Unraid OS 7.3.3-rc.2 is now available on the next branch, bringing security updates, fixes for File Manager and user shares, Linux kernel 6.18.52-Unraid, and Unraid API 4.37.4.

This is a release candidate for prerelease testing so as always, please run it on a test server, not production.

See the full 7.3.3 release notes for the package-by-package changelog and associated CVE references.

Linux Kernel

The Linux kernel is updated to 6.18.52-Unraid.

Docker

Docker engine is updated to 29.7.1 in the cumulative changelog against 7.3.2.

Docker Manager retains the shared default icon when a container without its own icon is removed or updated.

Storage / File Manager

This release addresses failures that could interrupt access to user shares or prevent file operations from completing:

• File Manager copy and move operations no longer fail because of a symlink-depth error.

• The user-share filesystem, shfs, no longer deadlocks when concurrent file-lock requests exhaust its FUSE worker pool.

• An shfs assertion failure that could make /mnt/user unavailable has been fixed.

WebGUI / System

• Configure the physical power button under Settings > Power Options to shut down, reboot, or do nothing.

• Stopped-array utilization is displayed correctly, and used/free statistics remain visible for a mounted Boot Device while the array is stopped.

Networking / Hardware

Additional drivers and firmware support Intel, MediaTek, and Realtek wireless hardware.

Virtualization

Hyper-V kernel support covers graphics, ballooning, storage, keyboard, VMBus, utilities, and VSOCK components.

Unraid API

Updated dynamix.unraid.net to 4.37.4 — see the Unraid API changelog.

Base Distro

Compared with Unraid OS 7.3.2, the cumulative changelog lists 1 package added (ledctl 1.1.0), 1 package downgraded (shared-mime-info to 2.4-3), and 319 packages updated.

• Unraid 7.3.3-rc.2 Release Notes

The Win11 virtual machine has a direct connection to the graphics card but no direct connection to the sound card. The configuration is shown in the figure. When starting the virtual machine normally in Unraid 7.3.2, upgrading to Unraid 7.3.3-rc.2 or Unraid 7.4-beta3 will result in the same virtual machine startup error. The error message is as follows. How can we solve it? Background: Z790+5060Ti, connected to a physical sound card for virtual machine Win11. After shutting down the virtual machine, the webui of Unraid froze, causing the virtual machine to freeze and forcing it to shut down by pressing the power button. Therefore, it has not been connected to a physical sound card and can only be used with a virtual sound card.

The Win11 virtual machine has a direct connection to the graphics card but no direct connection to the sound card.

Please start a new thread in the KVM section and attach diagnostics from Tools → Diagnostics, collected immediately after the failed VM start and before rebooting.

Please also include the complete startup error, the VM log, and the VM XML. Remove private information from the XML before posting.

请在KVM部分开启新帖，并附上从Tools → Diagnostics获取的诊断数据，这些数据是在虚拟机启动失败后、重启前收集的。

请同时附上完整的启动错误、虚拟机日志和虚拟机XML。发布前请删除XML中的私人信息。

Okay, thanks.
