Minecraft:Density function

• Changed Template:Cd (renamed from Template:Cd)

          • Values at cell vertices always equal the cell value.
        • Template:Cd
          • 2 samples per axis
          • Value is continuous, gradient is constant within a cell but discontinuous across cell boundaries.
          • Values at cell vertices always equal the cell value.

Minecraft:Feature

• Changed Template:Cd and Template:Cd
  • Blocks discarded due to air exposure will no longer fall through to the next replacement rule.

Network Protocol

• Modified Login Protocol
  • Encryption and compression must now be explicitly applied by the server by sending one of two packets that carry connection options.
    • The client must acknowledge the change with a matching packet.
    • Every packet sent and received by the client after the acknowledgement will use the new settings.
    • Previously changes were applied immediately on both sides, which might have lead to malformed packets.
  • Packets that can carry options:
    • Template:Cd (clientbound) and Template:Cd (serverbound).
    • Template:Cd (clientbound) and Template:Cd (serverbound).
