v2.0.0

• Minor breaking change in the CLI: recur will process the options -h/--help and -V/--version like other options. This means they must be given before the first positional argument. In version 1.x, these options were special and processed in any position. It was supposed to make help easier to access, but in practice it caused problems more than helped. What this change means is that the option -h in the command recur ls -h used to make recur print help and exit; now -h is passed to ls.
• Replaced "flag" with "option" in the messages.
