 #### Features
 
-- `pathMatching.ingress/pathMatching.egress` users can specify paths for ingress and egress path matching.
+- `pathMatching` where users can specify paths for path matching.
 
 The path matching will use the same patterns as the Go standard library (see https://pkg.go.dev/net/http#hdr-Patterns), ensuring reliable and well-supported path matching.
