests from clients.
  • This makes the server appear offline in the multiplayer screen.
• Added control over how much entity data a server sends to clients: entity-broadcast-range-percentage server property, controlling how close entities need to be before being sent to clients.
  • Higher values mean entities are visible further away from players but cause more network traffic.
  • Specifies a percentage of the default value so, for example, 50 specifies half of the default range.

• Changed "Game rules" to "Game Rules".
• Changed "Disable Elytra movement check" to "Disable elytra movement check".

Trivia

• The blog post for this update includes an image comparing the prior redstone mechanics to the changed mechanics. Previously, the before mechanics were labeled as 1.15.2 mechanics, despite the presence of a target block, which was introduced later than 1.15.2. The image was later changed to say “Previously” in order to correct this.
  • There is still an error in the caption saying: "Comparison between 1.15.2 and 20w18a"
