Breaking changes ⚠

• env files loading is now more intuitive (#649)
  • Before the default .env file would only be loaded if no env files were explicitly passed through the -e flag, now it will always be loaded first if present
  • Before loading env files would not overwrite any env variable that had already been set before, now it does so when loading multiple files if a variable is set more than once the value from the last file to be loaded will take precedence.
  • Before the first file would take precedence, now, the last one will.
