The documentation on the site contains a section on “Upgrading to Middleman 4”. It also refers to “v4 betas”.
However, in my exploration of the site, I haven’t seen anything that says whether we’re encouraged to start using v4 (“Go ahead, give it a whirl”) or to wait until it’s more stable (“Stand back! It’s gonna blow!”).
If it is possible to start using v4, what’s the procedure? I presume that ‘gem install’ will still get the current v3 version. Is there a simple guide to getting started with v4?
