1.13.0 (January 20, 2020) ========================= Changes ------- * access log: added FILTER_STATE :ref:`access log formatters <v1.13.0:config_access_log_format>` and gRPC access logger. * admin: added the ability to filter :ref:`/config_dump <v1.13.0:operations_admin_interface_config_dump>`. * access log: added a :ref:`typed JSON logging mode <v1.13.0:config_access_log_format_dictionaries>` to output access logs in JSON format with non-string values * access log: fixed UPSTREAM_LOCAL_ADDRESS :ref:`access log formatters <v1.13.0:config_access_log_format>` to work for http requests * access log: added HOSTNAME. * api: remove all support for v1 * api: added ability to specify `mode` for :ref:`Pipe <v1.13.0:envoy_api_field_core.Pipe.mode>`. * api: support for the v3 xDS API added. See :ref:`api_supported_versions`. * aws_request_signing: added new alpha HTTP AWS request signing filter * buffer: remove old implementation * build: official released binary is now built against libc++. * cluster: added :ref:`aggregate cluster <v1.13.0:arch_overview_aggregate_cluster>` that allows load balancing between clusters. * config: all category names of internal envoy extensions are prefixed with the 'envoy.' prefix to follow the reverse DNS naming notation. * decompressor: remove decompressor hard assert failure and replace with an error flag. * ext_authz: added :ref:`configurable ability <v1.13.0:envoy_api_field_config.filter.http.ext_authz.v2.ExtAuthz.include_peer_certificate>` to send the :ref:`certificate <v1.13.0:envoy_api_field_service.auth.v2.AttributeContext.Peer.certificate>` to the `ext_authz` service. * fault: fixed an issue where the http fault filter would repeatedly check the percentage of abort/delay when the ``x-envoy-downstream-service-cluster`` header was included in the request to ensure that the actual percentage of abort/delay matches the configuration of the filter. * health check: gRPC health checker sets the gRPC deadline to the configured timeout duration. * health check: added :ref:`TlsOptions <v1.13.0:envoy_api_msg_core.HealthCheck.TlsOptions>` to allow TLS configuration overrides. * health check: added :ref:`service_name_matcher <v1.13.0:envoy_api_field_core.HealthCheck.HttpHealthCheck.service_name_matcher>` to better compare the service name patterns for health check identity. * http: added strict validation that CONNECT is refused as it is not yet implemented.
