The latest version of TrueNAS has arrived, and it'll no longer confuse you with CORE and SCALE versions. Instead, the company behind TrueNAS has merged these versions into one release, TrueNAS 25.04.

This new release (Fangtooth) is built on the foundation of Electric Eel (TrueNAS 24.10) and includes features like the Linux kernel 6.12, fast deduplication, 5X acceleration of the RAID-Z expansion process, LXC containers (and Qemu/KVM virtualization) via Incus instances, configurable IP addresses for newly added apps, and more.

There also are several new enterprise extensions, including improved security (GPOS STIC), RDMA extensions for improved latency on iSCSI and NFS, iSCSI block cloning, fast file copy, fiber channel support for enterprise SANs, and NFS access to snapshot directories.

According to the TrueNAS official announcement, "If you are deploying a new TrueNAS system, we recommend TrueNAS 24.10.2.1 for its maturity, broad hardware support, expanded App catalog, better performance, and improved Web UI, all of which make managing TrueNAS easier." However, the announcement adds, "TrueNAS 25.04.0 adds to this and is recommended for Early adopters only." In other words, stick with version 24.10 if you want the most stable option.
