Dear devs, The Nitro Development Team is proud to announce new versions of Nitro and Og homepage: [http://www.nitroproject.org](http://www.nitroproject.org) install: gem install nitro download: [http://rubyforge.org/projects/nitro/](http://rubyforge.org/projects/nitro/) trac: [oree.ch](http://devlab.oree.ch/trac/nitrohq) irc: [irc.freenode.net](http://irc.freenode.net) #nitro faq: [http://oxyliquit.manveru.net](http://oxyliquit.manveru.net) mailing list: [http://rubyforge.org/pipermail/nitro-general/](http://rubyforge.org/pipermail/nitro-general/) Another pragmatic release. The Nitro development team worked over the submitted tickets and provided many bug fixes. More over, there are many small improvements along the codebase and as always we could not resist adding some cool new features. Special thanks fly to Bryan Sotto for making this release possible! Most notable chages: - Nitro allows fine grained customization of the compiler tranformation pipeline per controller or even per action. Here come some examples: - Nitro automates integration testing by means of the new session VCR feature that allows for easy proxy based functional testing. A typicall session goes like this: - Better Global variable implementation works better with distributed stores (Drb, Memcached). Notice the new Global.init and Global[:key].update { |v| } methods. - Improved the Router implementation. One notable addition is support for global router initialization: - Cleaned up glue by removing files duplicating functionality allready available in Facets. Moreover, we moved several generally useful files and methods from Glue to Facets. - Replaced the old RSSHelper with the new FeedHelper. The new implementation provides support for RSS, Atom, OPML. The FeedHelper is backwards compatible with the old helper but provides even more features. - Added Og query by example support. Query the database for an entity that matches the example. The example is a hash populated with the property values to search for. - Added type casting support for Og aggregations and calculations. - Greatly improved the configuration system. One noteable (and extremely useful) new feature is that you can now customize classes before they are even defined: - Calculate rendering level in actions to allow for conditional rendering in top level actions or sub-actions. Some helpers are also provided: - Introduced an alternative more sophisticated (yet intuitive) form builder. While this new helper is still under construction, it is already very useful. Here come some examples: - More flexible Script generator, the developer can use most of its features without a Client subclass. - Reimplemented session garbage collection. - Added many more RDoc comments to the source code. - Many, many bug fixes. - Updated to latest Facets, Scriptaculous, Prototype. 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.

Wow… sounds like a ton of excellent features. I’ve done a Google search to find a comparison of Nitro and Rails, but didn’t see much other than a couple of blog posts. Do you guys have a comparision or any other sugggestions about how to understand the approaches and benefits to different development communities of Rails and Nitro?
