 ## Compatibility matrix
 
-The Cucumber Scala major version matches the Cucumber major version.
+Cucumber Scala has a different release cycle than other Cucumber projects that you might use
+(like _cucumber-junit_).
 
-The minor version might differ because Cucumber Scala may add Scala-related features without waiting for a Cucumber minor version.
+As a rule of thumb, you can assume that latest version of Cucumber Scala targets the latest version
+of Cucumber Core projects.
