 *  An increment in the major number of the stack implies a large update to
 *  the stack. Such an update could occur due to multiple factors, including
 *  changes to stack to adhere to new version of the specification or
 *  support for new device specializations or in extreme cases a design
 *  overhaul to address future needs.
 *
 *  An update in the major number would signify an update to the application
 *  interface offered by the stack. Update need not necessarily imply a
 *  change in existing interface, it could be additional APIs or events.
 *  When an increment in major number occurs, minor & sub-minor numbers
 *  are reset to zero. In event of minor number reaching 255, the max
 *  permissible number, a change resulting in increment in minor version
 *  number will result in increment in major number.

 *  none of these changes are categorized as causing an increment in minor
 *  number, cause any change in existing interface. It is possible that an
 *  existing functionality is required to be conditionally included; hence
 *  feature flag may be introduced to enable or disable inclusion of the
 *  functionality. Such a change would be categorized under a change resulting
 *  in increment in minor number.
 *  When an increment in minor number occurs, sub-minor number is reset
 *  to zero. In event of sub-minor number reaching 255, the max permissible
 *  number, a change resulting in increment in sub-minor number will result in
 *  increment in minor number.
