Incompatible Behavior Changes¶

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

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

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

zipkin: fix timestamp serializaiton in annotations. A prior bug fix exposed an issue with timestamps being serialized as strings.

Normally occurs at the end of the deprecation period

tls: removed envoy.reloadable_features.tls_use_io_handle_bio runtime guard and legacy code path.

http: added the ability to unescape slash sequences in the path. Requests with unescaped slashes can be proxied, rejected or redirected to the new unescaped path. By default this feature is disabled. The default behavior can be overridden through http_connection_manager.path_with_escaped_slashes_action runtime variable. This action can be selectively enabled for a portion of requests by setting the http_connection_manager.path_with_escaped_slashes_action_sampling runtime variable.
