Unicorn is an HTTP server for Rack applications designed to only serve  
fast clients on low-latency, high-bandwidth connections and take  
advantage of features in Unix/Unix-like kernels. Slow clients should  
only be served by placing a reverse proxy capable of fully buffering  
both the the request and response in between Unicorn and slow clients.

Changes:

This release includes small changes for things allowed by Rack  
1.1. It is also now easier to detect if daemonized process  
fails to start. Manpages received some minor updates as well.

Rack 1.1 allowed us to make the following environment changes:

- “rack.logger” is now set to the “logger” specified in  
the Unicorn config file. This defaults to a Logger  
instance pointing to $stderr.

- “rack.version” is now at [1,1]. Unicorn remains  
compatible with previous Rack versions if your app  
depends on it.

While only specified since Rack 1.1, Unicorn has always exposed  
“rack.input” in binary mode (and has ridiculous integration  
tests that go outside of Ruby to prove it!).
