Which version of Drush should I install? Drush 6 works great of corse on a Drupal 6 website, but will I have all of the Drush 6 features when working on a Drupal 7 website? Should I use Drush 7 when working on a drupal 7 website?

I found this post that says you can switch between the two version easily, is this correct?

switch to drush6 command:
composer global require drush/drush:6.*

switch to drush7 command:
composer global require drush/drush:dev-master
Always, always read the docs. Right at the bottom of the first page you'll find this:



Which removes any ambiguity.
