Comment thread
Spokplacenta marked this conversation as resolved.
- Thanks @Spokplacenta !

## 0.8.0

- Add [RemoteFrameBufferWidget.syncLocalClipboardToRemote] (default `true`) to disable pushing the local clipboard to the remote VNC server
- Add [RemoteFrameBufferWidget.onFirstFrame] callback after the first decoded framebuffer is shown
- Fix perpetual loading spinner when ZRLE leaves the internal buffer at zero but a decoded [Image] exists
- Harden [RemoteFrameBufferWidget._decodeAndUpdateImage] with dimension and buffer length checks
- Migrate keyboard handling from deprecated `RawKeyboard` to `HardwareKeyboard`
