@@ -42,6 +42,7 @@ New Features
 * load balancer: added a :ref:`configuration<envoy_v3_api_msg_config.cluster.v3.Cluster.LeastRequestLbConfig>` option to specify the active request bias used by the least request load balancer.
 * redis: added fault injection support :ref:`fault injection for redis proxy <envoy_v3_api_field_extensions.filters.network.redis_proxy.v3.RedisProxy.faults>`, described further in :ref:`configuration documentation <config_network_filters_redis_proxy>`.
 * tap: added :ref:`generic body matcher<envoy_v3_api_msg_config.tap.v3.HttpGenericBodyMatch>` to scan http requests and responses for text or hex patterns.
+* tcp: switched the TCP connection pool to the new "shared" connection pool, sharing a common code base with HTTP and HTTP/2. Any unexpected behavioral changes can be temporarily reverted by setting `envoy.reloadable_features.new_tcp_connection_pool` to false.
