v1.0.0:

- For IDP generation: If present, the header keywords "ESO PRO TECH"
  and "ESO PRO SCIENCE" are inherited from the first raw file and
  propagated to the idp product.

v0.9.9:

- For IDP generation: When computing SNR related header keywords from
  the SNR vector the cleanup "do not use values with SNR <= 0" has
  been removed as it introduces a bias.
  
- For IDP generation: Averaging of the following keywords added: "ESO
  QC AIRM" and "ESO QC FWHM"

v0.9.8:

- Changing the content of the IDP keyword TITLE from "DUMMY" to TITLE
  = <OBJECT>_<DATE-OBS>_STACK for the file with PRO.CATG =
  ESOTK_SPECTRUM_IDP_FORMAT
  
v0.9.7:
- The output product header of the recipe esotk_eop has been changed
  to be ESO conform, i.e. ESO.PRO.TYPE header keyword has been changed
  to the value "STATIC"
- A bug in the recipe esotk_spectrum1d_combine has been fixed for the
  use-case that the destination wavelength is provided by the user and
  not taken from the first input spectra. The ESO.PRO.CATG was not
  properly recognized by the recipe.
- Update of the build system and compiler flags

v0.9.6:
- The pipeline has been updated to the latest hdrl (1.5.0) and cpl
  (7.3) release.
- Update of the build system and compiler flags

v0.9.5:
- The computation of the IDP keywords WAVELMIN and WAVELMAX has been
  changed for the esotk_spectrum1d_combine recipe. The calculation now
  considers only valid flux values, i.e. if a flux value of a given
  lambda is marked as bad, this wavelength it is not considered when
  deriving the minimum and maximum. Please note, that changing
  WAVELMIN and WAVELMAX also alters the IDP keywords SPEC_BW and
  SPEC_VAL.
- A new recipe to download the latest version of the Earth Orientation
  Parameter from IERS (esotk_eop) has been added to the pipeline and
  the manual. The downloaded file can replace the older static
  calibration frame provided by the pipeline when computing the
  barycentric correction with the esotk_barycorr recipe.

v0.9.4:
- The esotk_spectrum1d_combine recipe has been updated to work also
  with non IDP data and new QC parameter were added to the product.
- A new recipe to derive and on request apply the barycentric
  correction (esotk_barycorr) has been added to the pipeline and the
  manual.

v0.9.3 (2021-05-20):
- Esoreflex plotting routines updated to work with recent wxPython
  versions.

v0.9.2 (2021-04-01):
- IDP keyword of the esotk_spectrum1d_combine recipe updated. The TUCD
  keyword for the CONTRIB column has been changed to contain
  'meta.number'.
- The internal hdrl software has been updated to version 1.3.0
- The m4 macros has been updated to facilitate installation of the
  pipeline.

v0.9.1 (2020-05-25):
- Rewritten reflex tutorial and updated demo data.
v0.9.0 (2020-05-19):
- Preparing public release
v0.8.5 (2020-04-08):
- Preparing public release, initial verifications
v0.8.4 (2020-04-01):

- Following table 16 of the latest ESO DICD document the
  esotk_spectrum1d_combine recipe was changed to only allow "angstrom"
  as input and not anymore "Angstrom".

- Reflex python scripts have been ported to python 3 keeping the
  backward compatibility with python 2 and tested with esoreflex
  2.10.0

v0.8.3 (2019-09-19):

- Following the Phase3 convention: keyword SPEC_BIN is now always
  given in nm.
