+#### Breaking changes
+
+- The configuration format for ingresses in values.yaml has changed. 
+Previously, all ingresses accepted an array of hostnames, and would create
+ingress rules for each. Ingress configuration for services other than the proxy
+now accepts a single hostname, which allows simpler TLS configuration and
+automatic population of `admin_api_uri` and similar settings. Configuration for
+the proxy ingress is unchanged, but its documentation now accurately reflects
+the TLS configuration needed.
