Forum: Ruby [ANN] Rack 1.5.0, a modular Ruby webserver interface

Hello,

Today we are proud to announce the release of Rack 1.5.0.

= 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

Please note that this release includes a few potentially breaking 
changes.
Of particular note are:

 * SessionHash is no longer a Hash sublcass
 * Rack::File cache_control parameter is removed in place of headers 
options

Additonally, SPEC has been updated in several areas and is now at 1,2.

A new SPEC section was introduced that provides two server-optional IO 
hijacking
APIs. Further information on these APIs will be made available by the 
community
in good time. In the mean time, some information can be found in the 
original
pull request: https://github.com/rack/rack/pull/481

* January 21st, 2013: Thirty third public release 1.5.0
  * Introduced hijack SPEC, for before-response and after-response 
hijacking
  * SessionHash is no longer a Hash subclass
  * Rack::File cache_control parameter is removed, in place of headers 
options
  * Rack::Auth::AbstractRequest#scheme now yields strings, not symbols
  * Rack::Utils cookie functions now format expires in RFC 2822 format
  * Rack::File now has a default mime type
  * rackup -b 'run Rack::File.new(".")', option provides command line 
configs
  * Rack::Deflater will no longer double encode bodies
  * Rack::Mime#match? provides convenience for Accept header matching
  * Rack::Utils#q_values provides splitting for Accept headers
  * Rack::Utils#best_q_match provides a helper for Accept headers
  * Rack::Handler.pick provides convenience for finding available

  * Various middleware now correctly close body when replacing it
  * Rack::Request#params is no longer persistent with only GET params
  * Rack::Request#update_param and #delete_param provide persistent 
operations
  * Rack::Request#trusted_proxy? now returns true for local unix sockets

  * Rack::Sendfile provides local mapping configuration options
  * Rack::Utils#rfc2109 provides old netscape style time output

SPEC still says this:

  <tt>rack.version</tt>:: The Array [1,1], representing this version of 
Rack.

I take it 1,2-compliant servers should set [1,2] there instead?

Cool.  Should be easy for unicorn, and some configurations of 
Rainbows!/zbatery.
