Moonlight

New features:

• Ctrl+Alt+Shift+K has been added to toggle system keyboard grab
• 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

Behavior Changes:

• 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.
• 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.
• 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

Bugfixes:

• Fixed launching in a new VT while a Wayland compositor is running
• Fixed moving focus from the app grid into the toolbar via the gamepad or keyboard
• Fixed a possible crash in the Vulkan renderer when disabling an overlay
• Fixed keyboard grab not working under sdl2-compat on Wayland compositors that lack support for keyboard-shortcuts-inhibit-unstable-v1
• Fixed CLI stream launch causing the saved manual address to be overwritten
• Fixed distinguishing between Enter and Numpad Enter keys (requires updated host software)
• Fixed mDNS discovering unexpected devices after running for a period of time
• Fixed libdecor-gtk window decorations not being displayed on the streaming window
• Updated community-contributed translations from Weblate

New features:

• Experimental YUV 4:4:4 support for improved text clarity during remote desktop usage
• HDR is now supported with software decoding (requires GPU with Vulkan support)
• Bitrate limit can now be increased to 500 Mbps
• Audio decoding now uses 32-bit floating point format

Bugfixes:

• Fixed incorrect color range when streaming with AV1 from a host with an AMD GPU
• Updated community-contributed translations from Weblate

New features:

• HDR to SDR tonemapping is now supported by the Vulkan renderer on Linux

Behavior Changes:

• More time is now provided for PCs to wake up before displaying an error when starting a stream from the CLI
• Moonlight will no longer try to guess VA driver names when running libva 2.20 or later

Bugfixes:

• Fixed crash when the Vulkan renderer executed on a system with no Vulkan devices
• Updated community-contributed translations from Weblate

New features:

• HDR is now supported on Steam Deck and other HDR-capable Linux systems using a new Vulkan-based renderer
• Vulkan Video decoding of H.264, HEVC, and AV1 is now supported using the new Vulkan renderer
• Full E2E stream encryption is now supported when streaming from Sunshine v0.22 or later
• Initiating a stream via the command-line will now automatically wake the target machine if it is sleeping
• Error codes are now displayed in the connection termination dialog
• Detailed PC state information is now available via the new "View Details" context menu option (similar to the Android client)
• The performance overlay can now be configured to be shown by default when starting a stream

Behavior Changes:

• The selected bitrate is no longer silently adjusted by Moonlight based upon the video codec or HDR mode
• The selected mouse mode when starting a stream no longer influences the acceleration curve when the mouse mode is toggled using the Ctrl+Alt+Shift+M key combo while streaming
• Hardcoded fallback paths for VAAPI and VDPAU drivers are no longer used
• Per-session keys (rikey and rikeyid values) are now automatically stripped from logs

• Fixed indefinitely resending mDNS queries when a host could not be resolved
• Fixed inability to pair when the host is not using a RSA-2048 key
• Updated included gamepad mappings
• Updated community-contributed translations from Weblate
