4.6.4 released on 21-MAY-2011

  Problems fixed:

     * Name completion did not expand a single tilde as a home
       directory.
     * A mouseclick on a certain screen area of the help panel
       could lead to a crash.

  New or improved functionality:

     * The English documentation was proofread and corrected,
       the service was kindly contributed by Richard Harris.
     * Text file preview function was added.
     * The initial working directory for the secondary file
       panel is now set by a bookmark named DIR2. This
       replaces the configuration parameter DIR2.
     * The initial working directory for the primary file
       panel can be now set by a bookmark named DIR1.
     * New configuration parameter TIME_DATE controls the
       display of date and time.
     * Changes to the mouse control were made.
     * The recommendation against using alt-R for normal file
       renaming was dropped.

4.5 released on 24-SEP-2009

  Problems fixed:
     * Name completion could not complete user and group names
       containing a dot, comma or a dash character.

  New or improved functionality:
     * A mouse is supported on xterm-compatible terminals.
     * The location of configuration files has been moved
       again in order to comply with the XDG Specification.
       The standard place for these files is from now on the
       ~/.config/clex directory. Use the 'cfg-clex' utility to
       move the files to the new location.
     * There is a new option in the completion panel which
       allows completion of a name which is a part of a longer
       word. The option has a self-explaining description:
       'name to be completed starts at the cursor position'.
     * Configuration parameter C_PANEL_SIZE (completion panel
       size) cannot be set to AUTO (screen size) because this
       size is often uncomfortably small.
     * The Unicode soft hyphen character is displayed as a
       control character.
     * In the history panel a command separator is
       automatically inserted into the input line when a
       command is appended to the end of another command.
     * Configuration parameters CMD_Fn accept a new control
       sequence $~ which disables the 'Press enter to
       continue' prompt. The control is returned to CLEX
       immediately after the command execution terminates
       provided that:

          * the command has not been modified; and
          * the command terminates successfully (exit code
            zero).

     * The $! control sequence can appear anywhere in a
       configuration parameter CMD_Fn, not only at the end.
     * New function: alt-Z places the current line to the
       center of the panel. People using cluster-ssh might
       find it useful.

4.4 released on 07-APR-2009

  Problems fixed:
     * In the help text there were few UTF-8 characters which
       are now eliminated because they could not be displayed
       properly in non-UTF-8 encodings.

  New or improved functionality:
     * New function was added: change into a subdirectory
       showing the contents in the other file panel (alt-X).
       This function allows a return into the original
       directory simply by switching panels (ctrl-X).

4.3 released on 29-MAR-2009

  Problems fixed:
     * A newly added bookmark did not appear on the screen
       immediately.
     * A misleading message 'Ignoring the DIR2 configuration
       parameter' was logged when the 'DIR2' was set to
       'HOME'.

  New or improved functionality:
     * The bookmark organizer has been merged with the regular
       bookmark panel.
     * Bookmarks can have descriptive names.
     * The current working directory can be bookmarked from
       the file panel (ctrl-D).
     * The 'B_PANEL_SIZE' config parameter was removed.

4.2 released on 15-MAR-2009

  Problems fixed:
     * In some cases the 'cfg-clex' utility was generating an
       unusable template for the copy command (F5).
     * Under certain circumstances a crash was occurring on
       exit when CLEX was used over a ssh connection.

  New or improved functionality:
     * All configuration files now reside in the .clex
       subdirectory. Use the 'cfg-clex' utility to move the
       files to new location.

4.1 released on 09-FEB-2009

  Problems fixed:
     * Usage of uninitialized memory during the start-up has
       been corrected. It caused a crash on the Apple Mac OS X
       platform. Systems where CLEX starts normally are not
       affected by this bug.
     * A compilation problem on Apple Mac OS X was fixed.
     * The xterm title change feature did not work on remote
       telnet or ssh connections.

  New or improved functionality:
     * If a directory comparison is restricted to regular
       files, then only information about this type of file is
       displayed in the summary.
     * A small program named 'kbd-test' was added. It is a
       utility for

CLEX 4.0 released on 22-DEC-2008

   This is the initial release of the CLEX 4 branch. Main new
   features are:
     * Unicode support was implemented.
     * Several configuration parameters have been converted to options
       which are saved automatically.
     * The log panel and optional logging to a file for auditing and
       troubleshooting were added.
     * There is now 'cfg-clex' utility.
     * A built-in function for renaming files with invalid or
       unprintable characters was added.
   Enhancements (compared to previous releases) include:
     * Configuring prompt, time format and date format is more flexible.
     * The help is not limited to one link per line.
     * The user interface of the directory compare function was redesigned.
     * Changes in the pattern matching routine were made
     * Panel filtering is now available in two more panels.
     * A new tool for inserting control characters into the input line
       was added.
