Version Changes

Defined Changes In Each Version

A version (i.e., 8.014, etc.) contains bug fixes and sometimes added features. You can update to the latest version regardless of what release (i.e., Pipe2016, Pipe2014, Pipe2012, etc.) you are licensed for, and we recommend that users update when a new version becomes available, and before calling Technical Support, since updating may resolve the issue.

Each Version update is accompanied by a Change Description. In the descriptions, the term “critical fix” means any change which has the potential, however remote, to affect analysis results. The description includes information on specific scenario and simulation types where results may be affected.
