 # Changelog
 
+## openfeature/v0.2.0
+
+- Dispatch on `SelectedVariant#fallback_reason` so `MISSING_CONTEXT_KEY`,
+  `NO_ROLLOUT_MATCH`, and `BACKEND_ERROR` map to distinct OpenFeature
+  responses instead of every fallback collapsing to `FLAG_NOT_FOUND`.
+  Requires `mixpanel-ruby >= 3.3.0`.
+
 ## [openfeature/v0.1.0](https://github.com/mixpanel/mixpanel-ruby/tree/openfeature/v0.1.0) (2026-05-13)
 
 Initial release of the Mixpanel OpenFeature provider for Ruby.
