Changelog

Version: 1.1.0
Date: 2026.04.29
  Changes:
    - Updated mod target to Factorio 2.0
    - Collision layers now registered as CollisionLayerPrototype via data:extend (required by 2.0)
    - Layer names now use underscores per Factorio 2.0 documentation recommendation
    - Rail type detection is now dynamic: covers all types whose name contains "rail" but not
      "signal" (handles straight-rail, curved-rail-a/b, half-diagonal-rail, elevated-* variants,
      legacy-* variants, and modded rail types — curved-rail no longer exists in 2.0)
    - Replaced static copy_all_rails with per-entity backup/restore covering all rail types
    - Collision mask operations now use 2.0 API: mask.layers[name]=true/nil directly
      (add_layer/remove_layer/mask_contains_layer were removed from collision-mask-util in 2.0)
    - cmu.get_mask no longer mutates entities in 2.0; explicit collision_mask assignment added
      before modification to ensure changes persist
    - Verification now checks all detected rail types, not just straight-rail/curved-rail

Version: 1.0.4
Date: 2023.04.04

  Changes:
