:question: What’s the difference between `@Stable` and `@StableMarker` ? :thinking_face::thread:

`@StableMarker` is a meta-annotation, which is added to annotations which indicate a stability of a type. Apps should not use it directly i think. :slightly_smiling_face:

`@StableMarker` is applied to other annotations to indicate that any type annotated with this other annotations is stable.

`@Stable` annotation is in itself annotated with `@StableMarker`

Stability means:

• Calls to equal has the same result of any two instances with the same content
• Composition is aware when public properties change
• All public properties of the annotated type is stable
