Version 7.3.0-beta.2 2026-04-01

This beta adds dedicated boot pool support and fixes user-facing regressions reported against 7.3.0-beta.1, especially around Docker behavior, XFS sector-size compatibility, onboarding polish, and device configuration.

This is BETA software. Please use on test servers only.

Upgrading​

For step-by-step instructions, see Upgrading Unraid. Questions about your license?

Known issues​

See Unraid OS Prerelease (Bugs & Feedback) for issues reported by other testers.

  • If you customized /boot/syslinux/syslinux.cfg before switching to internal boot, save a copy first. After migrating, reapply those custom boot settings under Main → Boot Device → Boot → Boot Parameters. If you already migrated, restore syslinux.cfg from backup before reapplying those changes.
  • Adding, removing, and replacing devices in the ZFS boot pool generally works correctly. One exception: if you start with a dedicated boot pool made from two small devices and replace them one at a time with larger devices, the pool may convert to a split pool.
  • When boot-pool devices are added, removed, or replaced, Unraid does not currently update the server BIOS boot priority automatically. After making those changes, verify the BIOS boot order manually.

Rolling back​

  • If you already enabled internal boot or switched to TPM-based licensing while testing the 7.3 prerelease, you can roll back to 7.3.0-beta.1 without issue.
  • Do not roll back to 7.2.4 or earlier after enabling internal boot or TPM-based licensing.
  • If you upgrade ZFS pool features, earlier Unraid releases may not be able to import those pools.
  • If you need to roll back, follow the normal prerelease rollback process before moving between builds.

If you are considering any rollback path below 7.3.0-beta.1, also see the 7.2.4 release notes.

Changes vs. 7.3.0-beta.1​

Containers / Docker​

  • Fix: Preserve user-defined container MAC addresses across Docker restart and system reboot when --mac-address= is set on the primary network. This fixes the beta.1 regression that caused routers and monitoring tools to see duplicate or random replacement MAC addresses after every restart. See the user report.
  • Fix: Hide stale dead or uninspectable "phantom" containers that became newly visible after the Docker 27 → 29 upgrade path. This filters confusing leftovers out of the WebGUI without mutating Docker state. Background: Docker 29 release notes.
  • Fix: Add the missing support needed for Strix Point iGPU Docker workloads on affected systems. See the user report.

Storage​

  • New: Add dedicated boot pool support as a distinct option from split boot pools.
  • Fix: Address sector-size compatibility regressions for 4Kn devices and some LSI HBA setups using 512e disks that affect XFS-formatted array disks.
  • Fix: 4Kn devices formatted XFS with 7.3.0-beta.1 or newer can now be moved out of the array and mounted normally in pools or other Linux systems. Older XFS filesystems that were formatted inside the array on 4Kn disks in previous Unraid releases still cannot be corrected without reformatting.
  • Fix: Make encrypted pools using luks:zfs or luks:btrfs report normal pool status instead of showing UNKNOWN.
  • Fix: Update nfs-utils to eliminate the boot-time nfsrahead abort spam seen on affected systems.
  • Fix: Restore read and write totals for array devices so per-disk counters update correctly again.
  • Fix: Correct the New Config tool so it handles boot pools properly.

WebGUI / System​

  • Improvement: Move the Onboarding Wizard under Tools and add a direct internal-boot device link when setup still needs attention.
  • Fix: Restore the Boot page browse icon on affected systems.
  • Fix: Correct black-theme dropdown visibility in the Onboarding Wizard.
  • Fix: Correct the GMT time zone selection state in the Onboarding Wizard.
  • Fix: Restore the Bind selected to vfio action in System Devices on affected setups.
  • Fix: Stop WebGUI and API requests from spinning up the full HDD array on affected systems.
  • Fix: Restore CPU isolation saving so selected cores apply correctly again.
  • Fix: Persist the built-in rclone configuration in a persistent location across reboot.
  • Fix: Re-add the ReiserFS upgrade block in unRAIDServer.plg so unsupported systems are prevented from updating.
  • Fix: Allow pools that were previously configured as boot pools to be removed correctly.

Unraid API​

Platform updates carried into beta.2​

  • Improvement: The 7.3 prerelease line has been rebased from the previous public 7.3.0-beta.1 baseline through later beta.1.x builds, including a kernel update to 6.18.20-Unraid, Docker 29.3.1, ZFS 2.4.1_6.18.20_Unraid, and an intermediate dynamix.unraid.net update to 4.31.1-126 before the later 4.32.0 bump above.
  • Improvement: Update kernel config for additional AMD XDNA and ACP support, including CONFIG_DRM_ACCEL_AMDXDNA, CONFIG_DRM_AMD_ACP, CONFIG_REMOTEPROC, generic power-domain support, and CONFIG_REMOTEPROC_CDEV.
  • Improvement: Add new AMD NPU firmware, Intel Bluetooth firmware, Intel wireless firmware, and the amdxdna kernel module in the rebased prerelease builds.
  • Improvement: Refresh bundled packages from the original public beta.1 baseline, including updates to bind, btrfs-progs, docker, glib2, gtk+3, mesa, nfs-utils, xfsprogs, and related libraries and tooling.
  • Security: Pick up fixes for multiple bind and libpng CVEs in the rebased prerelease packages.

Full beta.1 changelog retained during the prerelease cycle​

The public beta.1 changelog is retained below for broader 7.3 context while the prerelease cycle is still active, especially the earlier onboarding and licensing changes that still matter during prerelease.

Changes vs. 7.2.4​

Onboarding and internal boot​

New users automatically start in the onboarding wizard, where they choose language, time zone, theme, and activation code settings before selecting a boot option, including internal boot.

Existing users can go to Settings → Onboarding Wizard to review settings and migrate to internal boot.

For details, see Onboarding.

Licensing​

All new and replacement keys use TPM-based licensing when possible because it is more reliable than flash-based licensing.

To proactively switch to TPM-based licensing, see How can I move from flash-based licensing to TPM-based licensing.

Other licensing​

  • Improvement: Improve handling of missing key file states

Storage​

  • New: Show corrupted files in ZFS pool status

  • Fix: Correct mover availability when emptying an array disk with no pool assigned
  • Fix: Correct ZFS pools waking once every 24 hours in affected cases

WebGUI​

  • Improvement: Update many user-facing strings from “Flash” to “Boot”
  • Improvement: Improve organization of boot-related settings

  • Improvement: Improve same-filesystem move operations

  • Fix: Correct path handling issues involving /sub/ in file paths
  • Fix: Correct scrollbar interaction issues during copy or move operations
  • Fix: Correct handling of double quotes in directory names
  • Fix: Correct move and rename edge cases

Virtualization​

  • Improvement: Improve System Devices visibility and VM template workflows
  • Improvement: Improve custom VNC port validation and defaults
  • Fix: Prevent VMs created from user-defined templates from inheriting the source VM MAC address
  • Fix: Correct VM snapshot commit cleanup not updating snapshot metadata correctly
  • Fix: Correct libvirt startup issues encountered during testing

Misc​

  • New: Add Settings → Tailscale stub page for easier plugin discovery
  • Fix: Correct custom image case model handling on the login page
  • Fix: Remove outdated ReiserFS warnings and stale references
