Backlog Item custom statuses are newly introduced in 5.1, but are not exposed in this version of the API for backward compatibility.

A number of existing operations result in a change in a Backlog Item’s status. When this happens, the default status will be chosen automatically.

• moveBacklogItemIntoSprint will set the item to the default In Progress status.
• updateBacklogItem with a completedDate will set the item to the default Done status.

• The WSO suffix is removed from names of the types
• The field BacklogItem.backlogItemId is changed to id
• The field BacklogItem.name replaced title
• The Budget.productId field replaces product
• The DashboardReleaseStatistics.hasUnestimatedItems field replaces unestimatedItemsFlag
• Estimate replaces BacklogItemEstimateWSO and TaskEstimateWSO
• The field Impediment.description replaces detail
• The field Impediment.reporter replaces teamMember
• The field Impediment.lastModifiedDate replaces lastModDate
• Product adds the programIds field to keep track of the programs products are included in
• Program adds the productIds field to keep track of the products included
• The field Release.name replaces title
• The field Release.endDate replaces releaseDate
• Added the field Sprint.nonWorkingDays
• The field Task.name replaces title
• The field Task.currentEstimate replaces estimatedHours
• The field Task.taskBoardStatusRank is removed
• The field TaskHoursSpent.pointPerson replaces userName
• The field TaskHoursSpent.date replaces dateLong
• Added the field User.email

• Wherever possible, the methods in the SOAP interface are taking ID's of the objects instead of the actual objects in order to reduce network traffic.
• Java users: the API is using Lists instead of arrays.
