There is some rack 1.0 legacy code that could be removed. Rails switched with 2.3.6 – it's at 2.3.9/3.0.0 now ;) – from 1.0 to 1.1, so I don't see a reason Sinatra shouldn't.
If I remember right, rack 1.1+ doesn't work with ruby 1.8.6. I'd have verify that though.
No, that's 1.2+, 1.1.0 works perfectly fine on 1.8.6.
Require at least Rack 1.1.0. Closed by 89af8c1.
