-# Only puppet 3.2.1 - 3.8 support "--parser future" option.
+# Only puppet 3.1.1 - 3.8.7 support "--parser future" option.
 case $(puppet --version) in
-  4*) USE_PUPPET_FUTURE_PARSER="disabled" ;;

The "--parser=future" command-line setting was added in version 3.1.1 (See lib/puppet/version.rb and lib/puppet/defaults.rb).

5*) USE_PUPPET_FUTURE_PARSER="disabled" ;;
