Changelog

Version: 3.2.3
Date: 08. 06. 2026
  Bugfixes:
    - Fixed a bug in Burst Mode where spawners would prematurely stop spawning if a temporary traffic blockage or signal reservation prevented pathing. Spawners now use layout analysis data to only disable themselves if there is a permanent physical track disconnection.
    - Added comprehensive GUI crash-resistance safety checks to verify window validity, child elements, and dropdown selection bounds across Custom Test Builder, color picker, weights, and import/export screen handlers to prevent Lua crashes.

Version: 3.2.2
Date: 08. 06. 2026
  Features:
    - Added support for exporting and importing custom tests alongside benchmark history under a unified JSON structure.
    - Added support for importing single custom test configurations directly via the main control panel.
  Changes:
    - Refactored scenario logic (control.lua and gui.lua) up to the root mod folder to preserve custom tests and benchmark data across mod updates.
    - Reduced the scenario folder code to a lightweight entry stub pointing to the root mod folder.
    - Optimized standard benchmark runs (TFT & Everything Test) by bypassing all custom test lookups, string formatting, and map-wide entity scanning on train spawning and state changes.
    - Added static train composition caching to eliminate dynamic memory allocations during train spawning.
  Bugfixes:
    - Fixed a variable shadowing bug on `imported_tests_count` that prevented custom tests from being registered correctly on import.
