Understanding Maintenance Release Numbers

After you install a maintenance release, the product release number for updated products changes to include maintenance-specific identification, such as M1. This maintenance number is incremented by one for each maintenance release of that product. However, a maintenance release (such as the second or third maintenance release for SAS 9.2) might not contain updates for all SAS products. Therefore, maintenance numbers can differ across SAS products. To determine the maintenance numbers for products at your site, generate a deployment registry report. For more information, see Determining the Product Release Numbers for Products at Your Site.
The following table shows some of the maintenance release numbers in the third maintenance release for SAS 9.2:
Examples of Maintenance Release Numbers for SAS Products
Product Name
Release Number
Base SAS
9.21_M3
SAS Data Integration Studio
4.21_M2
SAS Management Console
9.2_M2
SAS Web Report Studio
4.2_M2
As this table shows, most products in the third maintenance release for SAS 9.2 have a maintenance release number of M2. However, Base SAS has a maintenance release number of M3.
The maintenance release numbers are different because there have been three maintenance releases for Base SAS. The first maintenance release did not contain product updates. Instead, it contained localized Help for the SAS Intelligence Platform products.
The second maintenance release for SAS 9.2 did contain product updates. For this maintenance release, the maintenance release number for Base SAS was incremented to M2. However, other products in the table were not delivered in the first maintenance release for SAS 9.2. Because this was the first time that these products were included in a maintenance release, their maintenance release number was M1.
For the third maintenance release, both Base SAS and the other products in the table are being updated. Therefore, all of the maintenance release numbers are incremented by 1. As a result, Base SAS has a maintenance release number of M3, and the other SAS products have a maintenance release number of M2.
