A bold step towards maturity. Great care was taken to
fix reported bugs and fine tune many aspects of Nitro and Og.
As always some great new features where added. Special thanks fly
to Jonas Pfenniger, Bryan Sotto, Rob Pitt and Guillaume
Pierronnet for making this release possible.

Most notable changes:

* Greatly improved error detection and report. Nitro now provides
  line exact error reports at compile or run time, in actions
  or templates. Stay tuned for more improvements in error
  handling.

* Nitro now supports a very useful url endoding/decoding system
  along with a Camping inspired R operator. This new system allows
  you to refer to controllers and actions in your code, without
  bothering about the enforced nice urls and rewrite/routing
  rules. This allows you to write more robust code.

  Here are some examples:

  redirect R(UsersController, :login, :name, 'gmosx')
  delete

  some more helpers and better integration of this feature
  will be available soon.

* To better support the URL codec, a new router was implemented.
  The new version is both more powerfull and faster. Here are
  some examples:

  r.add_route(%r{rewritten/url/(.*)}, :controller => IdController,
:action => :register, :param => :name)
  r.add_route(%r{another/zelo/(.*)/(.*)}, :controller =>
AdminController, :action => :kick, :params => [:name, :age])
  r.add_route(%r{cool/(.*)_(.*).html}, :controller => AdminController,
:action => :long, :params => [:name, :age])

* Og now supports calculations and aggregations. Here are some
  examples:

  User.min(:age)
  User.average(:age)
  User.maximum(:age)
  User.min(:age, :group => :profession) # => [..] (aggregation)
  User.sum(:age, :group => :role) # => [..]

  and more!

* Improved template_root handling. Now Nitro automatically generates
  a template_root stack for each controller / publishable object.
  Of course the developer can fully customize this stack.
  This is great for reusable modules of functionality (parts). Lets
  say you have implemented a forum part. When you 'mount' the
  forum controller a path relative to the mount point is pushed
  in the template_root stack. When the dispatcher searches for
  a template, it traverses the stack. In the described scenario
  it first looks in the application template root, next in a template
  root the points inside the part template root and then in the
  proto dir template root. The proto dir template root is automatically
  pushed as the last root in the stack. This system facilitates
  'object oriented sites'.

  Use the following method to customize the template_root.

  def self.setup_template_root(path)
    ...
  end

* Added support for JSP like application scoped (global)
  variables.

  def login
    ...
    global[:users] << current_user
    application[:users] << current_user
    ...
  end

  The global/application hash is backed by any of the available
  cache stores.

* Improved Taggable mixin, now provides more helpers and supports
  tag garbage collection through reference counting.

* Added a new store for the generalized caching system that is
  backed by a MemCache server. Useful to extract the last ounch
  of performance in a production environment.

* Fixes in the SCGI adapter.

* Many Og bug fixes and optimizations.

* More flexible static include compiler.

* Improved testing support.

* Integrated latest versions of Scriptaculous and Facets.

* Many, many bug fixes and small improvements throughout the
  code.


Nitro provides everything you need to develop professional Web
applications using Ruby and Javascript. Nitro redefines Rapid
Application Development by providing a clean, yet efficient API,
a layer of domain specific languages implemented on top of
Ruby and the most powerful and elegant object relational
mapping solution available everywhere.


have fun,
George Moschovitis
