Version 1.2.1

Major changes

• New safelist class for lists of SAFE Sentinel-2 archives (see safelist-class);
• sen2r() execution now causes saving the used parameters in a json file located in ~/.sen2r/proc_par (this can be used to take trace of the executed processing chains);
• safe_getMetadata() function was rewritten: now files are scanned only if the user requires metadata which must be retrieved from file content, otherwise only file names are analysed.
  Inputs can be also safelist objects.
  The support for oldname SAFE products is deprecated.

New functions / methods

• link_sen2cor() can be used to link an existing Sen2Cor installation to sen2r;
• as() methods can be used to convert safelist from/to character, data.frame and data.table (as well as as.character()', as.data.frame()andas.data.table()` functions).

Changes in default values

• safe_getMetadata(): new arguments format, simplify and allow_oldnames (see the function reference for details);
• s2_list(): argument output_type was deprecated (use as.data.table to obtain a data.table instead than the new default safelist object);
• safe_shortname(): arguments tiles, force_tiles, set.seed and multiple_names were deprecated, since they are not used with SAFE compact names (old names are no more supported);

Minor changes

• Sys.setenv() effects now do not affect the R environment after exiting from sen2r() execution;
• safe_shortname() does no more support oldname SAFE products;
• the Docker version of the package was modified to support last package changes;
• the delay between SciHub registration of new credentials and the possibility to use them on API hub is now documented in the GUI;
• return a warning in case some LTA orders cannot be processed because user quota exceeded.
