 Version  | 
 Following IBM standards, the term version refers to a generation of a software product that has significant new code or new functionality. Version is a more general term than release. For example, Version 6 includes Release 6.1 and Release 6.2, and is equivalent to Release 6.x.  |

 Release  | 
 Following IBM standards, the term release refers to a program or set of programs which represent a specific revision to the base version of a software product. For example, Release 6.0 is a term that is used to identify the first release of Version 6. Subsequent releases made available under the Version 6 umbrella, such as Release 6.1, will provide additional revisions to the base product.  |

 Modification Level  | 
 Following IBM standards, the term modification level refers to the application of specific program enhancements and error corrections to the release of a software product. For example, Release 6.0.3 is at modification level 3, and Release 6.1.0 is at modification level 0.  |
