 Email sent from the contact forms to the contact(s) for a collection, dataset, or datafile can now optionally be cc'd to a support email address. The support email address can be changed from the default :SystemEmail address to a separate :SupportEmail address. When multiple contacts are listed, the system will now send one email to all contacts (with the optional cc if configured) instead of separate emails to each contact. Contact names with a comma that refer to Organizations will no longer have the name parts reversed in the email greeting. A new protected feedback API has been added. (PR #9186)
