What's new

1.5.1

New Features

  • The seed search screen is now a unified "Seeds" hub: the seed box with Random and Save buttons lives inside the screen, and results, history, favorites and saved seeds are tabs of one shared list; the old sidebar Seeds list was removed

Improvements

  • Preview maps load and draw noticeably faster: dragging feels more responsive, and the minimap, per-pixel noise effects and the analysis screen are much lighter
  • The saved-seeds workflow works again: the current seed is marked, clicking a saved seed applies it, and saving takes effect immediately
  • Seed search runs on several worker threads for faster hits; typing a new seed re-samples after a short pause instead of on every keystroke

Fixes

  • Fixed the y-intersections view staying black when its data had not been sampled yet
  • Fixed the waypoint naming dialog opening empty and crashing
  • Fixed multi-dimension terrain export flattening deep and tall dimensions
  • Seed searches are more robust: restarting no longer gets blocked by a just-stopped search, a crashed search no longer hangs, and searches no longer time out after 30 seconds
