Hi Pete, I just noticed this the other day..
The documentation states that the 'formatter' option only applies when minify is set to false.
However in 2.0, I compiled using 'minify=>true' and 'formatter=>block', and the CSS file that was output was not minified but was block formatted. I had to unset the 'formatter' option to get minification.
Just wanted to give you a heads up. Thanks.
Yes, this was updated recently so if a formatter is set it will override the minify option.
It's in the changelog but the online docs have not been updated. I'll do that when I get a second.
