 owners may petition for its continued maintenance if they want, at which point the component will no
 longer be considered vendor-specific.

+## Versioning
+
+Components are Go modules and as such follow [semantic versioning](https://semver.org/). Go API stability guarantees are covered in the [VERSIONING.md](../VERSIONING.md) document.
+The versioning of the components applies to all signals simultaneously. For a component to be marked as 1.x it MUST be stable for at least one signal.
+
+Even if a component has a 1.x or greater version, its behavior for specific signals might change in ways that break end users if the component is not stable for a particular signal.
+Go API stability guarantees apply to ALL signals, regardless of their stability level. 
+This means that signal-specific configuration options MUST NOT be removed or changed in a way that breaks our Go API compatibility promise, even if the signal is not stable.
