* +CGI::Session::MemCacheStore+ has been replaced by +ActionController::Session::MemCacheStore+
* +CGI::Session::ActiveRecordStore+ has been replaced by +ActiveRecord::SessionStore+
* You can still change your session store with +ActionController::Base.session_store = :active_record_store+
* Default sessions options are still set with +ActionController::Base.session = { :key => "..." }+
* Default session options are still set with +ActionController::Base.session = { :key => "..." }+. However, the +:session_domain+ option has been renamed to +:domain+.
* The mutex that normally wraps your entire request has been moved into middleware, +ActionController::Lock+
* +ActionController::AbstractRequest+ and +ActionController::Request+ have been unified. The new +ActionController::Request+ inherits from +Rack::Request+. This affects access to +response.headers['type']+ in test requests. Use +response.content_type+ instead.
* +ActiveRecord::QueryCache+ middleware is automatically inserted onto the middleware stack if +ActiveRecord+ has been loaded. This middleware sets up and flushes the per-request Active Record query cache.
