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/ . For more information on when you should update based on your use case, check out the Software Status page with links to important release and upgrade notes.
