Then call these whenever you want (in these examples the user has launched a bunch of previous versions, and this is the first time he's launched the new version 1.0.11):

vt.isFirstLaunchEver;        // false
vt.isFirstLaunchForVersion;  // true
vt.isFirstLaunchForBuild;    // true

vt.currentVersion;           // 1.0.11
vt.previousVersion;          // 1.0.10
vt.firstInstalledVersion;    // 1.0.0
vt.versionHistory;           // [ 1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.10, 1.0.11 ]

vt.currentBuild;             // 18
vt.previousBuild;            // 15
vt.firstInstalledBuild;      // 1
vt.buildHistory;             // [ 1, 2, 3, 4, 5, 8, 9, 10, 11, 13, 15, 18 ]
