This update uses the new SHAsign calculation that is mandatory for all PostFinance clients who registered for e-payment after October 1, 2010.

Those who registered before, still have an option in their merchant GUI configuration which can be set to "Main parameters only" (http://screencast.com/t/9csrSunKg) which will enforce the old SHAsign calculation.

More details can be found in the advanced technical integration guide for e-commerce v3.0 which can be downloaded from inside the merchant GUI.
