New Features
- Added the new
transport_api_versionfield to theextauthsettings. The field determines the API version for theext_authztransport protocol that will be used by Envoy to communicate with the auth server. The currently allowed values areV2andV3, with the former being the default; this was done to maintain compatibility with existing custom auth servers. Note that in order for the external auth server to be able to emit dynamic metadata the field needs to be set toV3. For more info, see thetransport_api_versionfield here. (#4160)
