Upgrade SAP Information Steward 4.2 from SP05 to SP06 or SP07.

Hi Team,

We are currently using SAP Information Steward 4.2 SP05. As part of regular upgrade to keep systems in sync, we are planning to upgrade to SP06. But I did not see much beneficial to update with SP06. I understand SP07 is going to release in May 2016. But I did not get any information related to the features and release notes.

Could someone advise is it good to upgrade SP06 now or is it worth to wait till SP07 releases?

Thanks

Venky
