Release notes

Arctic Launcher 0.5.3

October 25, 2026

What's new#

Fixed#

  • Joining some servers no longer ends in "Network Protocol Error" (SyroMC's shulkers, for one). The Performance switch's Polarium mod (now 0.31.3) asked a mob for its size before the mob was fully made, which the game turned into a lost connection. It now answers as the game does.
