 ### Added
 
 - Add the new `go.opentelemetry.io/contrib/instrgen` package to provide auto-generated source code instrumentation. (#3068, #3108)
+- Add client metric support to `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp`. (#4707)
 - Add peer attributes to spans recorded by `NewClientHandler`, `NewServerHandler` in `go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc`. (#4873)
 
+### Deprecated
+
+- The `RequestCount`, `RequestContentLength`, `ResponseContentLength`, `ServerLatency` constants in `go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp` are deprecated. (#4707)
+
 ### Fixed
 
 - Do not panic in `go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc` if `MeterProvider` returns a `nil` instrument. (#4875)
