Due to the linear nature of time, software must exist before other software can depend on it. A shared component must be released before software can be ported. In this way, change flows through code like light or sound through their own mediums. This is the speed of compatibility. Consequently, the version that is compatible tends to be older as it becomes more indirect. An app that uses a component directly may need a different release than one that uses it indirectly https://gordonmessmer.codeberg.page/dev-blog/images/png/select-deps-branch-time.drawio.png
