Feature Deprecations
2 minute read.
As part of security hardening and improving feature maintainability, there are occasions when TrueNAS features must be deprecated. Features noted in this article are either no longer receiving any maintenance or, typically due to security vulnerabilities, might be scheduled for removal from TrueNAS in a future major version.
Begin planning migrations from these features immediately and note the TrueNAS upgrade paths required when a deprecated feature is in use.
Due to security vulnerabilities and maintainability issues, the S3 service is deprecated in TrueNAS CORE 13.0 and scheduled for removal in CORE 13.3. Beginning in CORE 13.0-U6, the CORE web interface generates an alert when the deprecated service is either actively running or is enabled to start on boot.
TrueNAS Enterprise
Beginning in CORE 13.0-U6, Enterprise customers with the S3 service running or enabled are prevented from upgrading to the next major version.
Users should plan to move any production data away from the S3 service storage location.
SAS Multipath is supported as-is and receives no further maintenance updates. While multipath situations might be detected and be generally functional in TrueNAS CORE, there is a possibility this is not available in a future TrueNAS CORE major version. Users should avoid creating and managing SAS multipath scenarios with TrueNAS.
Following the upstream FreeBSD 13.2 end-of-life, announced July 1, 2024, virtualization features (plugins, jails, and virtual machines) in TrueNAS 13.0 are now obsolete.
Enterprise users or community users with a critical need to use containers or virtualization solutions in production should migrate to the tested and supported virtualization features available in TrueNAS SCALE. TrueNAS Enterprise customers can contact iXsystems to schedule a TrueNAS 24.04 or newer deployment. See CORE to SCALE Migrations for more information.
