[Rails] Re: Rails 3.0.5 has been released!

Is anyone seeing odd errors with 3.0.5? I am seeing odd behavior
between 3.0.3 and 3.0.5. Namely, this statement...

site.featured_medias.where(:media_type => media_class, :unfeatured_at
=> nil).order("created_at desc").first

... works in 3.0.3, but produces this bad SQL in 3.0.5....

Mysql::Error: Table 'remix3_development.featured_media' doesn't exist:
SELECT `featured_media`.* FROM `featured_media` WHERE
`featured_media`.`media_type` = 'Message' AND
`featured_media`.`unfeatured_at` IS NULL AND (`featured_media`.site_id
= 1) ORDER BY created_at desc LIMIT 1

Note the table name is not pluralized. In my case, Site
has_many :featured_medias

FeaturedMedia does include a class method named featured_media, ala...

class FeaturedMedia < ActiveRecord::Base
...
def self.featured_media(site, media_class)
...
end
end

and the .where above is called within FeaturedMedia.featured_media.
