Forms 3.1 uses a plugin-approach by populating the appropriate exporter based on mimeType each exporter provides.
To use the new DataExporter, use the Forms.UI package, then subclass DataExporterBase. A new Item is added to the drop-down list in View Form Submission.
Beta flag has been removed.
The new Forms marketing automation connector lets you use the Episerver marketing automation connectors with Episerver Forms 3.
To use Episerver Forms with your existing installation of a marketing automation connector, upgrade to the latest version of that connector and install the Forms marketing automation connector. See also Configuring the Forms marketing automation connector.
