Cozystack 1.4: New Dashboard UI, Persistent Tenant Workers, Backup Strategies, and Fractional GPU Sharing

Thu, 21 May 2026 00:00:00 +0000

Cozystack v1.4.0 is now available. The release was published on May 19, 2026, and rolls up every fix shipped in the v1.3.1 to v1.3.3 patch line.

This cycle is focused on the operational experience of running Cozystack as a production platform: a faster dashboard architecture, more durable tenant Kubernetes workers, clearer resource sizing, backup workflows for managed applications, better GPU utilization, safer ingress publishing, and fewer race conditions during first installs and upgrades.

Introducing /cozystack:wizard — a Guided Cozystack Installer

Tue, 19 May 2026 00:00:00 +0000

We’ve shipped /cozystack:wizard — a guided Cozystack installer.

Tell it Talos, Ubuntu, or Existing, and it orchestrates the whole chain end-to-end. It handles cert-SAN traps on NAT’d clouds (OCI, GCP, AWS), ZFS provisioning on Talos, LINSTOR registration races, and a dozen other traps that bit us during real-install testing.

Boot-to-Talos works too: if nodes already came up on base Talos, the wizard upgrades them to the Cozystack-tuned image. The end-to-end path is validated on a 3-node OCI Talos cluster.
