The following enhancements were made:

• Quiet mode (--quiet) no longer suppresses errors.
• Help output has been improved and made more succinct.
• Running F2 without arguments now shows a short help message.

1.7.0 (2021-08-04)

This release brings the following improvements:

• CSV support (See renaming from a CSV file).
• Improved no color options. You can now set the F2_NO_COLOR environmental variable or use the brand new --no-color flag to disable coloured output.

The previous backup directory (~/.f2/backups) is still supported (in case you have existing backups there), but new backup files will not be created there anymore. This change was made to conform to the XDG specification and conventions for storing application files on each operating system, and to avoid cluttering up the home directory.
