 > Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer-agnostic, and self-contained (no external dependencies).

-### Backend Improvements (PR #9469)
+### Bug Fixes Summary
 
-- **JNI keyboard/clipboard** — Moved ~120 lines of JNI boilerplate from the example into the backend. App code is now just `Init → Loop → Shutdown`.
-- **8 sensor types** — Accelerometer, gyroscope, magnetometer, light, proximity, pressure, humidity, ambient temperature via NDK ASensor API (no JNI).
-- **Display metrics** — DPI, density, xdpi/ydpi, refresh rate, orientation queried via JNI. Auto-scales ImGui style to actual device density.
-- **Clipboard** — Full clipboard support via JNI to Android ClipboardManager.
-- **Zero binaries** — No jar, no wrapper, no .gitignore changes.
+**Merged upstream (3 PRs):**
+- **Android CI** — Pinned Gradle 9.4.1 via `setup-gradle` action, no binaries (#9467)
+- **OpenGL GL_UNPACK state** — Backup/restore `GL_UNPACK_ROW_LENGTH` and `GL_UNPACK_ALIGNMENT` in UpdateTexture() to prevent caller state corruption (#9473)
+- **Android touch release** — Clear mouse position on `AMOTION_EVENT_ACTION_UP` so buttons don't stay hovered (#6627)
+- **SDL2 soft keyboard** — Restored `SDL_StartTextInput()`/`SDL_StopTextInput()` under `#ifdef __ANDROID__` for on-screen keyboard (#7636)
 
-### CI Fix (PR #9467)
+**Open PRs (2):**
+- **OpenGL2 texture destroy** — Defer destruction until `UnusedFrames > 0`, matching all other backends (#9475)
+- **Android backend cleanup** — Move JNI keyboard/clipboard into backend, add display metrics, breaking change to Init() signature (#9469, under review by Omar)
 
-- Uncommented and updated `setup-gradle@v6` action to pin Gradle 9.4.1 (required by AGP 9.2.0).
-- Single 4-line change to `build.yml`, no binaries added.
+## Go Bindings
 
-### Vulkan Fix (PR #9468)
+This fork includes Go (cgo) bindings for Dear ImGui:
 
-- Deep-copy `SurfaceFormat.format` into persistent buffer in `ImGui_ImplVulkan_CreateWindow()` to prevent use-after-free when viewport is destroyed.
-- Follows the same deep-copy pattern already used in `CreateMainPipeline()`.
