   3 News:
   4  upcoming relevant meetings:    
   5     → SM@LHC, 9-12 Apr, Freiburg (HERA, LHC talks)
   6     → PDF4LHC, 17th April, CERN,: dedicated talk (VR)
   7     → DIS13, April, Marseille: dedicated talk (RP)
   8     → 5th Workshop of the APS Topical Group on Hadron Physics, 10-12 Apr, Denver, Coloraro (LHC talk)
   9     → Abstract submitted to LHCP 2013 May, Barselona

  11  - the HERAFitter-0.3.0 version is released and is publicly available, details:
  12    - theory files have been separated from tar file, can be downloaded from the web page
  13    - registration will no longer be required
  14    - significant efforts on documentation: writeup, doxygen, release notes
  15    - new download page which includes manual, release notes, links to external packages and HERAverager
  16 
  17 Revised HERAverager release candidate is in preparation, more stable version available but 
  18 requires more improvements (plotting tools), plan to release: end April
  19    
  20 Post beta-3 developments stays same, progress on Offset method in new chi2 scheme and code restructuring,
  21 OpenMP code parallelisation (work in progress), improved plotting tools.     
  22     
  23 ===> presentation on QCDNUM CQD-QED evolution status, M. Botje:
  24  - work ongoing, progress from last time in memory management, evolution tool. User's interface
  25    and backward evolution is still to do, first beta release is expected next week for tests. 
  26 
  27 
  28 ===> presentation on ACOT update, F. Olness:
  29   - updated status on k-factor issues, general suggestion to use 3 iterations to get stable 
  30     result vs true chi2 value (comment received: in HERAFitter currently several iterations are not 
  31     available, requires implementation), using full NLO results avoids K-factor problems but one has
  32     to deal with numerical inaccuracies (possible to tune, would be useful to document), idea
  33     to use HQSTF package from QCDNUM (Fixed Flavour) for k-factor technique. Aim for future - use 
  34     ACOT QCDNUM package.
