* Releases
  --------
    - 21.0.18 available since yesterday, express stream and DRAW production running now,
       should be done by tomorrow 

    - 21.0.19 coming tomorrow, hopefully (several infrastructure issues recently, RTTs, ..)
      - Contains tags to fix tracking/egamma electron efficiency loss, ATLASRECTS-3949,
          huge amount of work done over the weekend
      - Will also contain last minute fix of jet moments bug, JetMomentTools-00-03-61

* Likely configuration for reprocessing
  -------------------------------------
    - Release: 21.0.19-gcc62
    - Geometry tag: ATLAS-R2-2016-01-00-01
    - Conditions tag: CONDBR2-BLKPA-2017-03 (perhaps -04, tbd)
    - AOD reduction: enabled

* Inputs
  ------
    - 2016 runs: 182 physics_Main
    - 2015 runs: 112; 106 physics_Main and finally 6 physics_MinBias (period B)
    - Further streams to come too

* Schedule
  --------

   0) 21.0.19 build tomorrow, distribution by the evening

   1) Depending on speed of the distribution, late Weds night / early Thurs morning:
      -> launch 17 2016 express runs + usual DRAW samples
   
   2) Potentially send those same 17 runs of physics_Main on Fri, maybe some delayed until Mond
      -> Here is where we will need the minimum 80k slots, more would be better

   3) End of next week: first large submission of runs, around 80 from 2016,
        list to be added to the Winter2017Run2Reprocessing twiki

   4) Add in further 2016 runs, then 2015

   5) Additional, smaller streams
