Ranger annual software maintenance is a paid service allowing the covered licence(s) to receive unlimited software upgrades, bug fixes and technical support.
If the maintenance expires without being renewed, the license is ineligible for upgrades, bug fixes and technical support. When a Ranger license owner requires one of these benefits after maintenance expires, then a new Ranger license with maintenance must be purchased. Renewing annual software maitenance is much less expensive than buying a new license.
Ranger users buy software maintenance in three-year blocks to reduce billing and payment overhead. This helps keep the cost low.
