ReactOS是一些高手根据Windows XP的内核编写出的类XP。内核实现机理和API函数调用几乎相同。甚至可以兼容XP的程序。喜欢研究系统内核的人可以看一看。

Version 3.5

- New hotlist code.

	  The features it presently supports are: Block copy, move,
	  delete, cut, paste; key for key undo; file insertion; macro
	  definition; regular expression search and replace (and our
	  own scanf-printf search and replace); shift-arrow MSW-MAC
	  text highlighting (for the linux console only);
	  insert-overwrite toggle; and an option to pipe text blocks

	  interesting to search inside virtual file system: tar files,

Version 3.0

This has been finished:

- Virtual File System: You now can browse tar, compressed tar and 
  file systems over the network as if they were local subdirectories;
- Slang support, you don't need ncurses anymore (but you can still compile
  with ncurses, if you want).
- New mc.ext format, for details see the sample mc.ext file provided.
- Append option if you try to copy/move a file onto already existing one.
- Internal cd command uses CDPATH variable if set (like in BASH).
- Find file command is much faster.
- External panelize command - finding files using unlimited number of
  criteria - actually spawns an external command and it can be find, awk,
  grep -l or anything else.
- Learn keys makes setting up of mc on terminals with broken
  terminfo/termcap databases easier. It just asks you to press keys which
  are not working.
- Advanced chown command.
- C-PgUp and C-PgDn takes you to the previous and currently selected
  directory respectively on the Linux console.
- You can choose between 7 data bits, iso-latin-1 (0-127+160-255) or
  other (0-255).
- Confirmation for overwriting, deleting and exiting added.
- Viewer has growing buffers.
- Filename, username, hostname and variable completion (M-Tab) on all
  input lines plus command completion on appropriate places of command
  line.
- Following of symlinks at changing directory.
- Viewer now supports bold faces and underlines, and it fits the 
  information on the screen better.  Now you can also specify the starting
  mode for the viewer depending on the contents of the viewed file.
- Mask rename and copy.
- Colors now let you specify the intensity of the colors you want.

This is being worked on:
- Virtual File System: FTP file system.
- Tcl/Tk and XView versions of the program (preliminary versions are
  up and running).


Version 2.0

Now users are able to define their own display 

- User defined display formats.

  Now you can configure the file display to suit your needs.
  For example, you can say which information you want to see displayed
  instead of our defaults.

- User definable program layout.

  Panels could be shown vertically or horizontally;
  panels could be different sizes, you can hide or show most
  program windows (command line, keybar or menubar).

- Output window.

  Now, it's possible to see part of the last program output on the Linux
  console without having to switch screens via an option in the layout
  menu.

- New View modes:

     Quick view: as you browse your files, each one is displayed on
                 the other panel on the idle time.

     Tree view:  let's you browse your directories by traveling a tree.  
		 We have two traveling modes available.  And the tree does
  		 not take your precious time: it's build on the fly, as you
                 browse your disk (you can always loose your time if you
		 want to :-).

     Info view:  Gives you information on the currently select file and
                 the current file system as you move.

     User view:  Let's you define a directory listing and the format you
                 want to use.

- New subshell support (concurrent shell execution)

  The Midnight Commander will now spawn one copy of the shell, so you
  get better performance and you can use shell functions, define variables
  and execute complete shell commands.  Supported shells: bash, zsh and
  tcsh.  If your shell is not supported, then the old mode is still
  available.

- Dialog box manager
