Each What's changed section provides information about changes to existing functionality from previous versions of Db2.

Modification packs and fix packs

Db2 uses a four part product signature that includes both Modification Pack values (Mod Pack) and Fix Pack values.

The Db2 four part product signature is of the format VV.RR.MM.FF where:
  • VV Is the Version number.
  • RR Is the Release number.
  • MM Is the Modification number.
  • FF Is the Fix Pack number.

The product signature format follows the Maintenance Delivery Vehicle standard that is used throughout the IBM® product lines. For more information, see Maintenance Stream Delivery Vehicle terminology. A Modification number, also referred to as a Mod Pack, is used to indicate new significant features. Subsequent updates for Db2 12.1 now follow this product signature standard.
