HelloWorks Release 52

- Secure Sender role: the Sender role can now only access the transaction they sent, significantly improving all participant data's security & privacy.

- Error notification: when an instance hard failed (usually caused by improperly-created form through Code editor), users will be informed via:

• Email: an email containing instance GUID and participant email to help users quickly pinpoint the instance/transaction, fix the underlying issue, and resend to the participant.
• API: allow failed instances to return with the Workflow Completion Callback with the status set as error.

User experience improvements

• Merge field: Users can now preview merge fields in the Editor’s test tab.
  
• Display Text component: When a Signature component is created, and there is no Display Text component in the form, one will be automatically created and highlighted. This guidance is aimed to prevent users from sending forms with just the Signature component.
