Version 2.2 ("Approaching perfection") - 2010/05/22:

  + New features
    - use 2 progress bars in copy/move/delete dialog, one for files count
      and other for files size
    - added recursive chmod chown chgrp
    - faster cursor movement
      . Ctrl-l: center cursor in panel, so now edit-link is in 'L'
      . Ctrl-cursor_up, Ctrl-P: move cursor 1/4th of page up
      . Ctrl-cursor_down, Ctrl-N: move cursor 1/4th of page down
      . P: move cursor 1/4th of page up in other panel
      . N: move cursor 1/4th of page down in other panel
    - file_menu new feature: a -> backup file. You can specify the extension
      to use in .lfmrc
    - added support for .xz compressed files
    - Unicode & Encodings
      . rewrite all internals to use unicode strings, but employ terminal
        encoding (f.e. utf-8) to interact with the user or to display contents
        in ncurses functions or to run commands in shell
      . when lfm detects a file with invalid encoding name it asks the user to
        convert it (can be automatic with the proper option in the
        configuration, automatic_file_encoding_conversion, default 0 (ask)).
        If not converted, lfm will display the file but won't operate on it.
      . try more encodings when we get a filename with strange characters
      . lfm will check and require a valid encoding before running
    - Pyview:
      . completely rewritten. Code is shorter and more beautiful now
        Uses a new FileCache class to accelerate the retrieving of file lines
      . displays contents between 2 and 4 times faster
      . new command line flag -s/--stdin to force reading from stdin.
        Now pyview doesn't wait for stdin input by default, so it starts much
        faster. eg. $ ps efax | pyview -s
  + Minor changes
    - add color entries for directories and exe_files
    - expand ~ to user home
    - make Tree follow .dotfiles behaviour, new keybinding Ctrl-H
    - dialogs are bigger now
    - show filesystem info rewritten
    - show file info rewritten, now it shows correctly information
      from fuse-mounted volumes
    - added new "ebook" category, filetypes and formats
  + About the code
    - since python v2.6+, popen* is deprecated, so make lfm check python
      version and use popen* or subprocess accordingly
    - correct some python idioms
    - clean code

  + Documentation
    - Added "Files Name Encoding" and "FAQ" sections
    - Added information about keybindings in permissions window
    - Updated some other minor changes: wide char support, vfs, thanks

  + lots of bugs fixed:
    - file system information was not showed correctly sometimes
    - devices major and minor numbers were not showed correctly
    - crash in goto_dir if there aren't any historic entries
    - crash in a void EntryLine after pressing BACKSPACE on some platforms
    - unzip => overwrite files without prompting ("unzip -o" option) to avoid
      ethernal waiting, as messages can not be seen by user
    - fix make_dir error message
    - recompressing a vfs compressed file leave some garbage on temporary dir
    - don't try to copy fifo/socket/block-dev/char-dev files
    - crash when we don't have enough permissions to write to dest
    - show_dirs_size: don't show in stderr if we don't have perms for a dir
    - can't browse /home/<user> as root if .gvfs is present
    - EntryLine: non-ascii chars are not showed correctly
    - lfm crashes with invalid encoding filenames
    - increment owner and group space to avoid ugly look in 1-pane view
    - when moving files, don't delete source if some error or if we don't
      overwrite destination

Version 2.1 ("What do you want for Christimas?") - 2008/12/21:

  + Ctrl-H now show/hide dot files
  + Ctrl-Y display directories history 
  + It's now posible to move the cursor in the non-active pane
    Consult the documentation for available keys and actions
    This behaviour is de/activated with Ctrl-W
  + added support for .7z compressed files
  + swapped F2 and F12 keys, now F2 rename files and F12 show file menu
  + new key shortcuts in dialogs. Read docs
  + speed up cursor movement
  + lots of code cleaning and refactoring
  + and fixed lot of bugs, some of them:
    - setup.py: change Iñigo for Inigo to avoid problems when installing
    - sorting by None doesn't crash anymore
	- MenuWin dialog crashed when title length was greater than length of
      entries to show

Version 2.0 ("Nine 1/2 weeks... ok, ok, and 3 years") - 2007/09/03:

  + tabs implemented
  + color files by extension [Andrey Skvortsov]
  + new IPC code and API; more flexible, powerful and stable
  + new un/compress vfs API, added support for .zip and .rar files
  + make sort mode per tab, not globally
  + support locale [Andrey Skvortsov]
  + speed up loading directory contents
  + speed cursor movement, don't waste much CPU
  + use logging module in lfm and pyview for debugging
  + overwrite_all_none: yes, all, no  => new options: "none", "skip all""
  + rewrite/refactor most of code to make lfm more robust and clean
  + preferences:
    - change file name preferences.py => config.py
    - use ConfigParser
  + use tempfile secure versions mkdtemp() and mkstemp()
  + added man pages [Sebastien Bacher]
  + use reST for documentation
  + check for python version 2.3 or higher in lfm and pyview
  + upgraded to GPL v3 license
  + and fixed lot of bugs, some of them:
    - general:
      . delete garbage if user stops action
      . run 'do_special_view_file' as dettached from lfm window
      . path expand in bookmarks ("~/") [Andrey Skvortsov]
      . an ugly traceback crash appears when user starts "lfm path" and has 
        no permissions to enter. Show error message and default to current 
      . lfm crashes when filename is not encoded with same codec than 
        g_encoding utils.{decode|encode}. Needs curses module linked against 
        ncursesw to work properly
      . sort_mix_cases = 1 performance degrades on larger dirs.
        Reported by Andrey Skvortsov
      . escape filenames with chars $ ". Reported by Andrey Skvortsov
    - user interface:
      . maximize/minimize window don't crash lfm anymore
      . dialogs appear at bad position after terminal is resized
      . handle window resize in Tree mode
      . refresh display after canceling completion dialog
      . "the size of the right pane does not fill the last column in 
        terminal if their number is odd" [Andrey Skvortsov]
      . fix crash when "df" shows entries in two different lines (device 
        name is too large, f.e. in linux lvm2 volumes)
      . if you try to enter a directory with insufficient permissions, after 
        the error message is closed the cursorline refreshes to the first line
    - compress:
      . added -i flag (--ignore-zeros) flag to tar [Andrey Skvortsov]
      . standard tar needs - for flags
    - vfs:
      . vfs.py: regenerate_file, if user stops process, tempfile can't be 
    - find/grep:
      . escape special chars (- \ ( ) [ ]) in patterns
      . don't crash when find/grep returns no results
      . bug when matches occur in binary files
    - pyview:
      . goto line 0 in pyview showed a blank screen
      . crash in file info if filename is too long

Version 1.0 was never publically released - 2006

Version 0.92 was never publically released - 2005

Version 0.91 ("It rocks... yeah!") - 2004/06/30:

  + quite stable and robust, doesn't crash
  + faster
  + new option: show_dotfiles flag
  + new option: detach_terminal_at_exec flag: useful f.e. if you 
    want to run elinks as web browser attached to lfm terminal
  + file associations and applications can be configured in preferences
  + now each application has only 1 associated program, *breaking old .lfmrc*
  + perms dialog: users & groups sorted alphabetically
  + uncompress in other panel
  + resizing terminal works in lfm, pyview. Be careful with dialogs
  + columns size eliminated from preferences
  + 1-panel view redesigned
  + ESC closes dialogs, not lfm or pyview
  + Ctrl-D: select bookmark dialog
  + code reorganized: actions.py, vfs.py
  + added classifiers to setup.py script

Version 0.90 was never publically released

Version 0.9 ("...and the day arrived") - 2002/09/05:

  + ZIP files can be un/compressed now. ZIP vfs works too
  + added 'rebuild vfs' and 'rebuild_vfs' question / option. Configurable.
    There is no need to wait until vfs file is rebuilt
  + Applied some good patches from Bartosz Oler (liar AT furrynet DOT org):
    1. colors customization: Now you can customize the colors lfm use in
       the configuration file, 'colors' section. Each color is defined by
       a string with its name. It looks like this:
	      element foreground_color background_color
    2. Allow preferences values to contain colons in the configuration file.
    3. Lack of a bookmark's definition shouldn't be an error.
  + pyview: new features:
      - read from stdin
      - go to / set bookmarks
      - open shell
  + pyview doesn't show blank screen a the end of the file, now it shows last
  + lfm works now with "from __future__ import division", prepared for Python 3.0
  + set python2 as default interpreter for setup.py, lfm, lfm.py, pyview and
  + my email address has changed <inigoserna AT telefonica DOT net>
  + Bugs fixes. See ChangeLog for complete list
      - lfm:
          * create temporary files with mask 0066 and directories with perms
            0700, so only owner can read/write them
          * avoid zombie processes when using 'fork' (now fork twice or threads)
          * show correct filename when an error occurs while uncompressing file
          * don't compress '..' directory
          * when lfm exits after checking command line options, make 'lfm' shell
            script don't show path error
          * when un/compressing files cursorbar must remain in the same file
          * when, at start, lfm can't enter into a dir due to directory permissions
          * crash if len(line) == width of cursorbar window
		  * don't append '*' to historic in entries
		  * fix cursor bar position after sorting
      - pyview:
          * when user hasn't permissions to read file, exit gracefully instead
            of crashing
          * last char in file is not showed

Version 0.8 ("Close to Paradise") - 2002/03/04:

  + Implemented VFS feature to enter into .tar.gz and .tar.bz2 files
  + Panelize vfs option in find/grep implemented
  + Tree panel implemented
  + 'lfm' and 'pyview' are simple scripts now, not just a copy of the .py files.
    __init__.py contains global variables now
  + A new message window is used to show  work in progress, in place of a
    message in status bar. 'run_thread' function has been cleaned too
  + Copy / move features now use my own function to walk trees, instead of
    'shutil.copytree' which originates some problems and bugs
  + In ChangePermissions window, the cursor movement is circular now
  + Change copyright date to years 2001-2
  + I don't need a crypt / uncrypt feature, so eliminated from TODO list
  + Many bugs fixes and functions rewrites. See ChangeLog for complete list
      - lfm:
          * if panel2 shows 'a' file in panel, and in panel1 'a' is moved or
            deleted, lfm crashes
          * after moving a file cursor goes to next directory as deletion does
          * catching an exception after not been able to copy => it crashed
            when trying to delete copied files
          * "messages.SelectItem, messages.FindfilesWin, messages.MenuWin,
            messages.ChangePerms: upperleft corner disappears"
          * findgrep: fix bug: if selected file has a ':' in name
      - pyview: 
          * changing 'addch' by 'addstr' shows individual chars >= 0xA0 (meta
            chars) correctly, neither in reversed video or as 2 chars
          * "if wrap mode => fix prev/next page & up/down cursor". Now 
            they move to screen lines, not to physical lines

Version 0.7 ("Hello Darling, I'm here") - 2001/11/30:
