History Functions

The history function allows you to view historical field values for Jira fields and use them in formulas. To show the history of a field, use the following format: <fieldName>History

Example:

statusHistory → returns a list of all the status changes that have occurred for an issue

History data is currently available for the following fields:

Status
Story Points
Parent
Date fields
Time estimate fields
Custom numeric fields

Narrowing the History

To narrow the history, use the History function along with Array functions.

Example:

statusHistory.LAST() → returns the last status the issue was in

Display a Field Value at a Specific Time

The following formula allows you to display the value in a specified field at a specific time.

WITH  HISTORICAL_VALUE(field, fieldHistory, date) = 
       IF fieldHistory.IS_EMPTY() AND field : field 
       ELSE fieldHistory.FILTER($.time <= date).toText :
HISTORICAL_VALUE(duedate, duedateHistory, datetime("15/May/18 6:24 PM"))

To customize this formula:

Replace the duedate and duedateHistory with another field
Replace the date and time
