A new version of the Btrfs file system has been released - 0.17 .
Six months after the last release, a new version of the Btrfs file system was released - 0.17, on which the code included in the future Linux kernel 2.6.29 will be based . The importance of version 0.17 is to fix the disk format, which will no longer change, except in cases involving the finding of critical errors. The final stable release of Btrfs 1.0 will be released during 2009, although initially it was expected at the end of 2008.
Among the innovations of Btrfs 0.17 we can note:
1. Support for transparent data compression (mount -o compress);
2. Improving the mechanisms for distributing data blocks;
3. The ability to associate created Btrfs partitions with previously existing ones (device seed), while the previously existing partition is used as a frame operating in read-only mode, and changes within the directory tree are saved in a new section;
4. Improving the sharing of blocks during the transfer of extents. For example, in the new version, the situation of simultaneous use of blocks in different snapshots is handled much better, while writing to the COW (Copy On Write) log;
5. Bug fixes and performance optimization.
