    **Improved** the ordering of HTTP and TCP envoy filters to improve consistency
upgradeNotes:
  - title: "Envoy filter ordering"
    content: |
      This change impacts internal implementation of how Envoy "filters" are ordered. These filters run in order to implement various functionality.

# Ext Authz Service

[Ext Authz server](cmd/extauthz) implements the external server for the [Envoy ext_authz filter](https://www.envoyproxy.io/docs/envoy/v1.16.0/intro/arch_overview/security/ext_authz_filter)
as an example of integrating custom authorization system into Istio.

The Ext Authz server supports authorization check request using either HTTP (port 8000) or gRPC v2/v3 (port 9000) API and

    **Removed** support for looking up Envoy extensions in `EnvoyFilter` configuration by name without the typed config URL.

upgradeNotes:
  - title: EnvoyFilter must specify the type URL for an Envoy extension injection.
    content: |
      Previously, Istio permitted a lookup of the extension in `EnvoyFilter` by its internal Envoy name alone. To see if you are affected,

	// EnableMysqlFilter enables injection of `envoy.filters.network.mysql_proxy` in the filter chain.
	// Pilot injects this outbound filter if the service port name is `mysql`.
	EnableMysqlFilter = env.Register(
		"PILOT_ENABLE_MYSQL_FILTER",
		false,
		"EnableMysqlFilter enables injection of `envoy.filters.network.mysql_proxy` in the filter chain.",
	).Get()

	// EnableRedisFilter enables injection of `envoy.filters.network.redis_proxy` in the filter chain.
