1.31.0 (Pending)

Incompatible behavior changes

Changes that are expected to cause an incompatibility if applicable; deployment changes are likely required

  • thread_local: Changes the behavior of the SlotImpl class destructor. With this change the destructor can be called on any thread. This behavior can be reverted by setting the runtime flag envoy.reloadable_features.allow_slot_destroy_on_worker_threads to false.

Minor behavior changes

Changes that may cause incompatibilities for some users, but should not for most

  • tracers: Set status code for OpenTelemetry tracers (previously unset).

Bug fixes

Changes expected to improve the state of the world and are unlikely to have negative effects

  • outlier detection: Fixed successful_active_health_check_uneject_host. Before, a failed health check could uneject the host if the FAILED_ACTIVE_HC health flag had not been set.

  • tls: Fix a RELEASE_ASSERT when using auto_sni if the downstream request :authority was longer than 255 characters.

Removed config or runtime

Normally occurs at the end of the deprecation period

  • http: Removed envoy.reloadable_features.lowercase_scheme runtime flag and lagacy code paths.

  • http: Removed envoy.reloadable_features.proxy_status_upstream_request_timeout runtime flag and lagacy code paths.

  • tcp: Removed envoy.reloadable_features.detect_and_raise_rst_tcp_connection runtime flag and legacy code paths.

New features

  • matching: Added Filter State Input for matching http input based on filter state objects.
