Aspose.Tasks Cloud 18.9 Release Notes

Important Changes and New Features

1. Duration type was added:



  "TimeSpan": "10:00:00",

  "TimeUnit": "Hour"


2. [Breaking] Changes in ExtendedAttribute type (used in Task.ExtendedAttributes, Resource.ExtendedAttributes, ResourceAssignment.ExtendedAttributes collections):

  • ‘DurationFormat’ field was removed
  • ‘Value’ field was removed
  • ‘AttributeType’ field was added
  • Following fields were added: ‘DateValue’, ‘DurationValue’, ‘NumericValue’, ‘FlagValue’, ‘TextValue’

The following table shows which field contains the value of extended attribute depending on ExtendedAttribute’s type. Thus in order to get or set the value of a custom field with ‘Date’, ‘Start’ or ‘Finish’ type one should use ‘DateValue’ field.

Extended Attribute type ExtendedAttribute field
Date, Start, Finish DateValue
Duration DurationValue
Flag FlagValue
Number, Cost NumericValue
Text TextValue

"Task" : 



    "ExtendedAttributes": [


        "FieldId": "188743950",

          "TimeSpan": "10:00:00",

          "TimeUnit": "Hour"
