This chapter summarizes the new features available in SAS/ETS^® 12.1 software.

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 is changing with this release. This new numbering scheme will be maintained when new versions of Base SAS and SAS/ETS ship at the same time. For example, when Base SAS 9.4 is released, SAS/ETS 13.1 will be released.
