Feature work. The headline addition is opt-in Nova host aggregate configuration, giving deployers a way to declare compute aggregates directly in inventory (988882). VAST storage support also expanded on two fronts: a new Manila driver landed alongside Cinder backend improvements that factor out common VAST config options and add support for API token authentication.

Stability. A pair of backports fixes nova-compute startup after a host is reprovisioned, addressing a failure mode where the service would not come back cleanly on rebuilt hypervisors.

Tooling and packaging. The project migrated its build metadata to pyproject.toml, and an AI contribution policy was adopted and backported across four branches. CI marks Debian Trixie jobs non-voting for now, and lint pins saw a routine bump.
