Feature Set Reference
This page lists every feature available in each Feature Set, why you would enable it, and the features it depends on. Use it to decide what to turn on and to understand what gets pulled in automatically.
Prerequisites auto-enable. When you enable a feature, every feature in its Prerequisites column is enabled for you if not already present. The chain is transitive — a prerequisite’s own prerequisites are pulled in too.
