Each listed release links to download files for that release.
Bug tickets are typically accepted for the latest release of the current stable version. Nightly builds also accept feedback and bug tickets.
Nightly builds are automatically published when automated testing passes. .iso files are available for fresh installation on disposable hardware or a virtual machine.
.update files are also available for manually updating an existing experimental system to a nightly build.
Your testing and feedback are always welcome! TrueNAS 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 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 it to the hardware.
This website is a repository of all documentation for TrueNAS projects and related products. The TrueNAS team maintains this documentation and provides regular updates for current and in-development (future) versions of TrueNAS software. For documentation purposes, current and future releases are those recommended by the TrueNAS Software Status page for one or more user types.
Documentation for previous releases no longer recommended for any user type is archived and unmaintained. See the Documentation Archive for content related to these releases.
Update to the latest maintenance release of the current major version before upgrading to the next major version. You can then upgrade directly from the latest maintenance release to the latest release of the next major version.
This chart shows the basic upgrade paths between TrueNAS major versions. Depending on your use case and risk tolerance, you may prefer to delay upgrading to allow additional time for testing and stability. See the TrueNAS Software Status for version recommendations tailored to different user types from Developer to Mission Critical.

Permitted upgrade methods are:
- update: Apply updates using the Update screen in the TrueNAS UI or install a manual update file. Not all upgrade paths support automatic updates (see chart).
- ISO install: Save your TrueNAS configuration file, perform a fresh install using an .iso file for the target version, then upload the saved configuration.
You can skip major versions using a fresh installation with configuration file restore. Before skipping versions, review release notes for each major version to identify service deprecations or significant changes that may affect your configuration. Consider upgrading incrementally through major versions with significant changes, or be prepared to manually reconfigure any incompatibilities after upgrading directly to the target version.
The release names and dates provided here are tentative and can change at any time.
