ChangeLog

September 2026: version 1.1.0
        * Add a more complete rulesets SimCity like
        * Manage buget
        * Cleaning code

August 2026: version 1.0.0
        * Switch from MIT to dual licensing (GNU GPLv3 or commercial); see LICENSING.md
        * Ship LICENSE and LICENSING.md in CI and release artifacts; refresh source headers
        * After four years, refresh the whole project :)
        * Update CI: build on Linux, macOS, and Windows; publish release artifacts
        * Implement missing GlassBox concepts: zones, zone rules, opening hours, simulation clock
        * Rename API and script terms for clarity: Area → Zone, Unit → Building ...
        * Buildings are no longer forced onto path nodes; they can stand at an offset along a segment
        * Make routing pluggable (IRouter) and traffic-aware (BPR travel times, Dijkstra router)
        * Many optimizations for large cities, many agents, and many rules (sparse grid, interned
          names, cached travel times, flat router buffers, layer rendering at zoom-dependent
          granularity)
        * Make the ruleset parser more robust
        * Add bundled demo rulesets and sample cities (work in progress)
        * Turn the demo into a full Dear ImGui host application to edit, inspect, and play with a city
        * Add a dedicated city save format (.ogc) with ruleset checksum
        * Add rule logging so failed rule attempts can be inspected in the demo
        * Add extensive documentation (engine, scripts, traffic, demo, integration guide)

January 2022: version 0.2
        * Split the code into a graphics-free library and a separate demo application

October 2020: version 0.1
        * Initial port completed
        * Rendering with SDL2; debugging UI with Dear ImGui
