0.0.21a_01[1][2][3][4][5] is a version of Java Edition Classic released on June 23, 2009, at 16:17 UTC to try to fix a "hang bug" by adding a max iterations to the clipping.[6][7]

Fixes

  • Attempted to fix a "hang bug" by adding a max iterations to the clipping.[6][8]
    • However, the game still hangs. As the problem made worse, performance is now much lower than in previous versions.[9]
