We have a number of add-ons for Gravity Forms that are in the process of being updated to ensure compatibility with version 1.9.
In the latest version of Gravity Forms, Name and Address advanced fields have changed in the way that they are setup. In the forms editor there is now more flexibility over which of the parts of these fields you would like to show to a user.
Users of our add-ons for Zoho CRM, Trello and Help Scout may have some problems if updating to version 1.9.x before we release updates to our add-ons. If you are using these advanced fields we encourage you to test your setup with 1.9 before committing to your live website.
Our development team is currently working on updates that will ensure compatibility going forward. Keep an eye on our blog here for details of these updates. You can choose to subscribe to plugin updates here to be notified via eMail.
