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.

New features:

• Added experimental support for HDR streaming on Windows 10 & 11, Linux, and Raspberry Pi 4 (macOS was already supported)
  • See this link for details on system requirements for HDR
• Added a new key combo for locking the mouse cursor to the window (Ctrl+Alt+Shift+L)
• Added an option to avoid keeping the client display awake while streaming
• Switched to a new decoder implementation on Linux4Tegra (L4T) platforms to improve streaming performance and compatibility with newer JetPack versions

Behavior Changes:

• HDR streaming is now a separate option rather than being part of the Video Codec override dropdown
• HDR streaming is no longer restricted to apps that are certified by NVIDIA as compatible with GameStream HDR
  • Some newer games may require an HDR display or HDR10-compatible EDID emulator dongle connected to your host PC for HDR options to be available

Bugfixes:

• Added workaround for incorrect colorspace on AMD GPUs running recent display drivers
• Fixed higher than expected CPU usage on some older Intel Macs
• Fixed loss of all audio if the active audio device is unplugged while streaming
• Fixed duplicated controllers on some third-party Xbox 360 wireless adapters
• Fixed the GUI being unresponsive after manually quitting when connection to the host is lost
• Fixed the minimize key combo on Windows when streaming in fullscreen mode
• Fixed a rare crash if a controller disconnects right as rumble is starting
• Fixed text rendering on the overlay UI when using SDL_ttf 2.0.18 on Linux
• Fixed incorrect colorspace when using HEVC on Raspberry Pi
• Updated AppImage with libva 2.14
• Updated included gamepad mappings
• Updated community-contributed translations

Known Issues:

• New in v4.0.0 #766: Alt+Tab may not work properly on Windows when streaming in fullscreen or borderless windowed modes. You can use the Ctrl+Alt+Shift+D shortcut as a workaround until a fix is released.
• 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"
• Surface Pro X devices (and possibly other ARM devices) must be upgraded to Windows 10 2004 or later to avoid a video glitch.
• 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.
