On 25 June 2013, the directorate of Deutsches Elektronensynchrotron DESY, a research centre of the German Helmholtz-Gemeinschaft, announced the long-awaited primary version of GFITTER.  
See:

http://fh.desy.de/projekte/gfitter01/Gfitter01.htm

This version of Gfitter is labeled version 01.
It was packed on 21 June 2013.

The only interesting part of the package, for friends of ZFITTER, is the package

Gfitter/gsm.

The files in Gfitter/gsm originated between 25 September 2012 and 12 March 2013.
Comparing the package Gfitter01 with the Gfitter version which was used e.g. by Gfitter in March 2011, it becomes evident at first glance that the two programs differ.
The reader may prove this by visiting http://zfitter.com where the original Gfitter/gsm is made publicly available, respecting the corresponding licence conditions.

One comment is at place:

At about 98 occasions, in the Gfitter/gsm files it is indicated that code has been created with active use of ZFITTER Software version 6.42.
- added on 11 Aug 2013 -
Additionally, the Gfitter01/gsm classes BosonPart.cxx, EW2Loop.cxx, FermionPart.cxx, QCDCorrections.cxx, RadiatorFunctions.cxx, Vertex.cxx, WZFitter.cxx contain global introductory statements like "... This class also contains code lines ported to C++ from the Fortran package ZFITTER".
It will be interesting to see the overlap with the findings of the ZFITTER authors of about 175 cases.

DESY says:

"Publications making use of this code are listed here.
From the talks and proceedings listed here the ones up to July 2011 are based on this version."

Although the reference to "this version" is not correct, let us follow DESY insofar as the reader may assume [and interested people know] that the truly used Gfitter/gsm code also relies in about 98+ cases, or so, on ZFITTER.

But this use of ZFITTER for creating of Gfitter/gsm was never announced in the article linked and in the corresponding 14 talks and proceedings linked.

The stringent conclusion is that the scientific representative of DESY Professor Helmut Dosch provides herewith, with full authority and responsibility, the official proof that the Gfitter authors have used ZFITTER, but did never attribute this properly.
Over years, from 2007 (first public representation of the project) to 2011.

Further comments will follow soon.
