* <tt>ActiveRelation#inspect</tt> no longer calls <tt>#to_a</tt>. This means that in places where <tt>#inspect</tt> is implied (such as in the console), creating a relation will not execute it anymore, you'll have to call <tt>#to_a</tt> when necessary:
* <tt>ActiveRecord::Relation#inspect</tt> now makes it clear that you are dealing with a <tt>Relation</tt> object rather than an array:
<ruby>
User.where(:age => 30) # => returns the relation
User.where(:age => 30).to_a # => executes the query and returns the loaded objects, as before
