• Fixed several platform issues, including USB reset indicator behavior, Word Clock input on Core 110f, inaccurate Core 24f input impedance reporting, Designer crashes on Ctrl+mouse wheel zoom, WAN stream failover behavior, and incorrect color picker preview at hue 360.
• Fixed video issues affecting NC-90 framing, NV-21 decoder fault states, USB bridge glitches, NC-Pro15x privacy preview behavior, Mediacast Router emulation mirroring, NVM direct routing audio pass-through, and privacy behavior with video bridge snapshots.
• Fixed QIO-24f-NA Flex outputs being significantly quieter than line outputs.

• Bulk Peripheral Management for centralized provisioning, certificate management, and peripheral utilities in Core Manager.
• NVM Series video distribution platform with no-code routing and system-wide control panels.
