- MAME
  . VIDEO RENDERING SYSTEM
    . Log script errors at warning level rather than verbose level (plugins\layout\init.lua). Reordered all layouts to place views after element and group definitions and scripts last. This matches how layout files are interpreted by MAME. Fixed various errors identified by validating layout files against an XSD schema.
    . Removed some now unneeded trampolines for flipscreen related functions (bagman.cpp, holeland.cpp, mermaid.cpp, pitnrun.cpp, skyarmy.cpp and zaccaria.cpp)
    . Clarified licensing (opengl\gl_shader_tool.h)
  . UI
    . Update slider list on demand rather than on frame updated. Fixes cycling through BGFX chain effects with tilde menu crashes (ID 08857) (osd\mac\osdmac.h+window.cpp, osd\modules\lib\osdobj_common.cpp+osdobj_common.h, osd\sdl\osdsdl.h+window.cpp and osd\windows\window.cpp/h).
    . Don't rebuild menu just to update one item. Fixes mouse input in Tape Control menu doesn't work (ID 08859). Also automatically rebuild if a script or something changes media underneath. Ensure device monitored for media change is up-to-date (ui\tapectrl.cpp).
    . Fixed issue with focus rotation when filter matches no items (ui\selmenu.cpp)
  . INPUT: Added an SDL lightgun provider. This does essentially the same thing as the Win32 lightgun provider, mapping the absolute pointer position over the window to gun axes (input\input_sdl.cpp). Also added a bunch of const in the windows input handling code.
  . 3rdparty: Updated ASIO to 1.30.2 (3rdparty\asio). Patch config.hpp to hopefully work with strict preprocessor warnings (asio\detail\config.hpp). Set Win32 API version to 0x0600 for Windows SDL builds (osd\sdl_cfg.lua and osd\asio.h).
  . Bumped version, as features that are not in a released version of MAME are now documented (docs\source\*).
  . Documented taps and contention/interruptibility (docs\source\techspecs\memory.rst)
  . Consolidated drivers in single files (dday.cpp, portrait.cpp and powerins.cpp)
- Compiling
  . Fixed a few class memory access warnings (exidy\vertigo_v.cpp, exidy\victory_v.cpp, konami\viper.cpp, sega\saturn_v.cpp, sega\segaic16.cpp, sega\segaic16_road.cpp, seibu\seibucop.cpp, shared\xbox_usb.cpp, sound\spu.cpp, tatsumi\tx1_m.cpp and ussr\tiamc1_a.cpp)
  . Added override qualifiers for overridden virtual member functions (emu\http.cpp and util\server_http_impl.hpp)
  . LUA engine: Work around apparent regression in Clang 18. When taking a pointer to a static member function template in a class template, Clang reports a substitution error if the noexcept specification uses an expression that depends on class template arguments. See https://github.com/llvm/llvm-project/issues/91362. Work around another place where noexcept depends on class template arguments (3rdparty\sol2\sol\sol.hpp).
  . Changed a pointer to a const reference in an API (osd\windows\window.cpp)
  . Removed an array overflow (this is dead code, function never gets called, but GCC 14.1 complained) (MESS) rm380z_v.cpp.
