1.13.0 (January 20, 2020)

Changes

  • access log: added FILTER_STATE access log formatters and gRPC access logger.

  • admin: added the ability to filter /config_dump.

  • access log: added a typed JSON logging mode to output access logs in JSON format with non-string values

  • access log: fixed UPSTREAM_LOCAL_ADDRESS access log formatters to work for http requests

  • access log: added HOSTNAME.

  • api: remove all support for v1

  • api: added ability to specify mode for Pipe.

  • 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_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 TlsOptions to allow TLS configuration overrides.

  • health check: added 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. 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 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 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: performance improvement for larger split commands by avoiding string copies.

  • redis: correctly follow MOVE/ASK redirection for mirrored clusters.

  • redis: add host_degraded_refresh_threshold and failure_refresh_threshold to refresh topology when nodes are degraded or when requests fails.

  • router: added histograms to show timeout budget usage to the cluster stats.

  • router check tool: added support for testing and marking coverage for routes of runtime fraction 0.

  • router: added request_mirror_policies to support sending multiple mirrored requests in one route.

  • 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_ADDRESS as custom HTTP request/response headers.

  • router: added support for max_internal_redirects for configurable maximum internal redirect hops.

  • router: skip the Location header when the response code is not a 201 or a 3xx.

  • 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 support for HOSTNAME header formatter.

  • server: added the --disable-extensions CLI option, to disable extensions at startup.

  • server: fixed a bug in config validation for configs with runtime layers.

  • server: added workers_started that indicates whether listeners have been fully initialized on workers.

  • tcp_proxy: added ClusterWeight.metadata_match.

  • tcp_proxy: added hash_policy.

  • thrift_proxy: added support for cluster header based routing.
