Documentation request - v2.0 and v2.1

[hyperman2]

I notice there is not yet a 2.1 tag, and maybe you also want to add upgrade instructions for v2.0 and v2.1, documenting which settings have been added and removed..

I don't see the -d flag mentioned in the docs.

In general, I'd suggest you document settings in table form, with 4 columns: Name, default, available version range, description.

Anyway, thanks very much for all your hard work. It's very rare to see such a huge laundry list of issues fixed in such a short amount of time.
