This chapter summarizes the new features available in SAS/ETS 12.1 and SAS/ETS 12.3.

If you have used SAS/ETS procedures in the past, you can review this chapter to learn about the new features that have been added. When you see a new feature that might be useful for your work, turn to the appropriate chapter to read about the feature in detail.

In previous years, SAS/ETS software was updated only with new releases of Base SAS software, but this is no longer the case. This means that SAS/ETS software can be released to customers when enhancements are ready, and the goal is to update SAS/ETS every 12 to 18 months. To mark this newfound independence, the release numbering scheme for SAS/ETS changed starting with SAS/ETS 12.1. This new numbering scheme will be maintained when new versions of Base SAS and SAS/ETS are shipped at the same time.

SAS/ETS 12.3 is a maintenance release. No new features have been added. The information in this book applies to SAS/ETS 12.1 and SAS/ETS 12.3.
