A version is a software component that you cannot change.

It is like a bound book whose pages you cannot update or replace with new ones.

You create a version from an edition. To create a version of a component that contains other components, you must first create versions of the contained components.

To modify a version, you must create an edition of it, change the edition, and create a version of the updated edition. Note that the old version is still available from the library. To modify methods used by a class contained in an application version, you must create editions of both the application and the class, and then work with the methods in those editions.

Each version has a version name, such as R1.1.

When you ship a software product, all components of the product are versions.

For more information on creating versions, see Creating versions of components.
