Minecraft 1.19.4 Release Candidate 1

Technical Changes

Changes to display entity interpolation:

  • interpolation always starts at the beginning on client tick
  • field interpolation_start is replaced with start_interpolation, with a different meaning
  • start_interpolation describes amount of ticks from the start of next client tick after receiving an update to start of interpolation
    • for example value 0 means that interpolation will start at the beginning of next client tick after receiving the update
  • start_interpolation is not stored in entity data
    • when using data commands, if interpolated value is updated, but start_interpolation is not present in modified tag, interpolation will continue from the time of previous update, but with new values

Fixed bugs in 1.19.4-rc1

  • MC-260857 - Display entities summoned with initial transformation interpolate incorrectly from default transformation during next transformation
