   5 1) in the status presentation:
   6 
   7 - functionalities of the new upcoming release were presented
   8 - the upcoming new release will be a beta and made publicly availabe 
   9   for the next HERAFitter User's meeting to be fixed via doodle
  10 - almost 90 downloads till today, 31 developers
  11 
  12 
  13 2) Update from Fred Olness group: ACOT status and issues
  14 
  15 - implemented and will be available in the next release 
  16   the NLO based kfacctors (from QCDNUM) for F2 and FL (and F3)
  17   for Fc, Fb will still be based on LO (massive)/NLO (massive).
  18   This is currently working only for NC, plans to extend for CC too.
  19 
  20 - variations of the scales muf and mur (muf used to regulate the IR 
  21   collinear singularities, mur to regulate UV divergences).
  22   For ACOT Full mur=muf=mu, however it can be generalzed later (this convention
  23   avoids extra log terms).
  24   For ACOT ZM: Based on Furmanski & Petronzio; can be generalized.
  25   For ACOT chi : Complete up to NLO-Quark term; can be generalized.
  26 
  27 
  28 3) Michiel Botje: QCDNUM QCD+QED evolu/on status update
  29 
  30 - large efforts to write an evolution toolbox where the	
  31 user can feed-in the splittin functions, perturbative expansion
  32 coefficients ents and do n-fold	coupled	evolutions.
  33 
  34 A list of steps should be performed to complete the task.
  35 The ready steps are:
  36 
  37 o Basic nxn evolution routine	
  38 o Loop over subgrids
  39 o New address mechanism for PDFs
  40 
  41 Time scale is of order of a month to complete the 
  42 next steps which includes also user interface and writeup.
  43 
  44 
  45 4) Andrii Gizhko presented the scale variation for DIS in the HERAFitter
  46 and a proposal how to unify these treatments for user steering options.
  47 
  48 - presented an overview of current possible options for mur and muf scale variations
  49 - a simple relation to treat the scle variations is proposed. Scale setup for FF, FF ABM, 
  50   ACOT Full, ACOT Chi and ZMVFNS was implemeted and tested.
  51 
  52 5) status update on HERAverager from Pavel Belov
  53 
  54 - The compatibility with the HERAFitter has been improved:
  55 o usage of the environment variables for calling of the
  56   HERAFitter, longer file names in the HERFitter itself.
  57 o The dimensions of the internal arrays has been ajusted to
  58   work on different computer systems and it seems that it
  59   works well, but probably takes more memory than needed.
  60 o The averaging of the multiple processes has been tested.
  61   The results are good, but it revealed the necessity to
  62   improve the output format and to make more flexible
  63   plotting tools
  64 
  65 - ongoing cleaning of the package before releasing it.
