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:

+
    +
  • 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
    • +
  • Improved readability of the statistics overlay by adding an outline
    • +
  • Improved timing accuracy in the statistics overlay
    • +
  • Improved performance when multiple gamepads are sending input simultaneously
    • +
  • Improved performance when recovering from dropped network packets
    • +
  • Fixed black or green padding being rendered on the bottom or right side of the video stream when streaming from certain hosts
    • +
  • Fixed horizontal scroll direction not being correctly inverted when requested
    • +
  • Fixed Moonlight not exiting after an abnormal stream termination when launched via the CLI
    • +
  • Fixed failure to start on Linux systems where desktop OpenGL is not available
    • +
  • Fixed broken overlay rendering on PowerVR systems using the proprietary driver
    • +
  • Fixed automatic selection of AV1 on systems where HEVC is not available
    • +
  • Fixed instability when using VAAPI decoding under X11
    • +
  • Fixed small deviations in chroma co-siting and color conversion
    • +
  • Fixed suboptimal format selection on some V4L2 decoders
    • +
  • Fixed handling of some non-US keyboard layouts
    • +
  • Fixed stale app list being displayed when using CLI commands
    • +
  • Fixed handling of IPv6 literals that are not URL-escaped
    • +
  • Fixed AV1 Vulkan Video decoding on newer versions of FFmpeg
    • +
  • Fixed Ctrl+C/SIGTERM when running from the console
    • +
  • Fixed several GUI interoperability issues with Qt 6.9 and later
    • +
  • Fixed the IME or software keyboard being unexpectedly displayed in various situations
    • +
  • 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
    • +
