Greptile Summary

This is an automated release PR promoting Network Operator from v26.4.0-rc.1 to GA v26.4.0, migrating all component image registries from the staging registry (nvcr.io/nvstaging/mellanox) to production registries across all configuration files.

• Registry migration: All components move from nvcr.io/nvstaging/mellanox to nvcr.io/nvidia/mellanox; the network-operator image itself moves to nvcr.io/nvidia/cloud-native, consistent across values.yaml, hack/release.yaml, and the init container patch.
• Version promotion: Chart version, appVersion, and all component image tags drop the -rc.1 suffix and become v26.4.0 / network-operator-v26.4.0; the doca-driver version is unchanged as it was already GA (doca3.4.0-26.04-0.8.6.0-0).
• Sosreport script: Two auto-generated timestamps updated to 2026-06-04T09:58:37Z with no functional changes.

Confidence Score: 5/5

Straightforward GA release promotion with consistent changes across all config files; safe to merge.

All changes are mechanical version and registry substitutions generated by the release automation job. The nvcr.io/nvidia/cloud-native repository for the network-operator image and nvcr.io/nvidia/mellanox for all sub-components are consistent across every affected file (values.yaml, hack/release.yaml, example CRs, and the init container patch). The doca-driver image version intentionally remains unchanged. No logic, schema, or behavioral changes are present.

No files require special attention.

Important Files Changed

Filename	Overview
deployment/network-operator/Chart.yaml	Bumps chart version and appVersion from 26.4.0-rc.1 to 26.4.0 (GA release).
deployment/network-operator/values.yaml	Migrates all component image registries from nvstaging to production; operator image moves to nvcr.io/nvidia/cloud-native while all other components move to nvcr.io/nvidia/mellanox; versions promoted from rc.1 to GA.
hack/release.yaml	Promotes all component versions from rc.1 to GA and migrates repositories from nvstaging to production; NetworkOperator uses nvcr.io/nvidia/cloud-native, all others use nvcr.io/nvidia/mellanox, consistent with values.yaml.
config/manager/init_container_image_name_patch.yaml	Updates init container image reference from staging registry RC to production GA (nvcr.io/nvidia/mellanox/network-operator-init-container:network-operator-v26.4.0).
example/crs/mellanox.com_v1alpha1_nicclusterpolicy_cr-full.yaml	Updates all component repositories from nvstaging to nvcr.io/nvidia/mellanox and versions from rc.1 to GA; doca-driver version unchanged (already GA).
