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.

This is a bugfix release primarily to address a crash which could happen during periods of network instability on the prior v4.3.0 release.

New Features and Improvements:

• Windowed mode streaming now starts maximized if the GUI window was maximized
• Improved performance when streaming on a local network using IPv6
• Logs on Windows and macOS are now limited by size instead of line count

Bugfixes:

• Fixed crash during specific patterns of audio packet loss
• Windows logs now use CRLF line endings for improved compatibility with text editors
• 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.
