Serenity 2.2.0 is a major update that adds support for Cucumber 5.5.0 .
Cucumber 5 is a significant new release with many new features. It is not backward-compatible with Cucumber 4 or Cucumber 2,
so from Serenity 2.2.0 onwards, you will also need to upgrade to serenity-cucumber version 2.2.0 or higher.
