What’s new in Workshop v0.9.0¶

Workshop v0.9.0 is the first public release on the 0.9 track. The project is now licensed under the GNU General Public License v3. This release also introduces the workshop init command, a startup firewall check, GPU passthrough via the LXD CDI extension, a redesigned snapshot system, Ubuntu 26.04 support, and arm64 snap builds.

Public release under GPL v3¶

Workshop is now publicly released and licensed under the GNU General Public License v3.

Workshop init command¶

A new workshop init command scaffolds a workshop definition in the current directory, replacing the previous need to copy and adapt boilerplate from another project.

Startup firewall check¶

On startup, Workshop now inspects the host nftables rules that apply to the LXD bridge. If Docker or UFW defaults block forwarding, Workshop logs a message and records a state warning. Workshops still start, so the operator can act before networking issues surface as opaque failures.

GPU passthrough via LXD CDI¶

The gpu interface now uses the Container Device Interface (CDI) extension exposed by recent LXD releases. This aligns Workshop’s GPU passthrough with the mechanism used by the rest of the LXD ecosystem.

Snapshot system overhaul¶

Snapshots are now workshop-agnostic. A snapshot is keyed by its base image and SDK content rather than by the workshop that produced it, so a single snapshot can seed any workshop with a matching base and SDK set.

Ubuntu 26.04 support¶

Workshops can now use ubuntu@26.04 as a base.

arm64 snap builds¶

Workshop is now published to the snap edge channel for arm64 in addition to amd64.
