[socket-release-bot]

Updates deployment defaults to the published Socket Firewall image 2.9.5 and bumps the Helm chart patch version.

Image: socketdev/socket-registry-firewall:2.9.5
Release run

Manual review is required before merging:

• Review the release changes for configuration or behavioral changes.
• Update deployment documentation and migration examples where needed.
• Check the Helm chart version and CloudFormation defaults, including other pending version PRs.

Note

Medium Risk
Deploys a new firewall image on the supply-chain security path; behavior may differ from 2.9.3 until the linked release is reviewed.

Overview
Bumps the default Socket Registry Firewall container image from 2.9.3 to 2.9.5 and the Helm chart patch from 0.11.7 to 0.11.8.

helm/Chart.yaml updates appVersion and chart version; helm/values.yaml, helm/README.md, cloudformation/firewall-eks.yaml (ChartVersion / FirewallImageTag parameters), cloudformation/values/dns-override.values.yaml, and cloudformation/README.md stay aligned so fresh Helm and EKS CloudFormation installs pull the new image and chart defaults.
