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 ZIP into a new folder and copy the Moonlight Game Streaming Project folder from the older version to preserve your settings and paired hosts.

Important note for Windows Portable upgrades from v6.1.0 or earlier: If you extracted the portable Windows v6.2.0 ZIP file into the same folder as an earlier version of Moonlight, you must delete qopensslbackend.dll file in the tls folder or Moonlight will crash on startup.

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.

Behavior changes:

  • The default renderer on macOS is now libplacebo (using MoltenVK). You can change renderers on macOS in the Advanced Settings.
  • Most video renderers now use full range color instead of limited range
  • The cursor is now also locked to the video area in single display borderless windowed scenarios. This was previously only done in true full-screen mode.
  • The cursor is no longer captured by default in windowed mode. Clicking on the streaming window or pressing Ctrl+Alt+Shift+Z will capture the cursor.
  • Game Mode has been re-enabled on macOS
  • The Metal renderer is supported on Macs with a discrete GPU. It was previously only available on Macs with an iGPU.
  • HDR metadata is now used for tonemapping on macOS. You may need to tweak your HDR brightness in the OS, particularly for external non-Apple displays.
  • CLI output is now displayed in the console on Windows instead of a dialog box
  • GPUs on non-x86 Linux platforms are now assumed to be slow by default, which enables a number of optimizations for improved performance. GL_IS_SLOW=0/VULKAN_IS_SLOW=0 can be set at runtime to override this.
  • Gamepad motion sensors are disabled on Steam Link hardware to help reduce audio glitching caused by high CPU usage. The moonlight.sh script can be edited to re-enable them.
  • The default streaming resolution for new installs is now 1080p instead of 720p.
  • Video bitrate no longer resets when adjusting resolution or frame rate if it's already been manually adjusted

Security:

  • CVE-2026-33546, CVE-2026-33547, and CVE-2026-41210 have been fixed
  • These vulnerabilities could allow a malicious host to crash Moonlight when connecting

New Features:

  • Ctrl+Alt+Shift+K has been added to toggle system keyboard grab
  • D3D11 renderer has been updated to enable VRR support on Nvidia GPUs and improve performance by reducing VRAM copies and allowing overlapping decoding and rendering operations
  • KMSDRM renderer is rewritten to support atomic modesetting, overlays, VRR, ALLM, software decoding, V-sync off with atomic async flip, and more
  • Vulkan rendering is now supported on Linux outside of a desktop environment (KMSDRM)
  • AV1 hardware decoding is now supported on macOS (M3 and later)
  • AppImages now support using the system libva to prevent hardware decoding failure on distros with newer libva versions
  • Added support for DualSense adaptive triggers (requires a compatible host)
  • Gamepads with a second trackpad can now be passed to the host (requires host support)
  • Client identifiers are now provided to the host to allow client-specific session management
  • Added an option to disable pre-launch warnings
  • YUV 4:4:4 video is now supported by the DXVA2 renderer
  • Raspberry Pi 2 and 3 are now officially supported (in addition to Pi 4 and 5 models, which were already supported). 1080p 60 FPS requires overclocking (gpu_freq_min=400) on the Pi 2.

Bugfixes:

  • Reduced background CPU usage
  • Improved startup, settings page, and stream load times
  • Optimized the EGL/GLES renderer to improve performance on low end GPUs and embedded devices
  • Fixed EGL/GLES renderer failures under X11 when GLX was used for the UI

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.
