6.0.0

The highlight of Drush 6 is the new outputformat system. You can now request Drush output in easily parsed formats like json, csv, ini, etc. See https://github.com/drush-ops/drush/blob/8.x-6.x/docs/output-formats.html

Note: if you are using Drupal 8, you should stick with a frequently updated clone of master branch. Drush 6 supports Drupal 6+7 but not Drupal 8.
