Software Lifecycle

TrueNAS Quality Lifecycle

TrueNAS releases follow a general adoption guideline for their lifetime. Starting with the NIGHTLY builds, each stage of a major release incorporates more testing cycles and bug fixes that represent a maturation of the release. With each version release stage, users are encouraged to install, upgrade, or otherwise begin using the major version, depending on the specific TrueNAS deployment and use case:

Release StageCompleted QA CyclesTypical UseDescription
ALPHA1TestersNot much field testing
BETA2EnthusiastsMajor Feature Complete, but expect some bugs
RC4Home UsersSuitable for non-critical deployments
RELEASE6General UseSuitable for less complex deployments
U17Business UseSuitable for more complex deployments
U2+8Larger SystemsSuitable for higher uptime deployments

The Software Status page shows the latest recommendations for using the various TrueNAS software releases.

Upgrade Notes

  • TrueNAS SCALE is an appliance built from specific Linux packages. Attempting to update SCALE with apt or methods other than the SCALE web interface can result in a nonfunctional system.

  • All auxiliary parameters can change between TrueNAS major versions due to security and development changes. We recommend removing all auxiliary parameters from TrueNAS configurations before upgrading.

  • After updating, clear the browser cache (CTRL+F5) before logging in to SCALE. This ensures stale data doesn’t interfere with loading the SCALE UI.
