From HDIP v1.3.1.release0, a new versioning system was adopted. Patch numbers are no longer displayed as a suffix to the version number, but are referred to by their build number, e.g. v188.8.131.520. This is designed to help everyone identify which version they are using, and how it relates to every other version. Note that HDIP only notifies users when a new major versions of HDIP is released. To obtain the very latest version of HDIP, you can request a software update at http://www.teledynecetac.com/support/software.
