Rails Rails 4.0.0.beta 来了。。。
dhh 说 rails 3.x 到 rails 3.2.x 为止就不往后了，现在 rails 已经在开发 rails 4.0 了，只支持 ruby 1.9.3 以上。。。
“ We’re simply doing this now because we’re dropping support for Ruby 1.8.7 in rails/master and people should know what’s up.”
https://github.com/rails/rails/pull/505 这个 pull request 已经吵了很久了 4.0 一定会增加 patch verb 哇卡卡
