February 28, 2020 release notes
If you need to import records from a development tool, you can now choose from an existing integration or create a new integration from the same page.
An issue was causing records updated by CSV import to change to the default assignee if the import included an invalid Assigned to value for that record. Now, a CSV import will not update an existing record’s assignee in that situation.
When an idea was promoted to an initiative, master feature, or feature, an issue was preventing custom fields from being included on the promoted record.
