Dear devs, I am pleased to announce new versions of Nitro and Og homepage: [http://www.nitrohq.com](http://www.nitrohq.com) download: [http://rubyforge.org/projects/nitro/](http://rubyforge.org/projects/nitro/) mailing list: [http://rubyforge.org/mailman/listinfo/nitro-general](http://rubyforge.org/mailman/listinfo/nitro-general) irc: [irc.freenode.net](http://irc.freenode.net) #nitro # What new This is the first in a series of releases focused on stability and refinement. Many bugs where fixed, the high level api was improved where needed, and we still got some small but incredibly useful new features. Enjoy! Most notable changes: - Support for constrained / scoped queries in Og, here are some examples: - Dynamic auto generators, you can now query the database in English: - Added experimental version of a new schema evolution system. Assuming evolve\_schema = true and evolve\_schema\_cautious = false - Template morphing now handles nested elements, an example: - Added some useful helpers to make the code you write cleaner, here are some examples: - New, improved, clean taggable implementation. This new implementation supports polymorphism. - Added useful StaticInclude as a separate compiler module to act as the first stage in the compilation pipeline. - Integrated latest versions of Prototype, Scriptaculous, KirbyBase and facets. - General code cleanup and refactoring. - Many, many bug fixes, including security fixes. # What is Nitro? 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. Nitro is Web 2.0 ready, featuring excellent support for AJAX, XML, Syndication while staying standards compliant. Enjoy, George M. ---
