There is an incoming e-mail message from SagePay starting with:
Have you upgraded to Version 3? In order for you to continue processing payments without any interruption to your service, you must upgrade to Sage Pay Version 3. The deadline for upgrading is 4 months away. If you do not upgrade by 31st July 2015 then you will not be able to process payments and all support for your current version of Sage Pay will be discontinued.
What should be done to avoid SagePay service interrupt?
The issue has been reported to the Maintenance team as PBAS-29938.
Support of Sage Pay Version 3 will be included in an upcoming OBAS release.
As a workaround for current OBAS versions, please set VPS Version to 3.00 in the SagePay plug-in configuration.
