Classic Ladder history
----------------------

v0.1 (February 2001 - Not released)
    - The first lines of codes for calculating one rung and displaying it...
    - Basic elements and timers

v0.2 (30 April 2001 - First public release)

v0.2.8 (3 August 2001 - Featuring the Editor, but not totally completed)
    - Basic Editor (allow to modify only the current rung, properties uncompleted)
    - Makefile and modifications to allow independent object compilation.
    - Fixed bug for drawing in calc.c

v0.3 (18 August 2001 - Editor completed)
    - Variables Parser completed for Mxx,R and Txx,D and Txx,R
    - When clicking on "unusable" blocks (part of big element), it is as
      if you've clicked on the "alive" block itself.
    - For timers and monostables , parameters Base and Preset.
    - Can modify label of the rung to jump to for -(J) coil.
    - Label / comment of rung saved when edited.
    - We must not allow to change of current rung when editing one.
    - Add/Insert/Delete a rung, buttons usuable.
    - Load/Save/SaveAs/Run-Stop/About buttons added in main window
    - Load/SaveAs using path selection requester (datas should be in a directory).
    - Save rungs,timers,monostables parameters.

v0.4 (20 October 2001 - Arithmetic expressions evaluator)
    - New variables memory type : Words (integers)
    - 2 new elements using arithmetic expressions :
      COMPARE and OPERATE
    - Load/Save the file of arithmetic expressions
    - Possibility to spy the values of any variables by typing its name
      (added in the bottom of the vars window)
    - Added new types of variables : physical inputs (I) / outputs (Q)
      (not linked to anything in this version)
    - Resizing of rung take into account and thick lines for active wires
      (modifs initially done by Jiri Baum when integrating classicladder
      into the MAT project)

v0.5 (30 December 2001 - Real time support)
    - ClassicLadder_gtk.c created from file classic_ladder.c which keep only the
      global variables + 2 fonctions for loading/saving directory datas.
    - Global variables are now allocated and freed.
    - RTLinux support added.
      The refresh of the rungs are done in a RTLinux module in real-time.
      The Gtk application compiled for this version do not refreh the rungs.
      The Gtk application and RTLinux module share the same global variables
      allocated with mbuff.
    - Physical inputs and outputs have the same memory as the bits (VarBits + offsets).
      (if we make polling on them in RTLinux module with inb() and outb(),
      we could drive real hardware directly !?)

v0.5.1 (4 January 2002 - Parallels ports interface)
    - Direct hardware support of the parallels ports (in real-time version).
      Comment the line define HARDWARE_SUPPORT in classicladder.h if you do not want it !
    - Bug if there was no element in the first column, fixed (in function StateOnLeft())
    - Overflow possible (1 char) for label and comment strings in the rung, fixed.

v0.5.2 (26 January 2002)
    - Added in the editor the nice long connection (-->) to create rungs faster.
    - In Operate elements, you should now write the formulas like the following:
      A:=B instead of A=B
    - Draw a grid in edit mode.
    - #include <rtl.h> removed in hardware.h as it seems not to work with kernel 2.2
      causing an error when compiling : duplicate module kernel version...
    - Removed the warnings when compiling for RTLinux.
    - For big element, at the point you click, it is the left-top corner of the element
      which is inserted instead of right-top (the "alive" one).
    - Confirmation box before deleting the current rung (indispensable!)
    - 'New' button with a confirmation box also ;-)
    - Bug (exception) possible, if replacing for example a contact with a timer, where
      the number of the bit in the contact was greater than the timer number allowed.
      Now the number is erased if a simple element is not replaced by a simple
      element, to avoid that.
    - When deleting the current rung, the arithmetic expressions used on that rung were
      not deleted. Fixed.

v0.5.3 (11 May 2002)
    - Taken the current sources of classicladder from the MAT tree.
      So that we will have the same sources on the two sides...
      There is a define in the Makefile MAT_CONNECTION to be able to
      create the mat connected version for the MAT project.
    - The real-time support was broken in the MAT version.
      Modified the way to alloc/free booleans variables so that it works back.
      Now it should works for the 3 possibles versions : normal, real-time and mat.
      Note: it is not possible to include "mbuff.h" in many sources files : otherwise
      we have multiple definition when linking of some functions...
    - Modified Makefile for easier real-time generation.
      make rtl_support ; make test is enough for the rtlinux version
    - The feature that everybody was waiting for : added a vertical scrollbar to
      show many rungs at the same time...
      The current rung is the one with the blue bars.
      The current rung is set automatically for the moment : it is the rung which is at
      the top and that is fully visible...
      There are still some visual troubles when adding/inserting a rung, but not really
      serious... to be modified in a future version.

v0.5.4 (22 May 2002)
    - Sometimes, at the end, the last rung was displayed 2 times : for example if
      there was only one rung existing and you increase the vertical display...
    - During edit mode, if you clicked outside of the current rung (top or bottom),
      it was accepted and making strange things.
    - Now when you insert or add a rung, you have a correct display of the rung before
      or after the new rung you are adding.
    - Problem when adding or inserting if the current rung is the first one. Fixed.
    - If the vertical size was less than enough to see a complete rung, there was no
      more current rung. Fixed.
    - Do not allow to set 'connection with top' if on the first line of the rung.
      As we have now many rungs, it was as if 2 rungs could be linked ! ;-)

v0.5.5 (18 August 2002)
    - Added And, Or and Xor operators in the evaluator : & , |, ^
    - Added hexadecimal constants support in the evaluator with the first carac : $
    - Display formats : Dec/Hex/Bin for vars spy.
    - Bug-fixed if compiled for Windows : '\' used instead of '/' for directories.
    - Show the duration of the last scan of the rungs in micro-seconds if calc of the
      rungs is done under RTLinux.
    - Program can be split in many sections : new window 'Sections manager' added.
    - New format of the rungs files including Prev & Next rung informations. When saved,
      the rung number do no more change.
      Warning, old classicladder versions will not be able to read these new files !
    - New (C)all coil for sub-routines.
    - Modified RefreshAllRungs( ) for taking into account the main sections and the
      calls to sub-routines.

v0.6.0 (2 November 2002 - Birth of a new language)
    - Added a new language : "Sequential" (sometimes also called Grafcet).
    - New variables supported : Xxx and Xxx,V for the steps of the sequential.
      Xxx is activity of step xx.
      Xxx,V is activity time of step xx.

v0.6.1 (23 November 2002)
    - The RTLinux version support was completely broken (perhaps since v0.5.5).
      Now it works correctly as before.
      Tested here with a fresh installed RTLinux3.2pre1 with kernel 2.4.18.

v0.6.2 (23 March 2003)
    - When launching classicladder, you can give now an argument with the path
      of the files to load.
    - Horizontal & vertical scrollbars when displaying sequential added.
    - Xxxx and Xxxx,V variables now use the step number defined for each step
      instead of the number in the array.

v0.6.3 (15 April 2003)
    - Embedded version possible without the Gtk interface
      (comment GTK_INTERFACE in the Makefile).

v0.6.4 (19 July 2003)
    - Possibility to load a config file at startup with the sizes of differents
      arrays to alloc. Interesting for really embedded system where there isn't a
      lot of memory. Patch send by Thomas Gleixner.
    - Some big variables only usefull for editor no more allocated if compiled for an
      embedded target without GTK. Patch send by Thomas Gleixner.
    - Possibility to build a library with ClassicLadder. Patch send by Thomas Gleixner.
    - Parameters added to the RTLinux module to be able as in the normal version
      to use the sizes choosen.
    - Made a script (run_rt) to be able to launch the real-time version without having
      to use the Makefile for that, and made the necessary to pass the sizes parameters
      to the RT module.
    - Add a config window with the sizes actually allocated and the percent of use for
      some of them.
    - When a ladder section was deleted, the rungs associed to it were not freed.
    - In FindFreeRung( ) start to search from rung 0 instead of the FirstRung value !?

v0.6.5 (17 August 2003)
    - Physical inputs/outputs interface completly rewritten :
      Removed the parallel ports access code.
      Added possibility to map the logicals I/O of classicladder with any addresses ports
      or a Comedi device (www.comedi.org). Thanks to Edouard Tisserand for that nice
      idea and for the 'LinuxInControl' workshop at Leuven to let me discover
      that project.
      Parameters can be easily edited in the new tabs "Inputs" and "Outputs" in
      the configuration window.
      New file : ioconf.csv in the projects directories.
    - Calling ioperm( ) to allow to read/write adresses ports directly
      even if not under RTLinux ! (but you must be root, so that it works...)
      A lot of people wanted it : no real-time, but hardware access under Linux, which
      is enough and easier in schools to learn ladder programming!
    - In the RTLinux module, added binary parameter "COMEDI_TO_OPEN_MASK" which
