The Project Edit History page, previously only detailing the changes made to the Project State, now provides more information including the Modification, Previous Value, New Value, Date Modified and Modified by.
When the new Project Detailed Auditing option, available under Setup > Work tier within the Audit Trail settings is enabled, changes made to the Project within the Project Details page (General, Options and UDF tabs) can now be tracked and available on the History page to indicate what, when and by whom it was made. For more information on how to enable auditing for project details click here.
Previous values of any changed properties made to the Project Details (General, Options and UDF tabs) can be viewed/verified, as well by whom and how far back the modification was made, should a question/concern arise as a result.
