  *  0-18 used to be the SVN revision, now just last revision before switch to git
  *
  * The 19th bit is there so the development/betas/alpha, etc. leading to a
  * final release will always have a lower version number than the released
  * version, thus making comparisons on specific revisions easy.
+ *
+ * The + 16 for the major version is because we went from 1.11.0 to 12.0, dropping
+ * the "patch" part of the version. To make sure "1.11.0" is smaller than "12.0", we
+ * have to adjust the major by 16.
