This feature removes the previous limitations on the select list column, and now allows you to select all of the columns from the objects you wish to include in the Export API without the previous limitation.  

Previously, with the Data export API, when the number of columns in the select list exceeded the imposed limitation, the error below was provided, this feature removes the limitation that was triggering the generation this error.

API Error with statusCode: 400 and response: {"status":409,"title":"Conflict","detail":"The request could not be completed due to a conflict with the current state of the resource.","o:errorDetails":[{"title":"SQLException","o:errorCode":"12899","o:errorDetails":[{"title":"OracleDatabaseException"}]}]} 

This feature eliminates the select list character limitations, which limited the number of columns that could be specified in the select list.  With this feature you are now able to list all of the columns you would like to include in your Data Export, without hitting the previous character limit.
