 - Now time allows second precision (instead of daily precision) in storage on uint32 from 01/01/1950 to 01/01/2086
   New identifications are produced with this type, old files could still be loaded.
   If you use old identifications for tracking use the `--unraw` option to unpack old times and store data with the new format.
 - Now amplitude is stored with .1 mm of precision (instead of 1 mm), same advice as for time.
-- expose more parameters to users for bash tools build_network & divide_network
-- add warning when loading a file created from a previous version of py-eddy-tracker.
