FYI for any users of envoy.deprecated_features overrides

[Alyssa (Rzeszutek) Wilk]

If you have runtime configuration to allow unsupported features, please be aware that the keys to allow use of runtime features changed with https://github.com/envoyproxy/envoy/pull/9591

The old way to allow fatal-by-defaults was
envoy.deprecated_features:proto_file.proto:field_name
the new way is
envoy.deprecated_features:full.namespace.field_name

If you're updating your configs to the latest and greatest as you go, you can just ignore this and carry on :-)

cheers,

Alyssa
