-         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.
