This appendix introduced you to the main features included in Kettle 4.0. All the explanations and exercises in this book have been developed, explained, and tested in the latest stable version 3.2. However, as the new version of the product includes mainly Enterprise or advanced features, working with Kettle 4.0 Community Edition is not so different from working with Kettle 3.2. You can try all the examples and exercises in the book in Kettle 4.0 if you want to. You shouldn't have any difficulties.
