 The following version numbers apply to this version of Mn_Fit:

 Mn_Fit      4.07/33
 Mn_Util     1.12/33
 TYPSCN      1.02/18
 CGR_MINUIT  1.00/15

 This section lists the changes that have been made since
 Mn_Fit version 4.06/14. Check `HELP CHANGES V4_06' for a list of
 changes made in version 4.06, some of which you may have missed if you
 have been running a version earlier than 4.06/14.

 This release has been tested with the 99 and 2000 releases of the
 CERN libraries. Versions earlier than 98 are known to have date/time
 problems.

 +++ Known Bugs or Problems:
 ___________________________


 `DRAW' commands with the mouse on only work in CM.

 You cannnot give a range of array elements to use in a `CUT'
 command. This only works in the variables to be projected. If you
 need to do something fancy like this you have to use a COMIS function
 for the cut.

 You can only access a variable in a CWN using the `DEPOSIT/EXAMINE'
 commands. It is not possible to access array elements this way.


 +++ New Features:
 _________________


 Cernlib version 2000 is now the default.

 This version of Mn_Fit is Y2K compatible.

 CWN variable names of up to 32 characters are now supported.

 `CUT' expressions can now be up to 255 characters long.

 The colour of symbols, hatchs and patterns can be given with the
 `PLOT' command and for the `FUNCTION PLOT' and `OVERLAY' commands.
 You can also define your own colour names for up to 20 different
 colours.

 `DRAW SEGMENT' draws the segment of a circle using the endpoints and
 sagitta (useful in Feynman graphs etc.). `SET IGARC' turns on/off
 using HIGZ IGARC routine for circles, as it appears to have a bug
 that cause it to ignore what you set for colour and thickness.

 Font -1004 is default for all sites and platforms. This means that
 the text stays as it was on the screen, but uses Helvetica Poscript
 fonts when you print the pictures - see HELP Text for more
 information.

 The underflows and overflows for the default plot are now also stored
 in registers >230. 200 user variable names are now available.

 You can use `..' instead of backslash to go up 1 HBOOK directory
 level. Multiple `..' will not work. HBOOK directory names can contain
 spaces. Enclose the name in quotes.

 You can use the syntax `SET DUMP SCREEN' to direct dump output to the
 screen and `SET DUMP > [filename]' to direct dump output to a file
 (alternatives to `TTY' and `LPT', as these terms are no longer in
 common use).

 The command `HMERGE' has been introduced to allow the merging of
 CWN's and complete RZ files.

 You can set the paper size using the `SET PAPER' command.

 The `HELP' text (and therefore also the manual) has been proofread
 and many corrections and improvements have been included.


 +++ New Commands:
 _________________


 DRAW SEGMENT           Draws a circle segment using endpoints and sagitta.
 HMERGE                 Merge one or more HBOOK RZ files into a single file.
 HPRINT                 Calls HPRINT for an HBOOK histogram.
 TEXT                   Same as `COMMENT' command without specifying the plot
                        identifier (planned, but not yet implemented).
 SET COLOUR DEFAULT     Set the colours to the default HIGZ colour scheme.
 SET COLOUR BACKGROUND  Give a background colour for plots.

 SET DUMP >             Alias for `SET DUMP LPT' with optional filename.
 SET IGARC              Uses HIGZ IGARC routine for circles or Mn_Fit code.
 SET PAPER              Set the paper size.


 +++ Modified Commands:
 ______________________


 CUT                    Expressions can now be up to 255 characters long.
 PLOT                   Allow colour to be given with the symbol,
                        hatch and pattern.
 OVERLAY                Allow colour to be given with the symbol,
                        hatch and pattern.
 FUNCTION PLOT          Allow colour to be given with the symbol.
 FUNCTION OVERLAY       Allow colour to be given with the symbol.
 SET COLOUR ON          Turns back on colour, but does not change
                        the colour map.
 SET PLOT id DEFAULT    Also fills registers with underflows and
                        overflows.


 +++ Improvements and Bug Fixes:
 _______________________________


 Cernlib version 2000 is now the default.

 A serious bug was found when combining simple cuts (numbers or
 registers used for cut values) with more complicated expressions. The
 cut values could be overwritten - see HELP CUT for more details. This
 has been fixed in version 4.07/30. Thanks to Ahren Sadoff for
 spotting this and providing an example.

 You can given the symbol, hatch and pattern colours with the `PLOT'
 and `OVERLAY' commands. You can give the symbol colour with the
 `FUNCTION PLOT' and `FUNCTION OVERLAY' commands.

 Colour handling has been improved. You can name your additional
 colours and up to a total of 20 colours are allowed. From version
 4.07/29 onwards 50 colours are allowed.

 Polygons can have up to 200 points (used to be 50). You can draw up
 to 2000 items now. Gluon drawing in plot coordinates should now be
 correct (the endpoint was drawn in slightly the wrong place.

 Drawing of first/last items should now be much improved. There were
 bugs in the old handling of items that should be drawn first in
 `PLOT' coordinates.

 User variable lengths of 8 characters are properly enforced and a
 warning is given if you try to make one that is longer.

 As a result of the above, the function `DATE_TIME' has been renamed
 to be `DATE_TIM'.

 Added MNSTAT to the list of known routines, so that one can find out
 how many parameters are being fit etc in COMIS routines.

 Along with the support for variable names of up to 32 characters in
 CWNs, the checking of the variable name has been improved, so that
 abbreviations do not work anymore.

 Length of many character variables increased to cope with long
 filenames etc. HBOOK subdirectories can be up to 16 characters. This
 is an RZ restriction.

 The `SET PLOT id DEFAULT' commands now also fills registers with
 underflows and overflows. Before version 4.07/20 it also overwrote
 registers 1 to 27. `SET HIST' did not recognise correclty that a
 command line was finished.

 The number of user variables names has been increased to 200.

 HBOOK and Mn_Fit commons increased in size for CLEO.

 Opening of an RZ filename with uppercase letters and the wrong record
 length should now work.

 It should now be possible to open and close many HBOOK RZ files. The
 command `HCLOSE' should close all files properly. It was not clear if
 it was really doing its job before.

 You can use variable numbers instead of the name for CWNs in the
 `NTUPLE PROJECT' command. However, this only works for single
 variables and not arrays, so is not recommended.

 Dumping of row-wise Ntuples gave screwed up numbers.

 Up to 100 subdirectories are shown with the `LDIR' command. Previous
 limit was 20.

 Help for polynomial function corrected. Help for ARGUS background
 function also corrected.

 Spurious lines drawn in overlays should no longer happen.

 Internal names of GETLUN routines have CLEO_ added as a prefix to
 avoid conflicts with ADAMO.
