 .. note::
 
-   Trame v2 is under active development.
+   Trame v2 is replacing trame v1 by providing even more flexibility and deployment capabilities.
+   Now trame officially support desktop, client/server, cloud and Jupyter as execution environment.
+   But we also refined trame API to make it more robust and future proof.
+   Some deep redesign will also allow integration of trame components into existing Web applications
+   while also streamlining community contribution for new widgets.
