Reports the minor version number of the Check Point software, refining the major version reported by fwVerMajor. This level of detail distinguishes gateways that are nominally on the same major release but actually running different feature sets or fix levels, relevant when a specific fix or feature only ships starting at a particular minor version. Example: two gateways sharing the same fwVerMajor but differing fwVerMinor values means only one of them has whatever feature or fix was introduced in the later minor release.
