Changelog

Version: 0.4.10
Date: 21. 06. 2026
  Bugfixes:
    - Fixed potential crash when merging two neighbouring Trainbuilders with missing surface/position data.
    - Fixed potential crash when rotating a Trainbuilder before render IDs are initialised.
    - Fixed potential crash when renaming a depot via the controller GUI if the controller entity was destroyed.
    - Fixed potential crash when applying locomotive color if the machine tint was not set.
    - Fixed potential crash when opening the controller GUI if the controller entity was invalid or destroyed.
    - Fixed migration cleanup for old Help GUI data and controller builder remapping.
    - Fixed quality input inventory lookup to prefer the Factorio 2.0 crafter_input enum.
    - Fixed changelog formatting errors (duplicate categories in several older versions).

Version: 0.4.7
Date: 21. 06. 2026
  Changes:
    - Removed Factorio 1.1-only optional dependencies from info.json.
    - Kept only optional dependencies that currently have Factorio 2.0 releases or are intended 2.0 compatibility targets.
    - Documented supported Factorio 2.0 optional compatibility targets and removed legacy 1.1-only mods in README.
    - Guarded legacy code may still exist internally where harmless, but unsupported 1.1-only mods are no longer advertised as supported dependencies.

Version: 0.4.6
Date: 21. 06. 2026
  Changes:
    - Audited and hardened legacy optional mod compatibility files.
    - Added safe wrappers around LSlib recipe, technology, and item compatibility edits so missing/renamed optional-mod prototypes are skipped instead of crashing data stage.
    - Added nil guards for old Angel/Bob/AAI/Space Exploration/JunkTrain/FARL compatibility paths.
    - Hardened extra modded train fuel recipe generation when optional fuel items or technologies are missing.
    - Many legacy train mods from Factorio 1.1 are still untested on Factorio 2.0; unsupported/missing prototypes now log and skip rather than abort loading.

Version: 0.4.5
Date: 21. 06. 2026
  Changes:
    - Changed "Allow manual placing of trains" from a startup setting to a runtime-global setting.
  Bugfixes:
    - Manual train placement can now be turned off and on again in an existing save without needing a prototype rebuild/restart.
    - Train item place_result is kept available; script enforcement removes/refunds manually placed rolling stock only when the setting is disabled.

Version: 0.4.4
Date: 21. 06. 2026
  Features:
    - Added Space Age / Quality support: the Trainbuilder captures the quality of the train-part ingredient and creates rolling stock with the same quality.
    - Manual-placement blocking now refunds removed rolling stock with its original quality.
  Changes:
    - Trainbuilder recipes still use a fluid completion marker internally; quality is tracked at runtime from the input item because fluids cannot carry quality.

Version: 0.4.3
Date: 21. 06. 2026
  Features:
    - Added startup setting to allow speed modules in Trainbuilders. Disabled by default.
  Bugfixes:
    - Enforced the manual train placement startup setting at runtime, so manually placed rolling stock is removed when the setting is disabled.
    - Removed the old locomotive-manual-build exception when manual train placement is disabled.
    - Updated EN/DE locale and Tips & Tricks text for the manual train placement and speed module settings.
  Changes:
    - Space Age loads and works on normal planetary rail surfaces. Elevated/diagonal rail building and train quality handling are not explicitly supported yet.

Version: 0.4.2
Date: 21. 06. 2026
  Bugfixes:
    - Rails under/around Trainbuilders stay blueprintable, fixing missing rail pieces when copying/pasting Trainbuilder blueprints.
    - Rails built by robots after a Trainbuilder are kept and protected instead of being destroyed.
    - Removing a rail under a Trainbuilder now removes the invalid Trainbuilder as well to avoid floating builders.

Version: 0.4.1
Date: 21. 06. 2026
  Features:
    - Enabled blueprinting for Trainbuilders, Trainbuilder controllers, and Traindepots.
    - Added pending controller activation for robot/blueprint builds so controllers wait for builders/depots from the same blueprint instead of deleting themselves when built first.
  Bugfixes:
    - Removed the old hidden rail-signal entities used by train controllers and added a migration to destroy existing hidden signals, preventing blinking map markers.

Version: 0.4.0
Date: 21. 06. 2026
  Changes:
    - Fork release for Factorio 2.0 under the internal mod id trainConstructionSiteFork.
    - Visible mod title changed to "Train Construction Site Fork - Factorio 2.0 Update".
    - Added Marcel171297 to the author list and README/Tips & Tricks credits.
    - Added entity event filters for build/remove/death handlers so the mod no longer processes unrelated entity events in large factories.
    - Optimised the construction-site clear check to use one bounded scan for the full builder instead of multiple per-machine/per-type searches.
  Features:
    - Added German locale files.

Version: 0.3.14
Date: 21. 06. 2026

Version: 0.3.12
Date: 21. 06. 2026

    - Added guards around hidden traincontroller signal checks for migrated/script-created controllers.

Version: 0.3.11
Date: 21. 06. 2026
  Bugfixes:
    - Fixed crash from Creative Mod/script_raised_revive when rails are revived on top of train assemblies without a player_index.
    - Normalized train controller direction to 4-way directions and added a nearest-builder fallback so controllers can find builders despite Factorio 2.0 rail/stop snapping offsets.

    - Forced another GUI cache refresh for existing saves after replacing the removed style.

Version: 0.3.8
Date: 21. 06. 2026
  Bugfixes:
    - Forced cached Traincontroller/Traindepot GUI layouts in existing saves to refresh, fixing lingering utility/close_white crashes.
    - Opening depot/controller GUIs now refreshes layout data defensively before creating the GUI.
    - Removing a train controller no longer deletes an already assembled train on the rails.
