---------------

1.7.0
=====
* Added :ref:`weighted round robin
  <arch_overview_load_balancing_types_round_robin>` support. The round robin
  scheduler now respects endpoint weights and also has improved fidelity across
  picks.
* access log: ability to format START_TIME
* admin: added ``/stats/prometheus`` as an alternative endpoint for getting stats in prometheus format.
* logger: all :ref:`logging levels <operations_admin_interface_logging>` can be configured
  at run-time: trace debug info warning error critical.

1.6.0
=====

* access log: added DOWNSTREAM_REMOTE_ADDRESS, DOWNSTREAM_REMOTE_ADDRESS_WITHOUT_PORT, and
  DOWNSTREAM_LOCAL_ADDRESS :ref:`access log formatters <config_access_log_format>`.
  DOWNSTREAM_ADDRESS access log formatter has been deprecated.
* access log: added less than or equal (LE) :ref:`comparison filter
  <envoy_api_msg_config.filter.accesslog.v2.ComparisonFilter>`.
* access log: added configuration to :ref:`runtime filter
  <envoy_api_msg_config.filter.accesslog.v2.RuntimeFilter>` to set default sampling rate, divisor,<commit_msg>Release note related to envoy #2787 (#567)<commit_after>Version history

* logger: all :ref:`logging levels <operations_admin_interface_logging>` can be configured
  at run-time: trace debug info warning error critical.
* tracing: the sampling decision is now delegated to the tracers, allowing the tracer to decide when and if
  to use it. For example, if the :ref:`x-b3-sampled <config_http_conn_man_headers_x-b3-sampled>` header
  is supplied with the client request, its value will override any sampling decision made by the Envoy proxy.
