What makes Rails 3 suave? Hear it from one of Exist's resident rockstars, Nuks.

1. Rails 3: A Cleaner, Faster and More Beautiful Rails -DHH 10/01/10 Wilfrido T. Nuqui Jr. (wnuqui@g2ix.com)

3. - more consistent and composable queries - complex queries are easy to build - on demand query execution New AR Query Engine

4. CODE

5. - complete syntax revamp - REST style with less noise and more flexibility New Router for AC

6. CODE

7. - now AM is all controller - now AC and AM share some code New AM

8. CODE

9. - before, all solutions are patchworks - config.gem, Capistrano externals, custom rake setup tasks etc - but now, all your application depends on are taken care of Bundler Dependency Management with Bundler

10. Ruby 1.9 tools + Rails 3 EQUALS ZERO "question mark inside a diamond" character Encoding Issues, Now a Thing in the Past

11. - a number of AR components now extracted for the GOOD of other Ruby Models: validations, callbacks, serialization and I18n support direct AC references of AR removed ORMs like DataMapper, Sequel or Mongoid can use AR's features: - form_for, link_to and redirect_to AR Components Used in NON-AR Models

12. - AP and Railties component both received surgery - rewrote made them now more flexible and easier to extend - from one monolithic AR::Base comes several modules that are: - with defined APIs - mixable to produce special-purpose controllers for a particular use - Django-style generic action can now be easily implemented in Rails - RG has got a revamp as well new RG can create generators for other frameworks like rSpec, DataMapper and Haml Rewritten Internals

13. - now, Rails is JS framework, Test framework and ORM agnostic - "Web Development That Doesn't Hurt" -> "Have It Your Way" Not Just DB Agnostic

14. - wealth of Guides, tutorials, screencasts, official videos - and there are still more coming in terms of these wealth Documentation
