To work correctly, a SAS AppDev Studio
4.4 project must match the maintenance level of the SAS 9.4 installation
on which it is run. You need to apply a maintenance update to SAS
AppDev Studio only if you are developing SAS projects for SAS 9.4
installations that have also had maintenance applied. The first maintenance
release for SAS AppDev Studio 4.4 requires the first maintenance release
for SAS 9.4.
