1.13.0 (January 20, 2020)¶
Changes¶
- access log: added - FILTER_STATEaccess log formatters and gRPC access logger.
- access log: added - HOSTNAME.
- access log: added a typed JSON logging mode to output access logs in JSON format with non-string values. 
- access log: fixed - UPSTREAM_LOCAL_ADDRESSaccess log formatters to work for http requests.
- admin: added the ability to filter /config_dump. 
- api: added ability to specify - modefor Pipe.
- api: remove all support for v1. 
- api: support for the v3 xDS API added. See Supported API 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 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 configurable ability to send the certificate to the - ext_authzservice.
- fault: fixed an issue where the http fault filter would repeatedly check the percentage of abort/delay when the - x-envoy-downstream-service-clusterheader was included in the request to ensure that the actual percentage of abort/delay matches the configuration of the filter.
- health check: added TlsOptions to allow TLS configuration overrides. 
- health check: added 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 - CONNECTis refused as it is not yet implemented. This can be reversed temporarily by setting the runtime feature- envoy.reloadable_features.strict_method_validationto false.
- http: added support for http1 trailers. To enable use 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_sanitizationwhich defaults to true.
- http: blocks unsupported transfer-encodings. Can be reverted temporarily by setting runtime feature - envoy.reloadable_features.reject_unsupported_transfer_encodingsto false.
- http: support auto_host_rewrite_header in the dynamic forward proxy. 
- jwt_authn: added allow_missing option that accepts request without token but rejects bad request with bad tokens. 
- jwt_authn: added bypass_cors_preflight to allow bypassing the CORS preflight request. 
- lb_subset_config: new fallback policy for selectors: KEYS_SUBSET. 
- listeners: added reuse_port option. 
- logger: added –log-format-escaped command line option to escape newline characters in application logs. 
- ratelimit: added local rate limit network filter. 
- rbac: added support for matching all subject alt names instead of first in principal_name. 
- redis: add host_degraded_refresh_threshold and 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 auto_sni to support setting SNI to transport socket for new upstream connections based on the downstream HTTP host/authority header. 
- router: added request_mirror_policies to support sending multiple mirrored requests in one route. 
- router: added histograms to show timeout budget usage to the cluster stats. 
- router: added support for max_internal_redirects for configurable maximum internal redirect hops. 
- router: added support for - HOSTNAMEheader formatter.
- router: added support for - REQ(header-name)header formatter.
- router: added support for percentage-based retry budgets. 
- router: allow using a query parameter for HTTP consistent hashing. 
- router: exposed - DOWNSTREAM_REMOTE_ADDRESSas 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 workers_started that indicates whether listeners have been fully initialized on workers. 
- server: added the - --disable-extensionsCLI option, to disable extensions at startup.
- server: fixed a bug in config validation for configs with runtime layers. 
- tcp_proxy: added ClusterWeight.metadata_match. 
- tcp_proxy: added hash_policy. 
- thrift_proxy: added stats to the router filter. 
- thrift_proxy: added support for cluster header based routing. 
- tls: added support for 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) 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 HTTP connection manager and the HTTP route. 
- tracing: added upstream_address tag. 
- udp: added initial support for UDP proxy.
