**Note:** This is a patch release: The container images used in patch releases are integrated with the Apigee hybrid Helm charts. Upgrading to a patch via the Helm chart automatically updates the images. No manual image changes are typically needed.

## Feature
Feature
**Custom environment variables for Guardrail pods (`guardrails.envVars`)**
Starting in version v1.16.3, you can inject custom environment variables into Apigee hybrid Guardrail pods using the new `guardrails.envVars` property in `overrides.yaml`. This is most commonly used to set `NO_PROXY` (or `no_proxy`) so that Guardrail pods bypass a configured forward HTTP proxy when calling internal in-cluster endpoints such as the Kubernetes API server, which previously failed in restricted-network environments with a global `httpProxy` configured. The property is supported on Guardrail pods for the following components: `apigee-datastore`, `apigee-env`, `apigee-ingress-manager`, `apigee-operator`, `apigee-org`, `apigee-redis`, `apigee-telemetry`, and `apigee-virtualhost`.
Example:
```
guardrails:
envVars:
NO_PROXY: 'kubernetes.default.svc,172.20.0.1'
```
