DEPRECATED

As of release 1.3.0, Envoy will follow a Breaking Change Policy.

The following features have been DEPRECATED and will be removed in the specified release cycle.

Version 1.4.0

  • Config option statsd_local_udp_port has been deprecated and has been replaced with statsd_udp_ip_address.
  • HttpFilterConfigFactory filter API has been deprecated in favor of NamedHttpFilterConfigFactory.
  • Config option http_codec_options has been deprecated and has been replaced with http2_settings.
  • The following log macros have been deprecated: log_trace, log_debug, conn_log, conn_log_info, conn_log_debug, conn_log_trace, stream_log, stream_log_info, stream_log_debug, stream_log_trace. For replacements, please see logger.h.
  • The connectionId() and ssl() callbacks of StreamFilterCallbacks have been deprecated and replaced with a more general connection() callback, which, when not returning a nullptr, can be used to get the connection id and SSL connection from the returned Connection object pointer.
  • The protobuf stub gRPC support via Grpc::RpcChannelImpl is now replaced with Grpc::AsyncClientImpl. This no longer uses protoc generated stubs but instead utilizes C++ template generation of the RPC stubs. Grpc::AsyncClientImpl supports streaming, in addition to the previous unary, RPCs.
  • The direction of network and HTTP filters in the configuration will be ignored from 1.4.0 and later removed from the configuration in the v2 APIs. Filter direction is now implied at the C++ type level. The type() methods on the NamedNetworkFilterConfigFactory and NamedHttpFilterConfigFactory intefaces have been removed to reflect this.
