-          Btrfs is a new filesystem with extents, writable snapshotting,
-          support for multiple devices and many more features.
+          Btrfs is a general purpose copy-on-write filesystem with extents,
+          writable snapshotting, support for multiple devices and many more
+          features focused on fault tolerance, repair and easy administration.
 
-          Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
-          FINALIZED.  You should say N here unless you are interested in
-          testing Btrfs with non-critical data.
+          The filesystem disk format is no longer unstable, and it's not
+          expected to change unless there are strong reasons to do so. If there
+          is a format change, file systems with a unchanged format will
+          continue to be mountable and usable by newer kernels.
+
+          For more information, please see the web pages at
+          http://btrfs.wiki.kernel.org.
 
           To compile this file system support as a module, choose M here. The
           module will be called btrfs.
