Drush instance has a 7.x-1.1 release! The Drush make-powered framework for building Drupal sites has undergone a fair bit of testing since its initial release and the new tag includes:
- Backwards-compatibility for Drush make <5.9.
- Forwards-compatibility for Drush 7.x!
- Instructions for using Composer rather than PEAR to get PHPUnit for testing, as recommended by the project.
Thanks to Johan and anyone else at Torchbox who helped test. You should download Drush instance now, and start actively developing your Drupal sites with an intelligent, make-powered workflow.
