Local engine versioning
The version number for the Scan local engine comprises three numbers, X.Y.Z (for example 1.1.2), which follows industry standard versioning:
X: A major version of the Scan local engine.
Typically, this version number changes only when the Scan local engine has significant changes. For example, releasing a new engine that fundamentally changes the core architecture represents a major version change.
Y: A minor version of the Scan local engine.
This version number changes for improvements of core components within the Scan local engine. For example, upgrading an existing engine or updating a supported version of Java that the engine uses represents a minor version change.
Z: A maintenance release of the Scan local engine.
Usually, updates for the Scan local engine occur on a monthly basis, therefore, this version number changes with each monthly release.
