the files became smaller.
Update jQuery files

Demo theme: v1.10.2 -> v1.11.1
Backend: v2.0.3 -> v2.1.1
Furthermore I renamed the jquery-2.0.3.min.js file because of easy to
update jQuery in future.
Permit to display checkBoxes with config file

Can be used for those wanting to make a deletable only list.
Extend query on relation behavior

From a relation behavior config file like this

status:
     label: Status
     list: @/plugins/path/to/your/relation/config/columns.yaml
     emptyMessage: backend::lang.list.no_records

You can extend the list query with this method :

relationExtendQuery($query, $field, $manageMode)
{
     if ($field == 'status') $query->where('thing', '=', $this->thing);
}
