.. _version_history_1.5.0: 1.5.0 (December 4, 2017) ========================= Changes ------- * **access log**: added fields for :ref:`UPSTREAM_LOCAL_ADDRESS and DOWNSTREAM_ADDRESS <v1.5:config_access_log_format>`. * **admin**: added :ref:`JSON output <v1.5:operations_admin_interface_stats>` for stats admin endpoint. * **admin**: added ``version_info`` to the :ref:`/clusters admin endpoint <v1.5:operations_admin_interface_clusters>`. * **admin**: added basic :ref:`Prometheus output <v1.5:operations_admin_interface_stats>` for stats admin endpoint. Histograms are not currently output. * **config**: added --v2-config-only CLI flag. * **config**: the :ref:`v2 API <v1.5:config_overview_v2>` is now considered production ready. * **cors**: added :ref:`CORS filter <v1.5:config_http_filters_cors>`. * **envoy**: Many small bug fixes and performance improvements not listed. * **health check**: added :ref:`reuse_connection <v1.5:envoy_api_field_HealthCheck.reuse_connection>` option. * **health check**: added :ref:`x-envoy-immediate-health-check-fail <v1.5:config_http_filters_router_x-envoy-immediate-health-check-fail>` header support. * **http**: added :ref:`per-listener stats <v1.5:config_http_conn_man_stats_per_listener>`. * **http**: end-to-end HTTP flow control is now complete across both connections, streams, and filters. * **listeners**: added :ref:`drain_type <v1.5:envoy_api_field_Listener.drain_type>` option. * **load balancer**: added :ref:`subset load balancer <v1.5:arch_overview_load_balancer_subsets>`. * **load balancer**: added ring size and hash :ref:`configuration options <v1.5:envoy_api_msg_Cluster.RingHashLbConfig>`. This used to be configurable via runtime. The runtime configuration was deleted without deprecation as we are fairly certain no one is using it. * **log**: added the ability to optionally log to a file instead of stderr via the :option:`--log-path` option. * **lua**: added experimental :ref:`Lua filter <v1.5:config_http_filters_lua>`. * **mongo filter**: added :ref:`"drain close" <v1.5:arch_overview_draining>` support. * **mongo filter**: added :ref:`fault injection <v1.5:config_network_filters_mongo_proxy_fault_injection>`. * **outlier detection**: added :ref:`HTTP gateway failure type <v1.5:arch_overview_outlier_detection>`. See `deprecated log <https://github.com/envoyproxy/envoy/blob/v1.5.0/DEPRECATED.md>`_ for outlier detection stats deprecations in this release. * **redis**: added :ref:`"drain close" <v1.5:arch_overview_draining>` functionality. * **redis**: the :ref:`redis proxy filter <v1.5:config_network_filters_redis_proxy>` is now considered production ready. * **router**: added :ref:`configuration <v1.5:envoy_api_field_RouteAction.cluster_not_found_response_code>` to return either a 404 or 503 if the upstream cluster does not exist. * **router**: added :ref:`cookie hashing <v1.5:envoy_api_msg_RouteAction.HashPolicy.Cookie>`. * **router**: added :ref:`custom request headers <v1.5:config_http_conn_man_headers_custom_request_headers>` for upstream requests. * **router**: added :ref:`downstream IP hashing <v1.5:envoy_api_field_RouteAction.HashPolicy.connection_properties>` for HTTP ketama routing. * **router**: added :ref:`regex <v1.5:envoy_api_field_RouteMatch.regex>` route matching. * **router**: added :ref:`start_child_span <v1.5:envoy_api_field_filter.http.Router.start_child_span>` option to create child span for egress calls. * **router**: added :ref:`x-envoy-overloaded <v1.5:config_http_filters_router_x-envoy-overloaded>` support. * **router**: added complete :ref:`custom append/override/remove support <v1.5:config_http_conn_man_headers_custom_request_headers>` of request/response headers. * **router**: added optional :ref:`upstream logs <v1.5:envoy_api_field_filter.http.Router.upstream_log>`. * **router**: added support to :ref:`specify response code during redirect <v1.5:envoy_api_field_RedirectAction.response_code>`. * **runtime**: added :ref:`comment capability <v1.5:config_runtime_comments>`. * **server**: change default log level (:option:`-l`) to ``info``. * **stats**: maximum stat/name sizes and maximum number of stats are now variable via the ``--max-obj-name-len`` and ``--max-stats`` options. * **tcp proxy**: added :ref:`access logging <v1.5:envoy_api_field_filter.network.TcpProxy.access_log>`. * **tcp proxy**: added :ref:`configurable connect retries <v1.5:envoy_api_field_filter.network.TcpProxy.max_connect_attempts>`. * **tcp proxy**: enable use of :ref:`outlier detector <v1.5:arch_overview_outlier_detection>`. * **tls**: added :ref:`SNI support <v1.5:faq_how_to_setup_sni>`. * **tls**: added support for specifying :ref:`TLS session ticket keys <v1.5:envoy_api_field_DownstreamTlsContext.session_ticket_keys>`. * **tls**: allow configuration of the :ref:`min <v1.5:envoy_api_field_TlsParameters.tls_minimum_protocol_version>` and :ref:`max <v1.5:envoy_api_field_TlsParameters.tls_minimum_protocol_version>` TLS protocol versions. * **tracing**: added :ref:`custom trace span decorators <v1.5:envoy_api_field_Route.decorator>`. Deprecated ---------- * **outlier_detection**: The outlier detection ``ejections_consecutive_5xx`` stats counter has been deprecated in favour of ``ejections_detected_consecutive_5xx`` and ``ejections_enforced_consecutive_5xx``. * **outlier_detection**: The outlier detection ``ejections_success_rate`` stats counter has been deprecated in favour of ``ejections_detected_success_rate`` and ``ejections_enforced_success_rate``. * **outlier_detection**: The outlier detection ``ejections_total`` stats counter has been deprecated and not replaced. Monitor the individual ``ejections_detected_*`` counters for the detectors of interest, or ``ejections_enforced_total`` for the total number of ejections that actually occurred.
