What's new in Sinatra 1.4?

came from python (and tornado) to ruby, if it wasnt for sinatra, i'd have stayed with python and tornado. great work, keep up the clean syntax and lightweightness.

I'm glad there is Sinatra because it inspired Scalatra, which seems way more lightweight than Play :-). Keep up being lightweight!<p>I don't blame the authors for discontinuing old branches (1.2.x), but it makes me hesitant using Sinatra for a production website that's meant to be there for &#62;= 2 years (though is an eon in IT).

&#62; By default, Sinatra will now only serve localhost in development mode. You should not be running your production system in development mode.<p>This "opinionated default" makes it very hard to test when you're running your development environment from a virtual machine, like Vagrant.<p>More and more people are doing this (gotta use those extra cores + memory for something, right?), so please consider us before adding a "listen 127.0.0.1". :)

For static sites I use rack, for dynamic sites I use rails.<p>When do I use Sinatra?
