v0.5.0 — released 2026-08-19

Action required

Neutron no longer falls back to querying Ironic for a baremetal port's
physical_network when it is absent from the port's binding_profile. It is
now a hard requirement: without it, binding a baremetal port is refused and
trunk create and delete operations are rejected with a BadRequest.

Before upgrading, confirm no bound baremetal ports are missing
physical_network, and backfill any that are:

  1. Take a report-only inventory of affected ports in each cloud:

    ./scripts/audit_ports_missing_physical_network.py --os-cloud $CLOUD

  2. If the report lists any ports, backfill them from their Ironic baremetal
    port:

    ./scripts/audit_ports_missing_physical_network.py --os-cloud $CLOUD --execute

  3. Re-run step 1 and confirm it reports no matches.

A port whose trunk parent is still bound but has no physical_network cannot
have its trunk deleted until the profile is corrected. Trunks whose parent port
is unbound are unaffected and delete as before.

v0.4.25 and earlier

Per-version upgrade notes begin with v0.4.26. For earlier versions the only
record is the auto-generated pull request list on the
GitHub releases page.

We have deliberately not reconstructed per-version notes for those releases:
inferring operator impact from pull request titles after the fact produces
confident-sounding instructions nobody has verified. The operator-affecting
changes from before v0.4.26 that are documented have their own guides:
