chore(deps): update dependency protobuf to v4
Metadata
Current evaluation
Renovate PR to bump protobuf ==3.20.3 -> ==4.21.12 was closed unmerged on 2023-01-20; lengau denied it because macaroonbakery required protobuf 3. Renovate ignored4.x afterwards; the bump only landed later via #1639 (v5, commit c3805214).
Resolution: closed not a bug
Reason: Maintainer lengau closed the PR with "Denying this because macaroonbakery requires protobuf 3", and Renovate confirmed the close was intentional (ignore notification for all 4.x releases). The upgrade was therefore invalid at the time due to an upstream dependency constraint, not merged; it was only performed years later in #1639 (commit c3805214, protobuf v5) once macaroonbakery gained protobuf 4/5 support.
