## Envoy Gateway v1.2.0 Release Notes

**Release Date:** November 6, 2024

The Envoy Gateway v1.2.0 release brings a host of new features, performance improvements, and critical bug fixes to enhance networking, traffic management, and security. Explore the latest changes below.

---

## 🚨 Breaking Changes

- **Gateway API Updates**: Removed `GRPCRoute` and `ReferenceGrant` v1alpha2. [See the Gateway API v1.2.0 documentation](https://github.com/kubernetes-sigs/gateway-api/releases/tag/v1.2.0) for details.
- **CPU Limits**: Removed default CPU limit for Envoy Gateway deployment to avoid throttling.
- **Envoy Shutdown Settings**: Drain strategy set to immediate, with default values as follows:
- `minDrainDuration`: 10s
- `drainTimeout`: 60s
- `terminationGracePeriodSeconds`: 360s
- **Endpoint Health Removal**: Enabled `ignore_health_on_host_removal` for clusters with static endpoints to improve removal speed.
- **Logging Level Adjustment**: Set xDS and Infra IR logs to Debug level instead of Info, so they will no longer appear in Envoy Gateway logs by default. Change logging level to `debug` to view them.

---

## ✨ New Features

### API & Traffic Management Enhancements
- **Gateway-API v1.2.0 Support**: Fully compatible with the latest Gateway-API standards.
- **IPv4/IPv6 Dual Stack**: Now available for EnvoyProxy fleet and `BackendRef` resources.
- **Standalone Mode**: Experimental support for Envoy Gateway standalone (host deployment) mode.
- **JWT Authorization**: Added JWT claims-based authorization in [`SecurityPolicy`](https://gateway.envoyproxy.io/latest/api/extension_types/#securitypolicy) CRD.
- **Response Override**: Added support for `Response Override` and `RequestTimeout` in [`BackendTrafficPolicy`](https://gateway.envoyproxy.io/latest/api/extension_types/#backendtrafficpolicy).
- **Active Passive Failover**: Supported with the new `fallback` field in the [Backend](https://gateway.envoyproxy.io/latest/api/extension_types/#backend) API.
- **Session Persistence in HTTPRoute**: Session persistence is supported in [`HTTPRoute`](https://gateway-api.sigs.k8s.io/reference/spec/#gateway.networking.k8s.io/v1.HTTPRoute) rules for stateful traffic management.
- **HTTPRouteFilter**: Adds support for Direct Response and Path Regex Rewrites in [`HTTPRouteFilter`](https://gateway.envoyproxy.io/latest/api/extension_types/#httproutefilter)

### Security Enhancements
- **JWT Claims-Based Authorization**: Advanced security control with claims-based policies in [`SecurityPolicy`](https://gateway.envoyproxy.io/latest/api/extension_types/#securitypolicy).
- **CORS Wildcard Matching**: Wildcard matching for `AllowMethods` and `AllowHeaders` settings.
- **OIDC Flow Support**: Added nonce support for OIDC authorization.

### Observability & Tracing
- **Datadog Tracing Integration**: Improved support for Datadog tracing in [`EnvoyProxy`](https://gateway.envoyproxy.io/latest/api/extension_types/#envoyproxy) CRD.
- **Access Log Matching**: Filter logs based on custom criteria using `match conditions` in EnvoyProxy.
- **Native Prometheus Metrics**: Introduced a Prometheus metrics endpoint for rate limit monitoring.

### Helm Customization
- **SecurityContext Options**: Customizable security context for improved deployment.
- **NodeSelector and PriorityClassName**: Added for more granular deployment configuration.

---

## 🐞 Bug Fixes

- Fixed xDS translation failure when the WASM HTTP code source was configured without an SHA.
- Resolved unsupported listener protocol types causing errors in Gateway status updates.
- Fixed `BackendTLSPolicy` causing crashes due to invalid `sectionName` in `Backend` configurations.
- Fixed propagation delays in `SecurityPolicy` updates for `HTTPRoute` when using `targetSelectors`.
- Improved `JSONPath` to `JSONPatch` translation accuracy.
- Fixed unwanted `/` appearing in paths when using prefix rewrites.
- Corrected nil pointer errors when configuring hash load balancing.
- Fixed active health check issues where `expectedStatuses` was not functioning properly.
- Ensured correct status updates for `Backend` resources and `HTTPRoute`.

---

## 🚀 Performance Improvements

- **Memory Optimization**: Enhanced memory usage by eliminating redundant resource storage.

---

## ⚙️ Other Notable Changes

- **Envoy Upgrade**: Now using Envoy [v1.32.1](https://www.envoyproxy.io/docs/envoy/v1.32.1/version_history/v1.32/v1.32.1) for added stability and performance.
- **Optional Alpha CRD Watching**: Allows Envoy Gateway to run with older Gateway API versions.

This release strengthens Envoy Gateway with enhanced API support, security policies, and observability features to better serve high-demand environments.
Date: November 06, 2024

## Breaking Changes
- Gateway API GRPCRoute and ReferenceGrant v1alpha2 have been removed
