_ [rails] 2.1.2 の render :partial 時の :locals

$ head app/views/foo/*
==> app/views/foo/_foo.html.erb <==
<%= foo_counter %>

==> app/views/foo/index.html.erb <==
<%= render :partial => "foo", :locals => {:foo_counter => 3} %>

で、2.2.2 だと

$ ruby script/console production
Loading production environment (Rails 2.2.2)
>> app.tap{|a| a.get("/foo")}.response.body
=> "3\n\n"

なんだけど、2.1.2 だと

$ ruby script/console production
Loading production environment (Rails 2.1.2)
>> app.tap{|a| a.get("/foo")}.response.body
=> "0\n\n"

なのは、がいしゅつ？

追記:pingooさんに教えていただきました。

_ [rails] FlashHash#discard

$ head app/controllers/foo_controller.rb app/views/foo/index.rhtml 
==> app/controllers/foo_controller.rb <==
class FooController < ApplicationController
  def index
    flash[:message] = "Hoge"
    flash.discard(:message)
  end
end

==> app/views/foo/index.rhtml <==
Flash: <%= flash[:message] %>

で、

$ ruby script/console production
Loading production environment.
>> RAILS_GEM_VERSION
=> "1.2.6"
>> app.tap{|a| a.get("/foo")}.response.body
=> "Flash: Hoge\n"
>> app.controller.__send__(:flash)
=> {}

だったのが、

$ ruby script/console production
Loading production environment (Rails 2.2.2)
>> app.tap{|a| a.get("/foo")}.response.body
=> "Flash: Hoge\n"
>> app.controller.__send__(:flash)
=> {:message=>"Hoge"}

だったりしてまいる。

$ ruby script/console production
Loading production environment (Rails 2.3.2)
>> app.tap{|a| a.get("/foo")}.response.body
=> "Flash: Hoge\n"
>> app.controller.__send__(:flash)
=> {}

もう 2.3.2 を使うしか？
