 All changes to the Metis L1 pipeline are documented in this file.
 
 ## 3.0 - 2021-07-19
+- Modify the pipeline to manage the new input I/F which includes the full set of Solar Orbiter SPICE kernels and the Metis Calibration Package. In the input file contents.json, the two fields TLS_FILE_NAME and TSC_FILE_NAME are now replaced by the field SPICE_KERNELS providing the path of the Solar Orbiter SPICE kernels folder. The field CAL_PACK_PATH is added to provide the path of the Metis Calibration Package folder.
 - Add the WCS (World Coordinate System) keywords to the FITS header and a set of routines to perform calculation of the instrument boresight parameters and S/C coordinates.
-- Modify the pipeline to handle the new input I/F which includes the full set of Solar Orbiter SPICE kernels and the Metis Calibration Package.
-- Add the derivation of the quality matrix which is now added in an extension to the L1 FITS file.
-- Add several code optimisations.

 	- the fact that the GEN_TIME keyword is provided in UTC rather than OBT.
 - Fix a bug that prevented the correct update of some keywords of the FITS header, in particular those related to sensor temperatures, whose values are interpolated using the input house-keeping parameter table.
 - Add correct computation of the TELAPSE and XPOSURE keywords.
-- Include the EMPTY_PARAMS keyword in the output auxiliary JSON file, containing the list of house-keeping parameters in the input table that are not calibrated but which have been interpolated to correct the value of some of the FITS header keywords.
+- Include the EMPTY_PARAMS field in the output auxiliary JSON file, containing the list of house-keeping parameters in the input table that are not calibrated but which have been interpolated to correct the value of some of the FITS header keywords.
 - Revise the structure of the binary table containing the house-keeping parameters to make it more user-friendly.
