.. _version_history_1.13.0: 1.13.0 (January 20, 2020) ========================== Changes ------- * **access log**: added ``FILTER_STATE`` :ref:`access log formatters ` and gRPC access logger. * **access log**: added ``HOSTNAME``. * **access log**: added a :ref:`typed JSON logging mode ` to output access logs in JSON format with non-string values. * **access log**: fixed ``UPSTREAM_LOCAL_ADDRESS`` :ref:`access log formatters ` to work for http requests. * **admin**: added the ability to filter :ref:`/config_dump `. * **api**: added ability to specify ``mode`` for :ref:`Pipe `. * **api**: remove all support for v1. * **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 ` 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 ` to send the :ref:`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**: added :ref:`TlsOptions ` to allow TLS configuration overrides. * **health check**: added :ref:`service_name_matcher ` to better compare the service name patterns for health check identity. * **health check**: gRPC health checker sets the gRPC deadline to the configured timeout duration. * **http**: added strict validation that ``CONNECT`` is refused as it is not yet implemented. This can be reversed temporarily by setting the runtime feature ``envoy.reloadable_features.strict_method_validation`` to false. * **http**: added support for http1 trailers. To enable use :ref:`enable_trailers `. * **http**: added the ability to sanitize headers nominated by the Connection header. This new behavior is guarded by ``envoy.reloadable_features.connection_header_sanitization`` which defaults to true. * **http**: blocks unsupported transfer-encodings. Can be reverted temporarily by setting runtime feature ``envoy.reloadable_features.reject_unsupported_transfer_encodings`` to false. * **http**: support :ref:`auto_host_rewrite_header ` in the dynamic forward proxy. * **jwt_authn**: added :ref:`allow_missing ` option that accepts request without token but rejects bad request with bad tokens. * **jwt_authn**: added :ref:`bypass_cors_preflight ` to allow bypassing the CORS preflight request. * **lb_subset_config**: new fallback policy for selectors: :ref:`KEYS_SUBSET `. * **listeners**: added :ref:`reuse_port ` option. * **logger**: added :ref:`--log-format-escaped ` command line option to escape newline characters in application logs. * **ratelimit**: added :ref:`local rate limit ` network filter. * **rbac**: added support for matching all subject alt names instead of first in :ref:`principal_name `. * **redis**: add :ref:`host_degraded_refresh_threshold ` and :ref:`failure_refresh_threshold ` to refresh topology when nodes are degraded or when requests fails. * **redis**: correctly follow MOVE/ASK redirection for mirrored clusters. * **redis**: performance improvement for larger split commands by avoiding string copies. * **router**: added :ref:`auto_sni ` to support setting SNI to transport socket for new upstream connections based on the downstream HTTP host/authority header. * **router**: added :ref:`request_mirror_policies ` to support sending multiple mirrored requests in one route. * **router**: added histograms to show timeout budget usage to the :ref:`cluster stats `. * **router**: added support for :ref:`max_internal_redirects ` for configurable maximum internal redirect hops. * **router**: added support for ``HOSTNAME`` :ref:`header formatter `. * **router**: added support for ``REQ(header-name)`` :ref:`header formatter `. * **router**: added support for percentage-based :ref:`retry budgets `. * **router**: allow using a :ref:`query parameter ` for HTTP consistent hashing. * **router**: exposed ``DOWNSTREAM_REMOTE_ADDRESS`` as custom HTTP request/response headers. * **router**: skip the Location header when the response code is not a 201 or a 3xx. * **router check tool**: added support for testing and marking coverage for routes of runtime fraction 0. * **server**: added :ref:`workers_started ` that indicates whether listeners have been fully initialized on workers. * **server**: added the :option:`--disable-extensions` CLI option, to disable extensions at startup. * **server**: fixed a bug in config validation for configs with runtime layers. * **tcp_proxy**: added :ref:`ClusterWeight.metadata_match `. * **tcp_proxy**: added :ref:`hash_policy `. * **thrift_proxy**: added stats to the router filter. * **thrift_proxy**: added support for cluster header based routing. * **tls**: added support for :ref:`generic string matcher ` for subject alternative names. * **tls**: remove TLS 1.0 and 1.1 from client defaults. * **tracing**: added initial support for AWS X-Ray (local sampling rules only) :ref:`X-Ray Tracing `. * **tracing**: added tags for gRPC request path, authority, content-type and timeout. * **tracing**: added the ability to set custom tags on both the :ref:`HTTP connection manager ` and the :ref:`HTTP route `. * **tracing**: added upstream_address tag. * **udp**: added initial support for :ref:`UDP proxy `. Deprecated ---------- * **certificates**: The ``verify_subject_alt_name`` field in :ref:`Certificate Validation Context ` has been deprecated in favor of the :ref:`match_subject_alt_names ` field. * **health_checker**: The ``service_name`` field in :ref:`HTTP health checker ` has been deprecated in favor of the ``service_name_matcher`` field. * **router**: The ``request_mirror_policy`` field in :ref:`RouteMatch ` has been deprecated in favor of the ``request_mirror_policies`` field. * **tracing**: The ``request_headers_for_tags`` field in :ref:`HTTP connection manager ` has been deprecated in favor of the :ref:`custom_tags ` field. * **xds**: The v2 xDS API is deprecated. It will be supported by Envoy until EOY 2020. See :ref:`api_supported_versions`.
