+   **Default Remote Update in Conan 2.9.2**
+
+   Starting from **Conan version 2.9.2**, the default remote has been changed to
+   `https://center2.conan.io`. The previous default remote `https://center.conan.io` is
+   now frozen and will no longer receive updates. It is recommended to update your remote
+   configuration to use the new default remote to ensure access to the latest recipes and
+   package updates (for more information, please read this `post
+   <https://blog.conan.io/2024/09/30/Conan-Center-will-stop-receiving-updates-for-Conan-1.html>`_).
+
+   If you still have the deprecated remote configured as the default, please update using
+   the following command:
+
+   .. code-block:: bash
+
+       conan remote update conancenter --url="https://center2.conan.io"
