On June 1st, 2025, an update to the TrueNAS Apps Catalog will enable per-App IP addressing. This update will also break the ability to automatically migrate Apps from Cobia (23.10) and Dragonfish (24.04) to Electric Eel (24.10.2.2).

TrueNAS Apps in Dragonfish and earlier run on Kubernetes, while Electric Eel Apps run on Docker. The TrueNAS Engineering team developed the automated migration to ensure that upgrades would be simplified and straightforward, which our community embraced by making Electric Eel the fastest-adopted version of TrueNAS ever. With months of refinement and hundreds of fixes behind it, Electric Eel delivers reliable storage and applications and is recommended for even the most mission-critical workloads.

TrueNAS SCALE systems running Cobia (23.10) or earlier should upgrade to Dragonfish (24.04.2.5) and then subsequently to Electric Eel (24.10.2.2) afterwards.

TrueNAS systems with Apps should be upgraded immediately to 24.10.2.2, before June 1st! For users who are not yet running 24.10, the Apps auto-migration will make the process simple to move from Kubernetes to Docker, and users already on 24.10 can simply upgrade to the latest release from within the web UI or by downloading the standalone upgrade bundle from the TrueNAS Community Edition website under the Legacy Version column.

After June 1st, Cobia and Dragonfish users with Kubernetes Apps will need to manually back up and restore their application data and configuration to a new Electric Eel installation. The manual update process is more complex and should be avoided.

Upgrade NOW!

Most TrueNAS systems are already running Electric Eel (24.10) or Fangtooth (25.04) and are already prepared to leverage the new IP addressing capabilities in the June 1st Apps update. Users running NAS-only systems and those running TrueNAS 13.x will not be impacted by this change, but the small percentage of TrueNAS Cobia and Dragonfish systems with Apps – about 5% of TrueNAS systems – will encounter errors attempting to update Apps after this update.

If your system is still running TrueNAS Dragonfish, Cobia, or even earlier – the time to upgrade to Electric Eel is now. There’s no need to upgrade to Fangtooth (25.04) immediately – but upgrading to the newer TrueNAS releases ensures that you receive the latest stability, security, and functionality enhancements.

The TrueNAS team is pleased to announce the release of TrueNAS 24.10.2.2, a minor maintenance release for the TrueNAS “Electric Eel” branch. This maintenance release is designed to enable TrueNAS community users who wish to remain on TrueNAS 24.10 to leverage the upcoming changes to the App Catalog, and benefit from host IP port binding for more flexibility in their App deployments.

Ease of Migration was Key

When we initially delivered TrueNAS 24.10, our user base was overwhelmingly happy with the shift to the new Docker-powered Apps engine, embracing Electric Eel with the fastest uptake in TrueNAS history, eclipsing both TrueNAS 13.0 and 24.04 before it and rocketing to a six-digit deployment count in less than three months after launch.

Part of the ease of adoption of TrueNAS 24.10 was the automatic migration of the Kubernetes and Helm Chart powered applications of the past to the new Docker engine, allowing users to move even complex App configurations with often no manual intervention required. Now, we’re preparing to add even more flexibility to the Apps – and we’re hoping to make it just as seamless again.

Individual Application IP Addressing and Custom Networking

As part of the redesign in the new TrueNAS 25.04 “Fangtooth” update , the TrueNAS engineering team prepared the framework inside Docker and our web UI to enable individual Apps to be assigned their own IP addresses. This would allow customers with specific desires for isolation, traffic balancing, or other advanced networking needs to run their compute workloads as close to their high-performance storage as possible. Making these changes would necessitate some changes to the base framework of the TrueNAS and Docker App engines, and it would mean having to update the individual Apps as well – which would have made them incompatible with the existing TrueNAS 24.10 release.

While we’re excited about the enhanced performance of the unified code base in the newest TrueNAS 25.04 release – and so are the nearly 50,000 users already embracing it – we know that our community appreciates choices, control, and updating at their own pace. That’s why the engineering team made the decision to backport the work done for TrueNAS 25.04 into 24.10.2.2, letting users who leverage the virtualization layers in TrueNAS remain on their version of choice and still benefit from these changes to the Apps ecosystem.

On June 1st, 2025, we’ll be publishing an update to the TrueNAS Apps Catalog that will enable per-App IP addressing on a broad scale. Users on TrueNAS 24.10.2.2 or 25.04 will simply receive a prompt to update their Apps using the usual one-button refresh, and will then have the option to make any advanced networking changes desired. Users on an earlier version of 24.10 will receive an error message – and at this point, should update to 24.10.2.2 — or 25.04 — in order to resolve these and continue forward.

App Migration Deadline is June 1st

For those users still on TrueNAS 24.04 or earlier that have yet to migrate off of the previous Kubernetes powered Apps, please note that the June 1st Apps Catalog update also marks the closing of the automatic Kubernetes to Docker migration period. Upgrades from 24.04 to a newer version of TrueNAS at this time will not be able to migrate their existing Apps automatically, and will require manual reinstallation. After June 1st, users with data in Kubernetes Apps will be encouraged to manually back up and restore their application data and configuration to a new 24.10 based installation, or to move directly to 25.04.

The Choice is Yours To Make

Whether you’re choosing the latest release of TrueNAS or the previous one, both deliver the same rock-solid OpenZFS file system, with the strongest possible data integrity guarantees, the flexibility of RAIDZ expansion, and improved performance resulting from years of development. We’re looking forward to continuing to deliver new features and growing the TrueNAS Community in the future, so don’t hesitate to share your feedback with our team.

You can download the latest TrueNAS 24.10.2.2 update from within the TrueNAS web UI, or directly from our website at https://www.truenas.com/ .

As of April 15, 2025, we were thrilled to announce the official release of TrueNAS 25.04 “Fangtooth”, and with it, a new era begins for the open storage community.

With this launch, we’ve made a small but important change:
TrueNAS SCALE is now officially known as TrueNAS Community Edition.

Why It Matters

This name change is relatively minor in the grand scheme of things, but also a major symbolic milestone that represents how far we’ve come and where we’re going next.

Over the past several years, we’ve maintained two open source branches:

• TrueNAS CORE, based on FreeBSD
• TrueNAS SCALE, built on Linux 

CORE was the original, but as SCALE began to surpass CORE in capability, performance, and quality, there was no reason to continue to maintain two software that served essentially the same purposes and user needs. Maintaining them in parallel also meant dividing our engineering resources and slowing the overall progress of the software. It also required duplicate documentation and support, forums discussions, and often confused new and existing users with questions like:

“What’s the difference between CORE and SCALE?”
“Which one is free?”
“Which version powers Enterprise?”
“Which one should I choose for my use case?”

With CORE being transitioned to its maintenance phase, and the maturation of SCALE, the 25.04 release presented an opportunity to also eliminate the confusion and redundancy by unifying, clarifying, and simplifying. One software. One name. No guesswork.

TrueNAS Community Edition (CE) represents the culmination of a long process of effort consolidation that will only benefit users going forward as we continue to evolve TrueNAS together.

But What Else Has Changed?

Nothing. Just the name. TrueNAS Community Edition is now the singular, free, open source storage platform for non-enterprise users. The unification of CORE and SCALE is complete. The ambiguity is eliminated. And, the TrueNAS Community now has one clear version to rally behind: a version named after them.

For those who have been paying close attention, we’d already been referring to it as “Community Edition” for over 6 months – the 25.04 release just makes it official. And, if you haven’t checked it out yet, the 25.04 release delivers more than ever .

What About TrueNAS Enterprise?

TrueNAS Enterprise continues to be our supported, licensed solution for critical data environments. It’s built on the same codebase as Community Edition, with additional feature enhancements (High Availability, Security, Performance, Enterprise integrations) and full enterprise level support services necessary for production deployments. It is typically provided as turnkey appliances that simplify deployment and are engineered specifically for TrueNAS performance and ongoing support.

Already Using SCALE or CORE?

Good news: You’re already on the path. Fangtooth (25.04) is the first official release with the new Community Edition naming. If you were using SCALE, you’re essentially already using it. If you’re still on CORE, you’ll find a clear evolutionary path forward, and release notes are available to help guide your transition, especially with VM migrations.

One Name. One Path. One Community.

This new name isn’t just easier to say, it’s easier to understand:

• TrueNAS Community Edition = Open source, free, community-supported
• TrueNAS Enterprise = Licensed, supported, and built for production 

Whether you call it TrueNAS Community Edition or TrueNAS CE, it’s clearer, cleaner, and a whole lot easier to explain to the world.

“TrueNAS Community Edition isn’t a reduction, it’s an evolution. Everything users valued in CORE or SCALE is here, and we’re bringing forward even more functionality, security, and innovation in each release cycle.”

— Kris Moore, SVP of Engineering
