New in Btrfs-progs 0.18 (Feb 9, 2009)
- v0.18 has the same disk format as 0.17, but a bug was found in the ioctl interface shared between 32 bit and 64 bit programs. This was fixed by changing the ioctl interface. Anyone using 2.6.29-rc2 will need to update to v0.18 of the btrfs progs.
- There is no need to reformat though, the disk format is still compatible.
