Family fun
IBM has three different mainstream Db2 releases in the family which shares basically nothing.
Db2 for z/OS (announced here)
Db2 for IBM i (does not have a version in the normal sense as it is integrated in the OS)
DB2 for LUW (Linux/Unix/Windows)
So the question when other family members reach version 13 does not mean anything much for the included functionality.
