           PIPE-8030: Reflex: Handling of interactive widnows for science recipes
           PIPE-6745: Execution of stare and sky-mehod=BSPLINE using poly mode fails
           PIPE-8173: Reflex fails on demo data

v 3.2.0 (2018-04-01):
  -3.1.9b1  02/07/2018 Update user manual and reflex tutorial with comments from Sabine
  -3.1.8    01/07/2018 Update doc for release
  -3.1.7    31/07/2018 Fix residual actions for pub release update (PIPE-7826,PIPE-7894,PIPE-7793,PIPE-6985)
                       PIPE-7826: answered questions about sky subtraction (MEDIAN) in xsh_scired_slit_stare
                       PIPE-7894: Update the SCRIPTS_DIR path in the Gasgano preferences for Paranal
                       PIPE-7793: xsh_mflat: clarified differences in bad pixels flagged in slit master flat fields between 2.5.4. and 3.0.6
                       PIPE-6985: xsh_scired_slit_stare: PRO.CATG of products created with do-optextract=true not documented, and clarified 
                                  optimal extraction documentation.
  -3.1.6    17/07/2018 Fix PIPE-7935: NIR flux STD fails more and more
  -3.1.6    27/06/2018 Fix PIPE-7075 (extrapolated flux in flat fields should not cause "calibration file defect" in later processing steps)
  -3.1.5    19/06/2018 rolled back (removed) pixel quality ingestion during resampling to improve results of resampled 2D. 
                       The residual quality problems in the NIR and good seeing VIS are due to improper flagging of sky lines 
                       (or even order edges as CRH). In those cases one should rather disactivate CRH rejection (removecrhsingle-niter=0)
 
  -3.1.4    14/06/2018 Injestion bad pixels during resampling
  -3.1.3    13/06/2018 Merged branch release_320 to head
  -3.1.2    05/06/2018 fixed PIPE-7833,7182: clarifying sky extraction ranges and restoring old simmetric limits to model the sky during stare data reduction 
  -3.1.1    08/05/2018 Fixed computation efficiency (wrong sign atm exctinction) to address PIPE-7836
  -3.1.1    30/04/2018 Changed extraction slits as indicated by Sabine to fix PIPE-6779

v 3.1.0 (2018-04-24):
  -3.1.0    12/04/2018 Public release
  -3.0.8    10/04/2018 Merged BP scaling project changes
  -3.0.7    05/04/2018 Removed flagging as QFLAG_INCOMPLETE_DATA of bad pixels during simple pixel stacking (crh_multi), as asked by Sabine.
  -3.0.6    27/03/2018 Do not ingest bad pixels during frame resampling as it creates hairy effects on strong NIR tellurics
  -3.0.1    28/03/2018 Fix a bug found from Mubashir testing. 

v 3.0.0 (2018-04-01):
 _-2.9.5    21/12/2017 changed xsh_wavecal followarclines-search-window-half-size parameter to 13 to have correct spectral resolution values

  -2.9.4    13/11/2017 Version to test new esoreflex-2.9.0
  -2.9.3    27/06/2017 Fixed PIPE-7257 fixed UMR that was creating seg fault on Mac
