2 v5_06  16/05/2005
 The following version numbers apply to this version of Mn_Fit:

 Mn_Fit      v5_06
 ZEUS_DSP    1.00/05

 This section lists the changes that have been made since
 Mn_Fit version 4.07/36. Check `HELP CHANGES V4_07' for a list of
 changes made in version 4.07, some of which you may have missed if you
 have been running a version earlier than 4.07/36.

 This release has been tested with the 2002, 2003 and 2004 releases of the
 CERN libraries. It has also been linked to the 98 version for
 CLEO. Depending on your version of gcc you may only be able to link with one
 of the versions. 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 cannot 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.

 COMIS has occasional problems on OSF1 machines (Cernlib 98).

 The ZEUS forward detector display has not yet been integrated into this
 version.


 +++ New Features:
 _________________


 Mn_Fit has moved to cpp and make. The VMS version is frozen.

 A first interface to ROOT histograms is available. This requires Mn_Fit to
 have been compiled with this option turned on and for you to have the root
 libraries available. At present you can only fetch 1-D and 2-D histograms -
 profile plots will be available soon. Variable bin-width histograms are also
 not recognised properly yet. You must give each histogram identifier (0 and a
 range of histograms do not yet work).

 Cernlib version 2002 is now the default, but another version may be used
 depending on the location.


 +++ New Commands:
 _________________


 ROOT_OPEN              Opens a ROOT file.
 ROOT_FETCH             Reads in ROOT histograms.
 FUNCTION ADD RCB       Adds a reversed CB lineshape function.


 +++ Modified Commands:
 ______________________


 NTUPLE MERGE           Internal changes to avoid segmentation violations.
 SET FIT AREA           Can also calculate area for ARGUS background function.


 +++ Improvements and Bug Fixes:
 _______________________________


 Cernlib version 2002 is now the default.

 First version of a ROOT interface is available.

 You can now use `SET FIT AREA ON' to also normalise the ARGUS background
 function.

 A new function `rCB' has a Crystal Ball lineshape, with an upper rather than a
 lower energy tail. Useful for beam-constrained D and B mass peak to include
 effect of initial state radiation, even though the parametrisation is Ad Hoc.

 Small bug in `SET FIT AREA' fixed. If you turned it off and then on again,
 and no parameters changed, e.g. in `FUNCTION PLOT' the integration was not
 redone. 

 `SHOW FILE' now shows names of current HBOOK and ROOT files.

 Can now fetch up to 1000 plots from an ASCII file without losing track of
 which were fetched.

 The Linux version has been made and tested most using make. Linux, OSF1 and
 SunOS versions have been compiled for CLEO using the 98 version of the CERN
 libraries and seem to work fine.

 Many improvements to Makefile.

 Add Makefile.user in order to make a user version of Mn_Fit.

 Some fixes to include files and a few source files to remove C type comments
 that came from conversion from CAR files to fpp files.

 The font was not set correctly for 2-D plots using the `COL/Z' option.

 `NTUPLE MERGE' uses separate HBOOK top-level directory names. This will
 hopefully avoid segmentation violations - does not seem to do the trick all
 the time.
