Do I need to upgrade a BTRFS filesystem after upgrading Ubuntu, like I would with ZFS?
Why is BTRFS at 0.19 when the latest version according the the BTRFS wiki is 3.0?

(running Ubuntu 11.10)

Where do you see any reference to version 3.0? – psusi Jan 24 '12 at 1:49

He's probably referring to btrfs being included in Linux 3.0. – Jo-Erlend Schinstad Jan 24 '12 at 6:03
