Each listed release links to download files for that release. For the latest deployment and update recommendations from iXsystems, see the Software Status page.

Bug tickets are typically accepted for the latest release of the current stable version. Nightly builds also accept feedback and bug tickets.

Nightly Builds

Nightly builds are automatically published when automated testing passes. .iso files are available to fresh install on disposable hardware or a virtual machine. Switching a disposable system from CORE to SCALE typically requires a fresh install using a nightly .iso file.

.update files are also available for manually updating an existing experimental system to a nightly build.

Your testing and feedback is always welcome! TrueNAS SCALE nightlies have an option in the top panel to submit feedback directly to the development team. Let us know what is working well and what can be improved!

Legacy Releases

Legacy TrueNAS versions are provided for historical context and upgrade pathways. They are provided “as-is” and typically do not receive further maintenance releases. Individual releases are within each major version.

Legacy releases can only be used by downloading the .iso file and freshly installing to the hardware. See the Documentation Archive for content related to these releases.
