Updating from v.3.0 Stable to v.3.1 RC5.5 we have had to slightly modify our forms. Here is what we have done.

1. Backup all your forms, since v.3.0 has no auto update feature.
2. Uninstall the old version and install the new one.
3. Restore your forms and change their names if necessary. We encountered thatif you have dashes in the name they should be replaced with underscore. Otherwise your form will not be recognized by its name.
4. In the checkbox fields, in the "input" element check the attributes: "class" (if it is a required field), "id" and "name", and in the "for" attribute - the "label" element.
5. In Dropdown field clear the "value" attribute for the first option, if it is a "Please, select" notion. Otherwise the form will mark this field as "selected" and will not validate it properly.
6. Close all the "input" and "br" elements with forward slash (/).
