Improved stability and test suite .
The beta period took a while because we wanted to ensure that the first stable release is indeed rock solid. People tend to say that one should skip "x.0.0″ releases and wait until "x.0.1″ for the first bug fixes. But we're confident enough about the stability of the 4.x series that we gave this first release the version number 4.0.1 .
Changes in 4.0.1
Compared to 4.0.0 …

…take multiple requests at a time, but it is by no means the only option when it comes to concurrent Rack servers. Another popular alternative is Puma which uses threads instead of forking processes. Puma does however require that your code is threadsafe .
If you've never run a concurrent server in production, we encourage you to spend some time exploring the ecosystem. After all no one knows your app's requirements better than you.
