· v2026.10.15.6 · e626a727a1 · GitHub ↗

The launcher installs and updates the game — no need to grab these archives by hand. You need your own Minecraft: Java Edition.

New

  • Battery mode: an opt-in 60 FPS cap (30 in menus or unfocused) and half the worker threads (#254)

Fixed

  • perf: reuse renderer entity material batching buffers (#237)
  • perf: return only lighting from chunk light workers (#233)
  • perf(client): reuse parsed model states during preparation (#210)
  • perf(client): share parsed entity models across startup batches (#204)
  • Fix status effect icons and display effects in inventories (#184)
  • perf(client): skip tick chunk synchronization when membership is unchanged (#239)
  • Fix classic title menu layout and accessibility shortcut (#219)
  • perf: reuse unchanged resource-pack overlays after validation (#220)
  • perf(streaming): skip unchanged generation scans (#230)
