-   `@BetaApi` features are also marked with `@BetaApi`. Features marked as
-   `@BetaApi` are on a path to eventually become "1.x" features with the marker
-   removed.
+1. Components marked with `@ObsoleteApi` are stable for usage in the current major version,

+   **NOTE**: We reserve the right to mark anything as `@Deprecated` and introduce breaking
+   changes in a minor version to fix any ***critical bugs and
+   vulnerabilities***.
