Under this scheme, version numbers and the way they change convey meaning about the underlying code and what has been modified from one version to the next.
When we introduce a new version of Natural Earth, you can tell by the version number how much effort you will need to extend to integrate the data with your map implementation.
* Bug fixes Z: can simply use the new data files, replacing your old files.
* Minor version Y: limited integration challenges, primarily around leveraging new content.
* Major version X: significatnt integration challenges, either around changed file strucutre, field layout, field values like `FeatureCla` used in symbolizing data, or significant new additions or significant changes to existing themes.
