QSC Q-SYS Designer 9 current LTS Update Version v9.13.1 (LTS)

Q-SYS 9.13.1 LTS, released 2025-07-31, removes several licensing requirements for Scripting and UCI deployment and resolves many audio, video, control, platform, and management issues. Q-SYS 9.13.0 adds new product support, enhanced GPIO documentation, and camera traffic shaping controls.

• Platform: A security vulnerability related to the SSH service has been addressed.
• Platform: The issue causing certain web page URLs to bypass authentication and potentially expose secure endpoints has been resolved.
• Platform: The issue causing NV-32-H devices to bypass licensing checks, allowing unlicensed units to operate as if licensed, has been resolved.
• Platform: Resolved the issue where pen testing caused high CPU usage on the Core, leading to system lockups and unresponsiveness.

• Numerous audio fixes for QIO, NL, NM, and related devices, including initialization failures, PTP/logging issues, clipping reporting, HTTPS access, redundant failover, and power-supply status reporting.
• Multiple video fixes for NV-21-HU, NV-32-H, NC cameras, and Elo/USB-C workflows, including streaming errors, HDCP issues, USB bridging failures, frame drops, and power-delivery problems.
• Multiple control and UCI fixes, including CSS styling, font rendering, layer behavior, camera preview rendering, script stability, and Designer crashes or freezes.
• Platform stability and reliability fixes, including firmware update failures, memory leaks, runtime crashes, peripheral initialization issues, redundant streaming dropouts, and device reboot/hang conditions.
• Management fixes for packet capture input handling, licensing-related access issues, and Reflect registration memory leaks.

• Scripting Engine license is no longer required to deploy Scripting components to a Core.
• UCI Deployment license is no longer required to deploy a design containing a UCI to a Core.
• The Microsoft Teams Room UC Integration License is no longer required because bundled Scripting and UCI Deployment licenses are no longer needed.
• Q-SYS Capacity Scaling License for Core Nano and Core 8 Flex now combines collaboration and commercial AV scaling, including DSP, 128x128 Q-LAN/AES67 channels, up to 24x24 Media Stream capacity, and up to 48 peripherals.
• New product support for AcousticDesign ceiling mount speakers: AD-C8T-ZB, AD-C8T-SWZB, and AD-C10T-HPZB.
• New NV-1-H-WE network video endpoint support.
• Enhanced GPIO documentation section with improved readability.
• Camera Status > Network now includes a Traffic Shaping toggle for NC cameras.

• Before upgrading, review the Q-SYS Compatibility section to confirm product compatibility.
• If downgrading from version 9.13.x to 9.9.x or earlier, first downgrade to 9.10.x, then proceed to the target version.
• Version 9.13.1 is an LTS release.
• Users can generate an EID containing free UCI Deployment and Scripting Engine licenses if they need to use a version earlier than v10.0.
