I got back to work this year to find that over the break SAP had release Data Services 4.1 Service Pack 3. This contains a lot of fixes, especially if you are a Salesforce.com user.
I think you will need access to the sap portal to view it, but the release notes are here:
DS 4.1 SP3
Now to shake of the Holiday cobwebs and get cracking with 2014 !
