Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

  • Filesystem: FS_LoadLibrary extracts native .so/.dll modules from .pk3 into vm/native_cache/ under the game home path (CRC-checked) before dlopen, when com_nativeLibraryExtractPk3 is 1 (default; startup log line).
  • Lua: script_reload falls back to FS_ReadFile + luaL_loadbuffer when a script lives only inside a pack (virtual paths).
  • examples/demo_game: demo_lua.cfg, scripts/lua/demo_hooks.lua, and exec demo_lua.cfg from autoexec.cfg (Lua demo when USE_LUA=ON); pk3 packs both vm/ui<arch>.so and vm/ui.<arch>.so aliases for native UI probe order.
  • Vulkan Forward+: r_forwardPlusLuminanceSort (0/1, archived, default 1); push constant + forward_plus_tile_cull.comp partial selection by RGB sum when a tile exceeds r_forwardPlusMaxPerTile; compile_shaders.sh --apply updates SPIR-V blobs.
  • docs/CURL_NETWORKING.md: tutorial for client libcurl usage (build, cl_dlURL / sv_dlURL, download/dlmap, DLF_* flags, security, extending for MOTD/API/music).
  • Vulkan ImGui: r_imgui cvar (default 1) skips inspector CPU work when 0; startup log line in renderer init; client toggle_imgui command and F11 hardcoded toggle when USE_IMGUI + Vulkan client build.
  • examples/demo_game: idtech3_demo.pk3 embeds a minimal native UI module (vm/ui<arch>.so or .dll) so the demo skeleton can open a window without retail ui.qvm (examples/demo_game/native/ui_skeleton_stub.c, CMake target demo_ui_skeleton).
  • examples/demo_skeleton/: user-friendly demo playfield (./scripts/run_demo.sh, auto-detect layout, baseq3 hint, help text); scripts/run_demo.sh entry point; base/ + idtech3_demo/ README stubs.
  • CTest test_demo_game_pk3: verifies examples/demo_game zip layout (configs + optional cc-built vm/ui*.so) matches CMake staging.
  • Vulkan: vk_procs.c holds qvk* function pointer definitions (split from vk.c); vk_instance.c no longer duplicates extern declarations.
  • Vulkan: vk_shader_modules.c holds vk_create_shader_modules and includes shader_data.c / shader_binding.c (split from vk.c).
  • Vulkan: vk_pipelines_persistent.c holds vk_alloc_persistent_pipelines (split from vk.c).
  • CHANGELOG.md for release tracking
  • Semantic versioning in CMake (project VERSION 1.0.0)
  • ENABLE_FORTIFY_SOURCE option for buffer overflow protection (default ON)
  • ENABLE_ASAN option for AddressSanitizer in Debug builds
  • .editorconfig for consistent editor formatting
  • .clang-format for style enforcement (clang-format -i)
  • docs/MIGRATION.md for upgrade guidance
  • docs/DEPRECATION_POLICY.md for deprecation process
  • Unit test infrastructure: tests/unit/, BUILD_UNIT_TESTS option, unit_macros test
  • compile_engine.sh asan option for local AddressSanitizer builds
  • CI: Clang in Ubuntu build matrix, ASAN job, FORTIFY_SOURCE enabled on Linux

Changed

  • Docs: ARCHITECTURE.md and QUICKSTART.md describe pk3 native library extraction (vm/native_cache/, com_nativeLibraryExtractPk3).
  • Client: clearer message when UI VM fails to load (idtech3_demo ships native UI in vm/, not configs-only).
  • Vulkan Forward+: vk_forward_plus_dispatch_tile_cull passes luminanceSort in push constants; init logs when sort is on.
  • FORTIFY_SOURCE now enabled by default in Release builds (compile_engine.sh)
  • Vulkan cinematic path: r_fboCinematic cvar, vk_in_render_pass reset, luminance skip workaround
  • Vulkan PBR: direct specular uses anisotropic GGX when an anisotropy map is bound (r_pbr_anisotropicSpecular default 1); replaces the old roughness-only blend. Re-run scripts/compile_shaders.sh after changing gen_frag.tmpl.
  • Vulkan PBR: anisotropic visibility for direct light; optional IBL roughness stretch from the anisotropy map (r_pbr_iblAnisoStretch); clearcoat base attenuation and Charlie sheen with optional fourth sheenScale roughness token.

Removed

  • Legacy r_vfog* engine cvars and vk_vfog.c/vk_vfog.h: volumetric fog is configured only via r_volumetricFog* (and map/r_fog* as documented). Editor worldspawn keys vfog_* remain separate map data, not console cvars.

Security

  • _FORTIFY_SOURCE=2 enabled for GCC/Clang Release builds when ENABLE_FORTIFY_SOURCE=ON

1.0.0 - TBD

Initial tagged release. See docs/ROADMAP.md for feature status.
