openstack/magnum — Week of 2026-07-18

NodeGroup surface. The largest change extends NodeGroup with node_labels and node_taints fields, giving operators per-group control over labels and taints rather than only cluster-wide defaults (988899, ~400 lines). Alongside this, a new microversion 1.13 introduces cluster_id on the API and deprecates the legacy stack_id, nudging the data model away from Heat-centric identifiers.

Packaging and Oslo modernization. Setup configuration migrates to pyproject.toml, with a companion patch adding the file to support pip 23.1. Runtime requirements shed setuptools, and implicit dependencies on importlib_metadata and python-subunit are dropped. On the Oslo side, the deprecated remotable_classmethod is replaced across the versioned-object layer.

Maintenance. CI bumps hacking to 8.1.0, and the REST API Version History docs get a formatting cleanup.

Heat driver retirement. The week is dominated by the removal of drivers/common/templates, deleting roughly 17,000 lines of Heat template machinery from the tree (990148). Devstack gained a helper to copy the kubeconfig from d-p-c k8s-capi, and an old Heat reference was scrubbed from image registration, continuing the shift toward the Cluster API–based path.

API and cluster handling fixes. Project ID validation now goes through a proper API call rather than ad-hoc checks. Cluster template creation no longer falls over when no labels are supplied, and label dicts are now copied rather than shared by reference between clusters and nodegroups — a fix that landed twice in slightly different forms during the week.

CI. The magnum-tempest-plugin job is no longer pulled from master, and the 2026.1 capi_helm job variants have been retired from the gate.
