The Windows installer package may require an Internet connection to download the latest Microsoft Visual C++ Runtime if your PC does not already have it installed. If you do not have Internet access during installation, you can pre-install the runtime from Microsoft's website or use the portable version.

To update an existing installation, simply run the latest installer (for Windows) or replace the old app in your Applications folder (for Mac). For the portable Windows version, extract the latest version on top of your old folder.

To install on Steam Link hardware, extract the ZIP file to the root of a FAT32 flash drive, insert it into your Steam Link, then restart the Steam Link. Moonlight can run alongside official Steam Link streaming and other Steam Link apps.

v4.2.1 is a hotfix release to address a bug in v4.2.0 that prevented streaming from hosts running Sunshine. The original release notes for v4.2.0 are below.

New Features:

• Added support for pairing via the command-line
• Added support for listing installed apps on a host via the command-line
• Improved support for NVIDIA SHIELD and Nintendo game controllers
• Improved handling of V-Sync on Wayland systems to reduce latency
• Improved performance using the legacy non-EGL VAAPI rendering code

Behavior Changes:

• Moonlight now uses D3D11VA decoding by default when streaming in windowed or borderless windowed mode on Windows 10 or later with WDDM 2.0+ drivers
  • D3D11VA allows V-Sync to be fully disabled in borderless windowed mode (and even regular windowed mode on GPUs that support Multi-Plane Overlays)
  • On GPUs with Multi-Plane Overlay support, D3D11VA can provide display latency in windowed mode that is as low as in traditional full-screen mode

Bugfixes:

• Fixed excessive flickering when transitioning from full-screen to windowed mode on Windows
• Fixed streaming window positioning on multi-display macOS systems
• Fixed sporadic crash on macOS while streaming or closing the stream
• Fixed native resolution detection on high DPI Wayland systems
• Fixed audio crackling with SDL 2.24.0 on systems using PulseAudio
• Updated included gamepad mappings
• Updated community-contributed translations

Known Issues:

• Location Services on macOS may cause periodic lag and stuttering on Wi-Fi due to background network scans. To avoid the issue, disable Location Services on your Mac by going to "System Preferences -> Security & Privacy -> Location Services"
• In windowed mode on the Raspberry Pi, video does not move in sync with the window when dragged. This is a limitation of MMAL video overlays.
• In windowed mode on the Raspberry Pi, video will not display while the app does not have focus. This is required to prevent Moonlight's video overlay from rendering on top of other apps.
