v2.1.0

Added

• New --app-data option for overriding the location of the application data directory.
• New migrate subcommand which may be used to perform migration steps manually.

Changed

• The default location for the default YAML file (recyclarr.yml) has been changed to the
  application data directory. This is the same location of the settings.yml file.
• Automatic migration has been removed. Instead, the migrate subcommand should be used.

Deprecated

• The recyclarr.yml file should no longer be located adjacent to the recyclarr executable.

Fixed

• Version information in help output has been fixed.
• If a HOME directory is not available, throw an error to the user (use --app-data instead).
• Create $HOME/.config (on Linux) if it does not exist.
• Smarter migration logic in the trash-updater migration step that does a directory merge instead
  of a straight move. This is designed to fail less in cases such as recyclarr directory already
  existing.
