Yep, version 1.2.0 is already available.

What's new over version 1.1.4?

For the invisible part, code has been re-factored in some ways.
For what you will notice:

• Filesystem name is now less truncated (ie: something like /dev/mapper/home/foo was previously truncated to /dev/mapper causing the loss of useful information and is now truncated to /dev/mapper/home)
• Default behavior is now to print size in human-readable format (other options still available)
• -b option to display size in Bytes (which was the default previously)
• -i option prints information about the number of inodes and the available ones

Well, I think dfc is getting more mature. Hope you enjoy and do not hesitate to contact me if there is a feature that you would like to see implemented or if you encounter some bugs!
