Known issues​

Changes vs. Unraid OS 7.3.2​

Security​

  • Security: Core package updates include security fixes for bind, libXfont2, libarchive, libssh, openssh, p11-kit, php, samba, wpa_supplicant, and xorg-server.
  • Security: Notification integrations now use certificate-verified requests for the public API.

Containers / Docker​

  • New: Docker container templates support multiple custom networks, with additional network attachments retained when containers are recreated or updated.
  • New: Docker Add/Edit forms now show a live preview for the container icon URL, with a fallback when the URL is empty or invalid.
  • New: Advanced View now exposes a Memory limit field for Docker containers.

Storage​

  • Fix: Pressing Enter in encrypted array passphrase fields now starts the array when the passphrase validation succeeds.
  • Fix: File Manager keeps exclusive shares in the /mnt/user/<share> view instead of switching to the underlying disk or pool path.

WebGUI / System​

  • New: Background operations from plugins, Docker, and virtual machines can be queued and managed from a shared task tray, with foreground recall from any browser tab.
  • New: The Boot Device page supports downloading a backup directly or saving it to the server, with progress tracking.
  • New: Physical power-button behavior can be configured for Shut down, Reboot, or Do nothing. Go to Settings → Power Options to configure this.
  • Improvement: Foreground task sheets now scale with the browser viewport while retaining saved-width and mobile behavior.
  • Improvement: License checks now retry if the license becomes unavailable on disk for a minute, this allows for transient boot drive drop outs
  • Improvement: The consolidated header now manages header layout and array-usage display, addressing mobile header overlap.
  • Fix: The Installed Plugins page checks updates independently so a slow or unreachable plugin does not keep the entire page waiting.
  • Fix: Plugin update validation failures now remain visible with an explanation instead of silently reporting the plugin as up-to-date, including failures caused by a full root filesystem.
  • Fix: Plugin Manager post-hook cleanup now runs when error messages contain shell characters.

Networking / Hardware​

  • New: Added kernel modules and firmware for Realtek RTW88 8812A, 8814A, and 8821A wireless adapters.

Virtualization​

  • Fix: VM startup no longer logs a PHP deprecation warning when the QEMU location lookup produces no output.
