 * +CGI::Session::MemCacheStore+ has been replaced by +ActionController::Session::MemCacheStore+
 * +CGI::Session::ActiveRecordStore+ has been replaced by +ActiveRecord::SessionStore+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.
