16w40a is the tenth snapshot for Java Edition 1.11, released to fix some bugs from 16w39c.[1]


  • "Johnny" vindicators are now also created by setting a new byte tag, Johnny, to true, in addition to renaming the vindicator to Johnny. The tag supersedes the name, so a Johnny tag set to 1b will allow arbitrary names with the "Johnny" behavior, or a Johnny tag set to 0b will allow the name Johnny without the "Johnny" behavior.
  • Their axe is now one of their HandItems, whereas before it was purely a visual effect. This means their attack now disables Shields.
  • Vindicators have been heavily buffed - their attack damage on Easy has been increased from 3♥♥ to 7♥♥♥♥, on Normal 5♥♥♥ to 13♥ × 6.5, and on Hard 7♥♥♥♥ to 19♥ × 9.5.
  • Tags xTile, yTile, zTile, inTile and inGround were removed.
  • The life tag is no longer used for anything, but still saved/read.
  • This affects ghast fireballs, blaze fireballs, fire charges, dragon fireballs and wither skulls.
End portal blocks
  • The starfield effect was changed to match that of the end gateway block. It no longer changes perspective with respect to the player, but now remains static with respect to the game screen.
