 ### OpenTelemetry Integration
 
-There are also optional features `tracing-otel-26`, `tracing-otel-27`, and `tracing-otel-28`
+There are also optional features `tracing-otel-26` through `tracing-otel-30`
 that pair with the `axum-service` feature to ensure that any outgoing requests for credentials
 that take place in the context of an incoming web request also include the proper OpenTelemetry
