 Breaking Changes:

+ - Changed default ImTextureID_Invalid value to -1 instead of 0 if not #define-d.
+    (#9293, #8745, #8465, #7090)
+   - It seems like a better default since it will work with backends storing
+     indices or memory offsets inside ImTextureID, where 0 might be a valid value.
+   - If this is causing problem with e.g your custom ImTextureID definition, you can
+     add '#define ImTextureID_Invalid 0' to your imconfig.h + PLEASE report this to GitHub.
+   - If you have hardcoded e.g. 'if (tex_id == 0)' checks they should be updated.
+     e.g. OpenGL2, OpenGL3 and SDLRenderer3 backends incorrectly had 'IM_ASSERT(tex->TexID == 0)'
+     lines which were replaced with 'IM_ASSERT(tex->TexID == ImTextureID_Invalid)'.
+     If you have copied or forked backends consider fixing locally. (#9295)

   item for layout purpose, even though it draws a 1-pixel separator.

+  - Changed Gamepad mapping for "Activate with Text Input" action: (#8803, #787)

+# How to Build
+
+## Windows with Visual Studio's IDE
+
+Use the provided project file (`example_sdl3_surface.vcxproj`) or open `imgui_examples.sln`.
+
+## Windows with Visual Studio's CLI
+
+Use `build_win32.bat` or directly:
+```bat
+set SDL3_DIR=path_to_your_sdl3_folder
+cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x86 SDL3.lib /subsystem:console
+cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x64 SDL3.lib /subsystem:console
+```
+
+## Linux and similar Unixes
+
+Use the provided `Makefile` or directly:
+```sh
+c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
+  main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
+  -ldl `pkg-config --libs sdl3`
+```
+
+## macOS
+
+Use the provided `Makefile` or directly:
+```sh
+brew install sdl3
+c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
+  main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
+  -framework Cocoa -framework IOKit -framework CoreVideo `pkg-config --libs sdl3`
+```
+
+## Emscripten
+
+Use `Makefile.emscripten`:
+```sh
+source /path/to/emsdk/emsdk_env.sh
+make -f Makefile.emscripten
+```
+
+This produces `web/index.html`, `web/index.js`, and `web/index.wasm`.
