I just released Test Kitchen v1.0.0.beta.4. Release notes. Full diff.
This includes a number of important bug fixes, but the most notable ones are:
- Removing celluloid (TK now uses pure Ruby threads)
- Executing busser suites in their own sandboxes to prevent gem conflicts
- Obeying a chefignore (if present) to determine which files are copied
