This can be accessed through the ``%DOWNSTREAM_WIRE_BYTES_SENT%``, ``%DOWNSTREAM_WIRE_BYTES_RECEIVED%``, ``%UPSTREAM_WIRE_BYTES_SENT%``, and ``%UPSTREAM_WIRE_BYTES_RECEIVED%`` access_log command operatrors. -* access_log: make consistent access_log format fields ``%(DOWN|DIRECT_DOWN|UP)STREAM_(LOCAL|REMOTE)_*%`` to provide all combinations of local & remote addresses for upstream & downstream connections. -* admin: :http:post:`/logging` now accepts ``/logging?paths=name1:level1,name2:level2,...`` to change multiple log levels at once. -* cluster: added support for per host limits in :ref:`circuit breakers settings `. Currently only :ref:`max_connections ` is supported. -* cluster: added support to restore original destination address from any desired header via setting :ref:`http_header_name `. -* cluster: support :ref:`override host status restriction `. -* config: added new file based xDS configuration via :ref:`path_config_source `. - :ref:`watched_directory ` can - be used to setup an independent watch for when to reload the file path, for example when using - Kubernetes ConfigMaps to deliver configuration. See the linked documentation for more information. -* config: added new :ref:`custom config validators ` to dynamically verify config updates. -* cors: add dynamic support for headers ``access-control-allow-methods`` and ``access-control-allow-headers`` in cors. -* dns: added :ref:`dns_min_refresh_rate ` - to the DNS cache implementation to configure the minimum DNS refresh rate, regardless of returned - TTL. This was previously hard coded to 5s and defaults to 5s if unset. * ext_proc: added support for per-route :ref:`grpc_service `. -* http: added random_value_specifier in :ref:`weighted_clusters ` to allow random value to be specified from configuration proto. -* http: added request_mirror_policies to higher levels (i.e., :ref:`request_mirror_policies ` in :ref:`RouteConfiguration ` and :ref:`request_mirror_policies ` in :ref:`VirtualHost `) which applies to :ref:`request_mirror_policies ` in all routes underneath without configured mirror policies. -* http: added support for :ref:`cidr_ranges ` for configuring list of CIDR ranges that are considered internal. -* http: added support for :ref:`proxy_status_config ` for configuring `Proxy-Status `_ HTTP response header fields. -* http: make consistent custom header format fields ``%(DOWN|DIRECT_DOWN|UP)STREAM_(LOCAL|REMOTE)_*%`` to provide all combinations of local & remote addresses for upstream & downstream connections. -* http2: adds the new runtime feature ``envoy.reloadable_features.http2_use_oghttp2``, disabled by default, that guards use of a new HTTP/2 implementation. -* http2: re-enabled the HTTP/2 wrapper API. This should be a transparent change that does not affect functionality. Any behavior changes can be reverted by setting the ``envoy.reloadable_features.http2_new_codec_wrapper`` runtime feature to false. -* http3: add :ref:`enable_early_data ` to turn on/off downstream early data support. -* http3: downstream HTTP/3 support is now GA! Upstream HTTP/3 also GA for specific deployments. See :ref:`here ` for details. -* http3: supports upstream HTTP/3 retries. Automatically retry `0-RTT safe requests `_ if they are rejected because they are sent `too early `_. And automatically retry 0-RTT safe requests if connect attempt fails later on and the cluster is configured with TCP fallback. And add retry on ``http3-post-connect-failure`` policy which allows retry of failed HTTP/3 requests with TCP fallback even after handshake if the cluster is configured with TCP fallback. This feature is guarded by ``envoy.reloadable_features.conn_pool_new_stream_with_early_data_and_http3``. -* local_ratelimit: added support for sharing the rate limiter between multiple network filter chains or listeners via :ref:`share_key `. -* local_ratelimit: added support for X-RateLimit-* headers as defined in `draft RFC `_. -* matching: the matching API can now express a match tree that will always match by omitting a matcher at the top level. -* outlier_detection: :ref:`max_ejection_time_jitter` configuration added to allow adding a random value to the ejection time to prevent 'thundering herd' scenarios. Defaults to 0 so as to not break or change the behavior of existing deployments. -* redis: support for hostnames returned in ``cluster_slots`` response is now available. -* router: added a path-separated prefix matcher, to make route creation more efficient. :ref:`path_separated_prefix `. -* schema_validator_tool: added ``bootstrap`` checking to the - :ref:`schema validator check tool `. -* schema_validator_tool: added ``--fail-on-deprecated`` and ``--fail-on-wip`` to the - :ref:`schema validator check tool ` to allow failing - the check if either deprecated or work-in-progress fields are used. -* schema_validator_tool: fixed linking of all extensions into the - :ref:`schema validator check tool ` so that all typed - configurations can be properly verified. -* schema_validator_tool: the - :ref:`schema validator check tool ` will now recurse - into all sub messages, including Any messages, and perform full validation (deprecation, - work-in-progress, PGV, etc.). Previously only top-level messages were fully validated. -* stats: histogram_buckets query parameter added to stats endpoint to change histogram output to show buckets. -* tap: added support for buffering an arbitrary number of tapped traces before returning to the client via a new :ref:`buffered admin sink `. -* tcp_proxy: added support for on demand cluster. If the :ref:`on_demand ` is set and the destination cluster is not present, a delta CDS request will be sent and the tcp proxy flow will be resumed after that cds response. -* thrift: add support for connection draining. This can be enabled by setting the runtime guard ``envoy.reloadable_features.thrift_connection_draining`` to true. -* thrift: added support for dynamic routing through aggregated discovery service. -* tls: add support for tls key log :ref:`key_log`. -* tools: the project now ships a :ref:`tools docker image ` which contains tools - useful in support systems such as CI, CD, etc. The - :ref:`schema validator check tool ` has been added - to the tools image. -* udp_proxy: added :ref:`matcher ` to support matching and routing to different clusters. -* udp_proxy: added support for :ref:`access_log `.
