  "message": "Upgrade Bazel CI machines (#2689) (#2862)\n\nMigrate Bazel CI runner fleet to C3D instances and scale pools\n\n- Upgrades CI runner pools from `c2-standard-30` to `c3d-standard-30`\nand scales the untrusted fleet sizes to improve build speed and queue\nthroughput.\n- Enables Google Virtual NIC (`GVNIC`) support on all custom runner\nimages. This is mandatory for GCP 3rd-generation machine types (like\nC3D) because they do not support legacy VirtIO networking.\n- Upgrades the base image builder VM to `c3d-standard-8`.",
