From: Christian Neukirchen on

Today we are proud to announce the release of Rack 1.2.

= Rack, a modular Ruby webserver interface

Rack provides a minimal, modular and adaptable interface for developing
web applications in Ruby. By wrapping HTTP requests and responses in
the simplest way possible, it unifies and distills the API for web
servers, web frameworks, and software in between (the so-called
middleware) into a single method call.

The exact details of this are described in the Rack specification,
which all Rack applications should conform to.

== Changes

* June 13th, 2010: Tenth public release 1.2.0.
* Removed Camping adapter: Camping 2.0 supports Rack as-is
* Removed parsing of quoted values
* Add Request.trace? and Request.options?
* Add mime-type for .webm and .htc
* Various multipart fixes
* Switch test suite to bacon

== Where can I get it?

You can download Rack 1.2 at

Alternatively, you can checkout from the development repository with:

git clone git://
cd rack && git checkout rack-1.2 # for this release

== Supported web servers

The included *handlers* connect all kinds of web servers to Rack:
* Mongrel
* EventedMongrel
* SwiftipliedMongrel
* WEBrick
* LiteSpeed
* Thin

These web servers include Rack handlers in their distributions:
* Ebb
* Fuzed
* Glassfish v3
* Phusion Passenger (which is mod_rack for Apache and for nginx)
* Rainbows!
* Unicorn
* Zbatery

Any valid Rack app will run the same on all these handlers, without
changing anything.

== Supported web frameworks

These frameworks include Rack adapters in their distributions:
* Camping
* Coset
* Halcyon
* Mack
* Maveric
* Merb
* Racktools::SimpleApplication
* Ramaze
* Ruby on Rails
* Rum
* Sinatra
* Sin
* Vintage
* Waves
* Wee
* ... and many others.

Current links to these projects can be found at

== rack-contrib

The plethora of useful middleware created the need for a project that
collects fresh Rack middleware. rack-contrib includes a variety of
add-on components for Rack and it is easy to contribute new modules.


== Installing with RubyGems

A Gem of Rack is available at You can install it with:

gem install rack

I also provide a local mirror of the gems (and development snapshots)
at my site:

gem install rack --source
