Is there update required (new oxide version or we can use old form 6th dec) cuz now server update live and want to add oxide before client update or have to start without it for now.

oxide already updated 

Merged post

Usually oxide updates every month after the rust update hits

Oxide shows last update was 3 days ago, so it's not up to date with the update that was released 6 minutes ago.

Soon daniel son soon. They usually release updated umod version pretty quick.
