Just a minor fix in A.S CHANGELOG

if a query contains a limit or an offset, ActiveRecord::FinderMethods#find_last had inconsistent behavior.

If the records were loaded, it returned the last record in the cached list.
If they were not, it reversed the order of the query and changed the limit to one.
If the earlier limit was less than the total matching the query in the db,
it would return a different record than if the records had been cached.

This commit changes find_last so that it loads the records when getting the
last record on a query containing a limit or an offset, which makes the behavior consistent.

Ensure that ORDER BY clauses from default scopes are not included in calculation queries. Fixes #406.

indifferent access should recurse Hash subclasses

This commit makes Hash subclasses convert to HWIA by default for nested
objects of subclasses of Hash, but allows certain subclasses to prevent nested
conversion by introducing Hash#nested_under_indifferent_access that subclasses
can overwrite.

ActiveSupport::OrderedHash is one such subclass that overwrites
+nested_under_indifferent_access+, since implicitly converting it to HWIA would
remove the ordering of keys and values in Ruby 1.8.

This change is necessary because commit ce9456ec broke nested indifferent access
conversion for all subclasses of Hash.
