 This section lists the changes that have been made since
 Mn_Fit version 3.02/16.

 +++ Known Bugs or Problems:
 ___________________________

 `NTUPLE MERGE' only allows you to put 1 Ntuple in the merged file.

 Storing of plots in anything other than the top HBOOK directory does not
 work properly.

 `SQUEEZE' sometimes gives errors.

 This release does not work with CERNLIB release v92b on Unix machines.
 It has been fully tested with CERNLIB release v92a.

 If you use the mouse with the DECGKS version you get error message 51
 from GINLC. This is not a problem, so you can ignore it.

 The Falco interface to DECGKS does not work perfectly. Pictures get drawn
 twice sometimes, and the alphanumeric screen is cleared after each picture.

 The `SHOW' command calls the corresponding `SET' command if the `SHOW'
 does not exist. If you are asked to set a value you wanted to show, just
 hit `<CR>'.

 +++ New Features:
 _________________

 Startup in X Windows much improved. If you have the DISPLAY variable
 defined, then you can just hit <CR> when asked for the screen device.
 X Windows version on the Vax works properly. You can give the display
 name and transport mechanism in the command to run Mn_Fit.

 New options in `PLOT/OVERLAY', `PLOT/NEXT' to draw the next plot in
 memory. You can include the symbol number with the `PLOT' command.

 You can now convolute a fitting function with a Gaussian resolution.
 See HELP SET FIT CONVOLUTE for more details.

 The proper area of fragmentation and dipion invariant mass functions can
 be calculated. You can specify whether a dipion function is for a charged
 or a neutral pion.

 It is possible to produce profile plots from Ntuples.
 See HELP NTUPLE EPROFILE and NTUPLE SPROFILE for more details.

 Once you have fetched an Ntuple that is stored with the disk option,
 it is no longer necessary to fetch it again before you can project it
 etc., even if you have fetched histograms or Ntuples from another
 file. This is because the HBOOK directory name is remembered by Mn_Fit.

 Ntuples can be stored in HBOOK files.

 You can use `IF' statements inside macros.

 You can reduce the size of an Ntuple, using the `PROJECT' command.

 Mn_Fit works fully on SGI, Decstations, SUN  and IBM RISC machines.
 Implementation of other Unix machines should be very simple.
 An environment variable (MN_FIT) rather than links is now used and
 you can also use environment variables in filenames.

 On Decstations and SGI machines VMS like command line editing and recall
 works, e.g. up arrow to get back last command.

 Editing and shelling out of Mn_Fit should work properly on all
 machines. On the Apollo you can also use editors other than dm.

 New commands for shifting and scaling axes (`XSHIFT', `XSCALE', `YSHIFT',
 `YSCALE', `ZSHIFT', `ZSCALE').

 Superscripts, subscripts and Greek letters are available with
 Postscript fonts, e.g. font -2013 with X-windows.
 See HELP Text for more details.

 The simulated VMS Help (used on Unix machines) has been improved and
 can now show lists of commands (`?'), ambiguous commands, and all
 subcommands (`*').

 Motif added as a screen device for DECGKS and DEC GKS3D.

 You can get nice Postscript circles (also filled) as symbols by using
 symbol 10 (or 20, 30, 40) and the `SET DSIZE' command.
 See HELP SYMBOLS for more details.

 +++ Modified Commands:
 ______________________

 STORE           Can now store Ntuples.
 HELP            Has extra options on non-VMS machines.


 +++ Improvements and Bug Fixes:
 _______________________________

 Mouse handling of comments and keys much improved. The comment or key
 is shown immediately after you click on the mouse and the mouse gives
 the centre of the comment position.

 Ntuples can now be stored in HBOOK files. However this is currently
 restricted to Ntuples that are stored in memory.

 The number of words for HBOOK has been increased to 800 000 and for
 Mn_Fit is now set to 750 000 on Vax and 1 000 000 for both on Unix
 machines.

 In Unix, Mn_Fit looks for `mn_logon.mnf' in the current directory.
 If it cannot find this file it now looks for `$HOME/.mn_fitrc' instead
 of `$HOME/user_data/mn_logon.mnf'.

 Asymmetric errors were used upside down when fitting a plot with them.

 Vax editors are always spawned, because of a problem with v92b of the
 CERN libraries. This will be fixed.

 `IF' did not always work properly. The buffer was not being cleared out
 correctly. A CDE was missing when parsing `IF' also.

 Histograms of functions did not have the axis labels or contents assigned
 correctly.

 CERN routines are used for getting the time, so Mn_Fit times should be
 correct and available on all machines.

 User variables were not always parsed correctly, particularly when inside
 parentheses.

 If you try to add a COMIS function that has an error when compiling,
 it will not be added.

 The first underflow bin was being projected into the first bin of an
 Ntuple projection.

 `CENTRE' and `CENTER' are both valid for comment postioning, although
 `C' is adequate.

 `DRAW LIST' now shows the correct item name.
 `DRAW CHANGE' allows to you change items other than the last one.

 The Unix version now uses a single environment variable (MN_FIT) rather
 than symbolic links. This means that you can delete any links that you
 have in your home directory (e.g. ~/mn_fit_dir, ~/mn_fit_exe, ...).

 Bugs were fixed in the `INCLUDE' command.

 Output conversion errors in MN_DMP fixed. If they happen they should no
 longer kill Mn_Fit.

 Plot positioning in windows should be correct for all X-window shapes.

 `HARDCOPY -111' etc. should work fine with GKSGRAL, DECGKS etc.

 Bug fixes when projecting a table of numbers stored in an Ntuple. The
 error was not done correctly or could have been the square root of the
 correct value.

 `INTEGRATE' has been improved to use Simpson integration.
 It should also give the correct answer, even when integrating a
 mixture of functions such as Gaussians and Chebyshevs.

 The symbol number is passed correctly, even when plotting a range or
 histograms or when you are asked if you want to keep comments and/or keys.

 All versions of Mn_Fit now get the date and time correctly.

 Changing the title position when windowing with 0 separation between
 the plots affected the number of header lines. The number of header
 lines was not always calculated correctly.

 Improved calculation of the minimum number of ticks, also when windowing.

 The default shell is set to `$SHELL' and also works for 8 letter shells
 such as `/bin/tcsh'.

 `FUN FETCH' should work properly even when fetching plots stored with a
 different function number with `FUN STORE' in an older version of Mn_Fit.

 Error bars should no longer be drawn outside the plot.

 User variables were sometimes not recognized properly, for example
 when used as histogram identifiers.

 Multiple //PAWC/TMP directories should no longer be created when
 merging Ntuples.

 Minor fixes to C. Rippich version of MINUIT for Decstations.
