SAS AppDev Studio

A SAS AppDev Studio project must match the maintenance level of the SAS 9.2 installation on which it runs.
If you apply the third maintenance release for SAS 9.2, you must upgrade SAS AppDev Studio to its second maintenance release (which has a product release number of 3.4_M2). This release of SAS AppDev Studio enables you to create SAS projects for, and upgrade projects to, the third maintenance release of SAS 9.2.
Apply the second maintenance release for SAS AppDev Studio (3.4_M2) only if you will be developing SAS projects for SAS 9.2 installations that have applied the third maintenance release.
