General

 * Distance effects
 * Item frames no longer follow the camera and jitter with camera rotation at extreme coordinates.
 * Paintings also no longer follow the camera and jitter with camera rotation at extreme coordinates.
 * Fixed a desynchronisation issue that appeared at high coordinates; this varied depending on hardware.
 * In some cases, this simply caused entities, water, ice and the wireframe block outline box to appear slightly desynchronised from the world itself. However, in others, the former grouping would jitter severely.

Trivia

 * 13w41b has the same protocol version as 13w41a, but not compatible with each other.
 * 13w41a was previously removed from the launcher for some time, but was added back in September 2018.
