 When using Spring for Apache Kafka in a Spring Boot application, the Apache Kafka dependency versions are determined by Spring Boot's dependency management.
 If you wish to use a different version of `kafka-clients` or `kafka-streams`, and use the embedded kafka broker for testing, you need to override their version used by Spring Boot dependency management; set the `kafka.version` property.
 
-NOTE: Default `kafka-clients` dependencies for Spring Boot 3.1.x and 3.2.x are 3.4.1 and 3.6.2 respectively.
+NOTE: Both Spring Boot 3.5.x and 3.4.x use the `kafka-clients` version 3.8.x and if users need to use 3.9.x client, they have to manually upgrade it using the method below.
 
 Or, to use a different Spring for Apache Kafka version with a supported Spring Boot version, set the `spring-kafka.version` property.
