Interim Product Modifications (IPMs)

Frequently, changes in SQL-related products are introduced individually and separately

from software releases involving the entire product set. These asynchronous

introductions are called interim product modifications or IPMs. An IPM does not have a

distinguishable identifier visible to customers.

An IPM is usually introduced for one of two reasons: to correct defects or to make

minor changes in a product. New features with varying degrees of importance can be

introduced individually in IPMs. However, major overall changes in a product are never

introduced in an IPM, and the release of an IPM never changes a product number or a

version number.

If a significant number of individual new features are released in a single IPM, they can

subsequently result in the introduction of a new version of SQL/MP. To allow for this

possibility, version 300 and all subsequent versions of SQL/MP have three-digit version

numbers. (Versions 1 and 2 are not directly associated with any IPM. For backward

compatibility, version numbers 1 and 2 continue to have single-digit version numbers.)

The three-digit version numbers assigned to the SQL/MP software are not necessarily

consecutive. For example, if the current version of SQL/MP is version 315, the next
