We wanted to let everyone know of a change to the ItemID structure. This is significant if you are storing the ItemID along with your file information. This ID was improved to make sure it will always be Unique across an application. Since the change will affect existing item ID's we suggest that if you are already storing the Item ID you update your database with the new value returned from GetPathInfo.
Please let us know if you have a large number of Item IDs stored or if you will have any trouble with this change. We will work with you through the transition. We will be making the change on the next release date that is targeted for next week.
