Changelog

Version: 0.2.5
Date: 2026.10.24
  Changes:
    - Renamed to orbital-transfer-Unofficial-2-1Fix so it can be published next to the original (all prototype, setting and locale names are unchanged, so existing saves keep their chests, research and settings).
    - When added to an existing save, chests on all space platforms are re-registered from the placed entities. In-flight deliveries at the moment of the switch are lost.
Version: 0.2.4
Date: 2026.10.24
  Changes:
    - Factorio 2.1 compatibility (unofficial fork): logistic container animation, opened_duration and animation_sound moved into robot_door.
    - Chests now define default_empty_slots_signal so the new "Read empty slots" circuit option has a signal.
    - Dependencies bumped to base/space-age 2.1.0.
Version: 0.2.3
Date: 2024.11.29
  Changes:
    - For performance reasons, requests are no longer ordered by how long they have been waiting.
    - Added "Render Deliveries" setting defaulting to true. Disabling this can significantly improve performance if you have a lot of chests.
    - Other performance improvements
