Versin 0.17 of the Linux filesystem btrfs has been released. The main news on this release is that it has been included in the Linus' tree. The changes include support of transparent compression, seed devices, improved block sharing while moving extents, improved block allocation and many bug fixes and performance improvements. Also, the disk format is not expected to change unless a critical bug is found.
