[b0rne0]

What's main difference between MHDD 2.9 and 4.5 except for eng manual?
Why some feature in 2.9 have been removed?

Thank you.

Yes, I know the log changes. But why some command like ibme/fuj have been erased?
Thank you.

Because they are useless. And buggy. And as they are not needed, I decided to get rid of them
