 - ndk/hardware_buffer: Make `HardwareBuffer::as_ptr()` public for interop with Vulkan.
 - **Breaking:** `Configuration::country()` now returns `None` when the country is unset (akin to `Configuration::language()`)
 - Add `MediaCodec` and `MediaFormat` bindings ([#216](https://github.com/rust-windowing/android-ndk-rs/pull/216))
+- ndk/native_window: Use `release`/`acquire` for `Drop` and `Clone` respectively
