Where TrueNAS Stands Today

25.10 “Goldeye” is the recommended version for new deployments, now at GA. 25.04 “Fangtooth” remains best for mission-critical stability. 24.x & 13.0 are end-of-life — no further updates.

TrueNAS 26 — Annual Releases, No More Fish

A shift to annual releases with simple version numbers (26.1, 26.2…) instead of fish code names. Beta arrives in April 2026 with an extended development cycle for more thorough testing and predictable upgrades.

TrueNAS Connect — Cloud-Style Fleet Management

Unified management for multiple TrueNAS systems, data stays on-prem. Three tiers rolling out through the year:

Foundation (free) — headless setup & config. Plus (Q1, subscription) — replication, Webshare, ransomware protection. Business (Q2) — HA systems, large fleets, MSPs. Early adopters get 50% off the first year.

Hardware — Terabit Networking & Petabyte Density

The R60 brings 5th-gen hardware with 400GbE and RDMA for AI, video editing, and data science. H-Series hybrid systems mix NVMe and HDDs at 80% lower cost per TB than all-flash.

OpenZFS 2.4 adds intelligent tiering — hot data pinned to flash, cold data on spinning disk. With 122TB SSDs now available, a single 1U can house over 1 PB of NVMe storage.

The Bottom Line

The theme is clear: own your data. Predictable costs, no vendor lock-in, open-source foundations you can verify. TrueNAS 26 simplifies the release model, Connect simplifies fleet management, and the hardware lineup covers everything from edge deployments to petabyte-scale AI workloads.
