Btrfs has received much of the limelight on Linux when talking about file-systems since it promises to compete with Sun's ZFS file-system and introduce several features not found in the commonly-used EXT3 and EXT4 file-systems. However, work on other Linux file-systems hasn't halted. EXT4 should be stable with the Linux 2.6.28 kernel and work on the Tux3 file-system continues.

We last talked about Tux3 file-system in September and just this past week the project's Daniel Phillips has shared a progress report. Up until recently, work on the Tux3 file-system was done as a Linux FUSE module, but work is well underway in a kernel port for Tux3.
