Changelog

Version: 0.0.5
Date: 2026-06-27

    - Bumped factorio_version to 2.1 and dependency versions accordingly.
    - Minor cleanup following Factorio 2.1 modding guidelines.

Version: 0.0.4
Date: 2026-06-05
  Bugfixes:
    - FIXED: Rail supports could not be placed on Fulgora in the deep oil ocean.
      Cause: The technology "rail-support-foundations" required "elevated-rail".
      Since elevated-rail is disabled by the mod, rail-support-foundations could never
      be researched and the "rail-support-on-deep-oil-ocean" effect was never enabled.
      Fix: Replaced "elevated-rail" with "railway" in the prerequisites for rail-support-foundations.
    - FIXED: rail-planner-allow-elevated-rails modifier was missing in new games.
      The G-switch in the Rail Planner now works correctly after railway research.
  Changes:
    - New control.lua: Existing saves are automatically migrated on load.
      If railway or elevated-rail was already researched, all elevated-rail recipes are
      ensured to be enabled (idempotent, harmless if already active).
    - Code cleanup in vanilla.lua: removed conflicting rail-planner hidden assignments.
    - Updated prototypes/mod-support.lua: Fixed rail-support-foundations and
      rail-planner-allow-elevated-rails in mod compatibility code as well.

Version: 0.0.3
Date: 2025-10-25

    - Updated mod dependency to require boblogistics mod version 2.0.3 or higher for compatibility.
