This is a feature release with a dedicated support for Spock framework and JUnit4 Parameterized Tests.
Please note that Clover-for-IDEA plug-in does not support Groovy in the IDE (see the Supported Platforms page), so you'll have to use Clover's Ant, Maven or Grails plug-in in order to instrument Spock tests.
