New-function APARs for Db2 12

Db2 12 introduces the continuous delivery of new capabilities in a single service stream. Many APARs in Db2 12 deliver deactivated functional code to support future function levels. However, some introduce their enhancements immediately, at any Db2 function level.

The following table summarizes the new-function APARs for Db2 12 from newest to oldest, including the APARs that enable activation of Db2 12 function levels. However, it does not include APARs that stage code for future Db2 12 function levels, "bug fixes," or other maintenance APARs.
