On 15th March 2006 squashfs-tools 3.0 was released.

Changes in 3.0 version:

1. Filesystems are no longer limited to 4 GB. In theory 2^64 or 4 exabytes is
now supported.

2. Files are no longer limited to 4 GB. In theory the maximum file size is 4
exabytes.

3. Metadata (inode table and directory tables) are no longer restricted to 16
Mbytes.

4. Hardlinks are now suppported.

5. Nlink counts are now supported.

6. Readdir now returns '.' and '..' entries.

7. Special support for files larger than 256 MB has been added to the Squashfs
kernel code for faster read access.

8. Inode numbers are now stored within the inode rather than being computed from
inode location on disk (this is not so much an improvement, but a change forced
by the previously listed improvements).

There is a new Unsquashfs utility (in squashfs-tools) than can be used to
decompress a filesystem without mounting it.

Worth updating?
