behavior_changes:
# *Changes that are expected to cause an incompatibility if applicable; deployment changes are likely required*

minor_behavior_changes:
# *Changes that may cause incompatibilities for some users, but should not for most*
- area: quic
  change: |
    Access logging is now deferred to the QUIC ack listener, and roundtrip response time is added as a downstream timing metric. New runtime flag ``envoy.reloadable_features.quic_defer_logging_to_ack_listener`` can be used for revert this behavior.
- area: healthcheck
  change: |
    If active HC is enabled and a host is ejected by outlier detection, a successful active health check unejects the host and consider it healthy. This also clears all the outlier detection counters. This behavior change can be reverted by setting ``envoy.reloadable_features_successful_active_health_check_uneject_host`` to ``false``.

bug_fixes:
# *Changes expected to improve the state of the world and are unlikely to have negative effects*
- area: stats
  change: |
    now updating upstream total connection stats as happy eyeballs connections are created.
- area: eds
  change: |
    added ``envoy.reloadable_features.multiplex_eds`` to disable eds multiplexing. Eds multiplexing is enabled by default, so that all subscriptions for the same resource type and management server reuse a single channel/mux.
    When eds multiplexing is disabled each subscription uses a dedicated channel/mux.
- area: router
  change: |
    fixed the bug that custom tags of the route metadata type are not set for upstream spans.

# *Normally occurs at the end of the* :ref:`deprecation period <deprecated>`

    removed ``envoy.reloadable_features.combine_sds_requests`` and legacy code paths.
- area: dns
  change: |
    removed ``envoy.reloadable_features.dns_multiple_addresses`` runtime flag and legacy code paths.
- area: router
  change: |
    removed ``envoy.reloadable_features.get_route_config_factory_by_type`` runtime flag. The flag is no longer needed as the behavior is now the default.
- area: http
  change: |
    removed ``envoy.reloadable_features.http2_delay_keepalive_timeout`` and legacy code paths.
- area: http
  change: |
    removed ``envoy.reloadable_features.local_ratelimit_match_all_descriptors`` and legacy code paths.

new_features:
- area: access_log
  change: |
    enhanced observability into local close for :ref:`%RESPONSE_CODE_DETAILS% <config_http_conn_man_details>`.
- area: tracing
  change: |
    allow :ref:`grpc_service <envoy_v3_api_field_config.trace.v3.OpenTelemetryConfig.grpc_service>` to be optional. This enables a means to disable collection of traces.
- area: upstream
  change: |
    added :ref:`ring hash extension <envoy_v3_api_msg_extensions.load_balancing_policies.ring_hash.v3.RingHash>` to suppport the :ref:`load balancer policy <envoy_v3_api_field_config.cluster.v3.Cluster.load_balancing_policy>`.
- area: upstream
  change: |
    added :ref:`maglev extension <envoy_v3_api_msg_extensions.load_balancing_policies.maglev.v3.Maglev>` to suppport the :ref:`load balancer policy <envoy_v3_api_field_config.cluster.v3.Cluster.load_balancing_policy>`.
- area: router
  change: |
    support route info in upstream access log.
- area: lua
  change: |
    added an new option to the options of lua ``httpCall``. This allows to skip adding ``x-forwarded-for`` by setting ``{["send_xff"] = false}`` as the ``options``.
