      The bug

      When spawned with skulls and soul sand, the wither used to show its bar slowly filling up the health right before it was about to explode and be ready for fight. That is no longer the case in this version. Compare it with 1.8.9 to see the difference. This means also that command blocks are unable to detect the health of the wither.
