SpatialKey is offered principally as a SaaS application, with SpatialKey On-Demand. The software is continuously updated. Typically our development/deployment cycles are six weeks long. As such, we don’t take a formal approach to numbering our releases.
If your organization opted for SpatialKey On-Premise, automatic updates are not possible so the release of SpatialKey that you have is subject to when the last upgrade of the environment was completed.
