Unraid OS 7.3.3 is the latest stable release, bringing security fixes, Linux kernel 6.18.54-Unraid, Docker 29.8.2, ZFS 2.4.4, Unraid API 4.37.5-2, and improvements to File Manager and the WebGUI. We recommend upgrading to receive the security fixes in this release. The changes below are cumulative compared with Unraid OS 7.3.2. Security This release hardens first-time root-password setup and privileged terminal requests, blocks unsafe API-key authorization redirects, improves UPnP remote-access discovery, and safely handles guest-agent content in VM Manager. The cumulative 7.3.3 changelog includes these notable package security updates compared with 7.3.2: OpenSSL 3.5.7 → 3.5.8-2. Samba 4.22.10-2_LT → 4.22.11-2_LT. PHP 8.4.23-1_LT → 8.4.26-1_LT. nginx 1.30.3-1_SBo_LT → 1.30.4-1_SBo_LT. The full 7.3.3 release notes contain the package-by-package changelog and security annotations. Linux Kernel The Linux kernel is updated to 6.18.54-Unraid. Docker Docker engine is updated from 29.5.3 to 29.8.2. Docker Manager retains the shared default icon when a container without its own icon is removed or updated. Thanks to chodeus for this fix. Storage / File Manager ZFS is updated from 2.4.3 to 2.4.4. This release also fixes failures that could interrupt access to user shares or prevent file operations from completing: File Manager copy and move operations to exclusive user shares no longer fail with 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. Names, logs, and other WebGUI values are displayed as text rather than interpreted as HTML. 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 4.37.5-2. See the Unraid API changelog. Base Distro This release updates the underlying system packages with security fixes and maintenance improvements. It includes 319 package updates compared with Unraid OS 7.3.2. See the full release notes for the complete package list. Known Issues No new release-specific known issues are listed. See the 7.3.2 release notes for previously documented issues. Rolling Back See the 7.3.2 release notes for rollback guidance and compatibility limitations.

Unraid 7.4 makes it easier to see what your server is doing and manage what’s running. Track Mover progress, keep background tasks in view, and control your Docker containers’ memory use and network connections - all from the web interface. Unraid 7.4.0-rc.1 is ready for testing ahead of the stable release. This is a release candidate so please install on a test system. Security The cumulative 7.4 changes validate OpenTerminal inputs before shell commands, display guest-agent network-interface names as text, and anonymize public IPv6 addresses in diagnostics. Community contributions also remove curl -k from public notification agents, restoring certificate verification. The 7.4.0-rc.1 release uses the same base package versions as 7.3.3. Notable security-related packages compared with beta.3: OpenSSL 3.5.8-2 - unchanged from beta.3. Samba 4.22.11-2_LT - unchanged from beta.3. PHP 8.4.24-1_LT → 8.4.26-1_LT. nginx 1.30.4-1_SBo_LT - unchanged from beta.3. The release-diff report annotates a pcre2 security update and a util-linux update referencing CVE-2026-78408. See the full release notes for package details. Linux Kernel The Linux kernel advances from 6.18.52-Unraid in beta.3 to 6.18.54-Unraid. Docker You can now connect a container to multiple custom networks. Those connections stay in place when you update or recreate the container. Advanced View adds a memory limit field, giving you control over how much memory each container can use. The Add/Edit form also previews your container’s icon, with a fallback if the image is missing or invalid. Update checks now support OCI images and refresh local image information. Fixes also prevent repeated attempts to load missing icons, preserve the shared default icon, and display the correct creation date for orphaned images. Docker Engine is updated to 29.8.2. Storage / File Manager Mover now shows progress and status, so you can see how file transfers are going. It also preserves hard links between files in different subfolders of the same share. File Manager keeps the source file if a move between shares on different pools or drives fails. Exclusive shares stay under /mnt/user, keeping navigation consistent. Fixes to the user-share filesystem prevent freezes and a crash that could make shares unavailable. Drive identification now supports SGPIO/IBPI-capable controllers when SES is unavailable. You can also start an encrypted array by entering a valid passphrase and pressing Enter. ZFS remains at 2.4.4, rebuilt for the updated Linux kernel. WebGUI / System A new task tray brings background plugin, Docker, and virtual machine operations into one place. Queue tasks and reopen them from any browser tab to check progress. Task windows also adjust to your screen size. Plugin installs now show progress as it happens. Update checks run independently, so one slow plugin no longer holds up the whole page. Plugins with available updates stay at the top, and failed checks show an explanation instead of incorrectly reporting “up to date.” You can configure your server’s physical power button under Settings > Power Settings > Power Button. These settings also work alongside the Dynamix System Buttons plugin. Other fixes License checks retry after temporary connection problems. Stopped arrays show their offline status instead of 100% utilization. Boot-device space usage remains visible when the array is stopped. Networking / Hardware Since beta.3, the firmware inventory adds 12 files for Intel wireless, MediaTek Bluetooth, Marvell, and Realtek Bluetooth hardware. The cumulative 7.4 series also expands Intel, MediaTek, and Realtek wireless support, including RTW88 8812A/8814A/8821A and RTW89 8851BU/8852BU. It adds controller, sensor, and audio-codec support, provides the optional netconsole module, and aligns network defaults with Fedora’s sysctl baseline. Virtualization Unraid 7.4 adds support for running under Hyper-V, including drivers for storage, memory management, keyboards, and communication with the host. This release also fixes an unnecessary warning during VM startup and updates QEMU helper messages. Unraid API Updated dynamix.unraid.net from 4.37.4-5 in beta.3 to 4.37.5-2. See the Unraid API changelog. Base Distro This release updates the underlying system packages with security fixes and maintenance improvements. It includes 41 package updates since beta.3 and uses the same base package versions as Unraid OS 7.3.3. See the full release notes for the complete package list. Known Issues The current rc.1 draft lists no new release-specific known issues and refers to the 7.4.0 release notes for previously documented issues. Rolling Back The current rc.1 draft lists no release-specific rollback warnings. See the 7.4.0 release notes for prior guidance. Upgrading For step-by-step upgrade instructions, see Updating Unraid.

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. Security The release includes hardened root password setup and validation of OpenTerminal request inputs before they reach privileged commands. VM Manager also prevents network-interface names supplied by guests from being interpreted as HTML. The cumulative 7.3.3 changelog includes these notable package security updates compared with 7.3.2: OpenSSL 3.5.7 → 3.5.8-2 — 10 CVEs addressed: CVE-2026-14456, CVE-2026-14457, CVE-2026-18798, CVE-2026-54874, CVE-2026-63072, CVE-2026-63073, CVE-2026-63074, CVE-2026-63075, CVE-2026-63076, and CVE-2026-75803.

PHP 8.4.23-1_LT → 8.4.24-1_LT — 4 CVEs addressed: CVE-2026-7260, CVE-2026-9672, CVE-2026-17543, and CVE-2026-17544. nginx 1.30.3-1_SBo_LT → 1.30.4-1_SBo_LT — CVE-2026-60005. 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.

Unraid OS 7.4.0-beta.3 is available on the next branch. This beta fixes Mover hard-link handling and user-share filesystem issues, includes package and security updates, and updates the Linux kernel to 6.18.52-Unraid. We recommend that beta testers upgrade to receive the included security fixes and help validate the changes. As always, please run beta builds on a test server, not production. What’s New in Beta.3 Mover preserves hard links when progress tracking is enabled, including files in separate subfolders of the same share. shfs no longer deadlocks under concurrent file-lock requests or crashes on an internal unlink assertion that could make /mnt/user unavailable. Includes package updates and security fixes. The following sections highlight cumulative changes compared with Unraid OS 7.3.2, including features introduced in earlier 7.4 betas. Containers / Docker Docker container templates support multiple custom networks, with additional network attachments retained when containers are recreated or updated. The Docker Add/Edit forms preview the container icon URL, with a fallback when the URL is empty or invalid. Advanced View includes a Memory limit field for Docker containers. Registry update checks accept OCI image manifests and indexes. Dashboard icon fallback handling no longer retries indefinitely when the fallback image is unavailable. Storage Mover progress and status tracking is available, with the hard-link preservation fix described above. Drive-location identification supports SGPIO/IBPI-capable controllers when SES is unavailable. File Manager moves between user shares on different pools or drives no longer silently remove the source file when a transfer fails. Stopped arrays show offline and filesystem status instead of 100% utilization, and Boot Device used/free statistics remain visible while the array is stopped. Pressing Enter in an encrypted array passphrase field starts the array when the passphrase is valid. WebGUI / System 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. Configure the physical power button under Settings → Power Settings → Power Button → Physical power button. Foreground task sheets scale with the browser viewport while retaining saved-width and mobile behavior. Plugin update checks run independently, so a slow or unreachable plugin does not hold up the whole Installed Plugins page. Validation failures remain visible with an explanation. License checks retry after transient network or service availability issues. Power Options retains both the Power Mode and Power Button tabs when Dynamix System Buttons is installed, and no longer shows the virtualization warning on bare-metal servers. Networking / Hardware Additional drivers and firmware support Intel, MediaTek, and Realtek wireless hardware. Added support for additional PlayStation, Nintendo, Steam, and Logitech controllers, hardware sensors, and audio codecs. Linux netconsole is available as an optional module for network-based kernel crash diagnostics. Network defaults are aligned with Fedora’s /etc/sysctl.conf baseline. Virtualization Added kernel support for Hyper-V virtualization, including storage, balloon, keyboard, and virtual-socket modules. VM startup no longer logs a PHP deprecation warning when the QEMU location lookup produces no output. Security OpenTerminal validates request inputs before they are used by shell commands. VM Manager displays guest-agent-supplied network-interface names as text rather than active HTML. Diagnostics anonymization hides public IPv6 addresses and related diagnostic output. The cumulative 7.4.0 changelog includes these notable package security updates compared with 7.3.2: OpenSSL 3.5.7 → 3.5.8-2 — 10 CVEs addressed: CVE-2026-14456, CVE-2026-14457, CVE-2026-18798, CVE-2026-54874, CVE-2026-63072, CVE-2026-63073, CVE-2026-63074, CVE-2026-63075, CVE-2026-63076, and CVE-2026-75803.

Thank you to all who contributed to this thread, I’m happy to report that I purchased the ASRock Rack E3C246D4U and paired it with an i5 8500. Using the super secret bios menu mentioned a few pages back (and documented in my linked blog post), I’ve been able to get IPMI and the iGPU working correctly. Also worthy of note is that PCIe bifurcation works well but only in x8x4x4 mode, details in the blog post. This was all achieved using the 2.30 bios and 1.80 bmc firmware. https://blog.ktz.me/asrock-rack-e3c246d4u-the-perfect-media-server-motherboard/

with security advice like this, i'd take this guy seriously. seriously, you guys...

You had as good of an answer as was possible without actually speaking to the project directly, yourself. Seems like a good conclusion to me!

It could but it should be tied into the core docker-engine version from LT so that incompatibilities can be checked for prior any forthcoming releases. As we all know, Docker like to break APIs for fun https://forums.docker.com/t/mismatch-between-api-versions-after-automatic-update-to-1-11-0-beta6-with-docker-machine-on-amazon/8549 There's nothing stop people curl'ing the binary in their go file for now though.

Sorry to revive an old thread. Can we get docker-compose into unraid for real this time?

Official requests go here! Thanks http://feathub.com/linuxserver/linuxserver.github.io

I'm getting fed up of the BS from CrashPlan. There has to be a better solution...

I wouldn't know how to determine that even if it was? Create a new one?

Just a punt but is your docker.img file corrupted?

Testing the update right now. Thanks, much apprieciated.

To add my voice to the cacophony, I too am experiencing the 'cannot connect to engine' error message on the splash screen.

kode, our newest contributor at linuxserver.io just wrote a pertinent article you might find interesting if you're a plugin dev. http://www.linuxserver.io/index.php/2015/07/08/unraid-plugin-authors-automate-the-plg-process-after-committing-to-github/

No problem. One of these days I'll get to fan control. Are the sensors in yellow above or below non critical value? See pic. I had to modify the colours so that the yellow was readable! Red = yellow btw.

Thank you for this plugin. Just installed it with my new Asrock C2750D4I and can confirm it works out the box with no configuration required. Some of my sensors are showing as yellow (the voltages mainly) though. Nice work!

I bought some last year and rather pleased with them 8 months on. Review here http://blog.ktz.me/?p=145

Or a DREMEL! I have the ms800 and its great apart from the amount of room behind the mobo tray for cables. This was the best i could do but I had to leave all data cables in the front 'front' as there was just not enough room. Oh well, makes maintenance easier. I have the norco 5in3 cages with aftermarket fans and drives temps are around 40c. Sent from my Nexus 5 using Tapatalk

Possible been mentioned in this thread before

I think the chances of shoe horning rdm into VB on windoze is far more likely to break than in Linux where it is designed to do this. Sticking with windoze because you're comfortable with it is the pussy option! Be a man, learn how to setup Linux and use the opportunity to learn! Sent from my Nexus 5 using Tapatalk

i once tried this many times, a few years ago and always failed at the raw disk passthrough. how have you dealt with this?

Can you tell us what you are working on? I'm hoping you are focussed on porting addins like the SF stats etc? Or just minor fixes, like the spindown icon which is missing? I'm slowly working through my plugins to make them independent, not relying on SimpleFeatures base plugin. This is a slow process as I'm struggling to find time at the moment. Know the feeling about time! I have a ton of assignments due in for my Uni course in 2 weeks and sleep is a rare thing! Anything the community can help with?
