 ==== Using Spock to Test Spring Boot Applications
-Spock 2.x can be used to test a Spring Boot application.
-To do so, add a dependency on Spock's `spock-spring` module to your application's build.
+Spock 2.2 or later can be used to test a Spring Boot application.
+To do so, add a dependency on a `-groovy-4.0` version of Spock's `spock-spring` module to your application's build.
 `spock-spring` integrates Spring's test framework into Spock.
