In the previous exercise, you may have noticed that the app_version column has text values like 1.1.0 or 1.1.1. What do these 3 numbers mean? Why not have versions like v1 or v2?
Such notation with three numbers is called semantic versioning. It’s used a lot in software development to version software libraries and projects.
Semantic versioning follows this pattern: MAJOR.MINOR.PATCH.
- MAJOR version changes when you make incompatible API changes. When Bindle completely rebuilds their app they’ll bump major version to 2.0.0.
