 **Notes:**
 
   - Prior to Vagrant 1.7.3, the `ansible_ssh_private_key_file` variable was not set in generated inventory, but passed as command line argument to `ansible-playbook` command.
-  - The generation of group variables blocks (e.g. `[group1:vars]`) are intentionally not supported, as it is [not recommended to store group variables in the main inventory file](http://docs.ansible.com/intro_inventory.html#splitting-out-host-and-group-specific-data). A good practice is to store these group (or host) variables in `YAML` files stored in `group_vars/` or `host_vars/` directories in the playbook (or inventory) directory.
+  - The generation of group variables blocks (e.g. `[group1:vars]`) is only possible since Vagrant ???. Note however that setting variables directly in the inventory is not the [preferred practice in Ansible](http://docs.ansible.com/intro_inventory.html#splitting-out-host-and-group-specific-data). If possible, group (or host) variables should be set in `YAML` files stored in the `group_vars/` or `host_vars/` directories in the playbook (or inventory) directory instead.
   - Unmanaged machines and undefined groups are not added to the inventory, to avoid useless Ansible errors (e.g. *unreachable host* or *undefined child group*)
