Version 406 was released on 19 Jun 2007.

These are the differences between version 394 and version 406:

• Allow decimal point in number for % (percent) command.

• Make n command fetch previous pattern from history file on first search.
• Don't rewrite history file if it has not changed.

• Make -f work for directories.
