Release notes

Arctic Launcher 0.4.4

October 13, 2026

What's new#

Fixed#

  • Server list pings finish: servers no longer sit at "PingingΓǪ" after you come back from a server or open Discover, and Multiplayer no longer crashes while the pings come in.
  • Smooth text without dark edges on 1.17 to 1.21.11 (it was already fixed on 26.1 and newer).
  • Boss bar has its icon in the mods menu, and the Scoreboard and Boss bar settings show a preview even while the real ones are on screen.
  • Continuity and Sodium: a mod that only needs a newer version of another now offers Update first, instead of saying they can't run together.
  • Play together: the invite code wraps inside its card in a narrow window.
  • Theme and client style tiles stay inside their rounded borders.
  • Discover servers: Sort has its own row, so Surprise me no longer covers it.
  • A game that fails before any mod loads (a part of the mod loader that can't be read) starts next time with its files checked and without Arctic's start-up speed-ups, and its crash report says how Java was started.

New#

  • Big modpacks get more memory by themselves when their instance has no memory setting of its own (80+ mods 5 GB, 150+ 6 GB, 250+ 8 GB, never more than your PC can spare).
  • Trash on the Instances page: removed instances are listed there, and you can bring one back in one click or delete it for good.
  • Modpack and mod search keep loading as you scroll down (they stopped at the first 20).
  • Share looks up mods you put in by hand on Modrinth, so mods copied from another folder are shared too.
  • Menu Style is a button next to Edit HUD in the Arctic Client's mods menu.

Cosmetics#

  • Void Brim: the Shadow Brim hat in pure black (Head).
