Schema_inheritance in og-0.50

I was testing the most recent testing gems for og-0.50.0 but encountered
the old schema_inheritance bug.

class Post
attr_accessor :title, String
attr_accessor :body, String

schema_inheritance

def initialize(title,body)
@title = title.to_s
@body = body.to_s
end
end

NameError: uninitialized constant Og::SchemaInheritanceBase
from /usr/lib64/ruby/gems/1.8/gems/og-0.50.0/lib/og/model.rb:531:in
`schema_inheritance’
from (irb):25

What does the future hold for schema_inheritance?
