A full package-by-package list is in the release notes.

Linux Kernel

The Linux kernel is updated to 6.18.46-Unraid. ZFS and SPL compatibility checks passed against this kernel.

Docker

Docker engine is updated to 29.7.1.

A fix prevents removal of the shared fallback icon when an icon-less Docker container is removed or updated, and stops missing fallback icons from causing repeated failed requests.

WebGUI / System

• New: Configurable physical power-button actions under Settings > Power Options — choose Shut down, Reboot, or Do nothing.
• Fix: With Dynamix System Buttons installed, Power Options now retains both the Power Mode and Power Button tabs.
• Fix: On bare-metal servers, the Power Mode page no longer shows the virtualization warning; virtualized systems continue to show it when applicable.
• Fix: Stopped arrays now show offline or filesystem status instead of 100% utilization, while started arrays retain usage percentages.

Networking / Hardware

Added Intel iwlwifi firmware and Realtek RTW88 driver modules and firmware for additional wireless hardware variants, including 8812A/AU, 8814A/AU, and 8821A/AU devices.

Virtualization

Added kernel support for Hyper-V graphics, ballooning, storage, keyboard, VMBus, utility, and VSOCK components.
