 ## Changelog
 
+### v1.3.7 (2026.6.26)
+
+**Android Client & Window Capture & Security Hardening**
+
+**New features:**
+- **Android client**: first Android controlled-side client, Android 5.0+ (arm64-v8a / armeabi-v7a); MediaProjection + MediaCodec H.264 streaming; AccessibilityService touch / key injection; D-pad focus navigation for full TV / set-top-box control
+- **Device grouping**: group name embedded at build time via APK binary patch or changed live by the server (`CMD_SET_GROUP`); persisted to `filesDir/yama_group`, survives app restarts
+- **APK build & re-sign**: BuildDlg adds `ghost - Google Android`, same workflow as Linux / macOS ghost; `sign_apk.bat` auto-detects SDK and re-signs
+- **Clean exit on server delete**: BYE command triggers JNI `onNativeExit()` → `stopSelf()`
+- **Foreground window capture**: PrintWindow + server-side HWND routing by clientID, captures the target window even when occluded
+- **View active window from host list**: right-click menu queries and shows the foreground window title of the target machine in real time
+- **TOKEN_AUTH ECDSA signature**: server signs auth responses with its V2 P-256 key to prevent fake-server attacks (`TOKEN_SERVER_VERIFY = 251`)
+- **Anti-cracking version binding**: binary binds to core lib version; mismatched DLL replacement is rejected at load time
+- **Sub-license connection cap**: `LicenseLimit` field in `licenses.ini` + real-time set / clear from `CLicenseDlg` right-click menu
+
+**Improvements:**
+- H264 mode skips the initial ~8 MB raw first-frame; server unlocks display on the first IDR instead
+- Adaptive-size rendering improvements, fewer dimension-change artifacts
+
+**Bug fixes:**
+- `ARGBToNV12` heap overflow on odd-sized windows (clamp dims to even-aligned width/height)
+- Extra screen restarts on connection init (dual fix: client `ScreenManager.cpp` + server `ScreenSpyDlg.cpp`)
+- Memory DLL not restored on client startup
+- Authorization client keyboard log directory conflict (each instance gets its own directory)
+
 ### v1.3.6 (2026.6.14)
 
 **ROI region capture & Web audio streaming & master-UI usability overhaul**
