Ruby on Rails 3.0 Release Notes

Rails 3.0 is a landmark release as it delivers on the Merb/Rails merge promise made in December 2008. Rails 3.0 provides many major upgrades to all of the major components of Rails, including a major overhaul of the router and query APIs.

One of the major achievements of this release, is that while there are loads of new features, old APIs have been deprecated with warnings wherever possible, so that you can implement the new features and conventions at your own pace. There is a backwards compatibility layer that will be supported during 3.0.x and removed in 3.1.

Rails 3.0 adds Active Model ORM abstraction, Abstract Controller generic controller abstraction as well as a consistent Plugin API giving developers full access to all the Rails internals that make Action Mailer, Action Controller, Action View, Active Record and Active Resource work.

These release notes cover the major upgrades, but don’t include every little bug fix and change. If you want to see everything,

# How would you test this Quiz#problem method? Only two rules:
#
# 1. No mocks or stubs allowed. I'm looking for a other alternatives.
# Mocks can get messy in complex scenarios, and this is intended to
# be a high level test which executes all code. I don't think mocking
# would be a very clean solution anyway, but if you want to try it
# and prove me wrong feel free.
