Has SAP has changed the way licenses are issued?

Hi Everyone;

   I was just informed by my client (Public Works Government Services Canada) that SAP has told them this week that ...

"for two maintenance releases within the same major version that we require two licenses on the same PC; one for 12.1 and another for 12.5".

  My understanding was that a PB 12.5.x .LIC file will also activate a PB 12.x IDE as well on the same PC. In fact, that has been the case in previous years with various versions of PB from Sybase.

Has SAP changed (or are they changing) the way the old Sybase Sysam licenses work?

Regards ... Chris
