In lib/analytical/api.rb there is a check for Rails 3.1 like so: if ::Rails::VERSION =~ /^3\.1/
if ::Rails::VERSION =~ /^3\.1/
The same Rails 3.1 codepath should probably be run for all versions > 3.1, but the check as it is will only work with 3.1.x. So Rails 3.2 executes the old path and raises a bunch of deprecation warnings.
Fixed Rails version check so it works with 3.2
