+
+**Cash drawer reliability & service binding fixes**
+
+* **Breaking:** `openDrawer()` now completes only once the printer firmware confirms the kick.
+  It previously resolved as soon as the AIDL call was dispatched, so a drawer that never opened
+  still reported success. It now throws a `PlatformException` with code `OPERATION_FAILED`,
+  `PRINTER_EXCEPTION`, `UNAVAILABLE` or `TIMEOUT`.
+* **Breaking:** `drawerStatus()` and `drawerTimesOpen()` no longer return `false` / `0` when the
+  printer service is unreachable — they throw a `PlatformException` with code `UNAVAILABLE`.
+  A dead binding used to be indistinguishable from a drawer that is simply not attached.
+* **Fixed:** Added the `<queries>` declaration for `woyou.aidlservice.jiuiv5` to the plugin
+  manifest. On Android 11+ with `targetSdk >= 30`, package visibility filtering made the Sunmi
+  service invisible, so `bindService()` returned `false` and the printer was reported as
+  "not found" even when installed. Host apps no longer need to declare this themselves.
+* **Fixed:** `BIND_SERVICE` could never resolve. The pending `Result` was only completed from
+  `onServiceConnected`, so a refused or failed bind left the Dart future awaiting forever — which
+  froze app startup for any host that awaited it before `runApp()`. Every exit path now settles
+  the result, including a `false` return from `bindService()`, `onNullBinding` and `onBindingDied`.
+* **Fixed:** The connection is now re-established after `onBindingDied`, and commands that find the
+  service missing schedule a reconnect. Previously a service restart left the plugin permanently
+  broken until the host app was restarted.
+* **Fixed:** `unbindService()` now releases a connection that was requested but never completed,
+  and the plugin cleans up when the Flutter engine detaches.
+* In-flight AIDL callbacks are held with a strong reference so they cannot be garbage collected
+  before the printer replies, and are bounded by a 5s timeout.
