Rails 5.0！Rails 团队前几天刚刚庆祝 Rails 1.0发布十周年，现在只是测试版本， 但是 Rails 5.0.0.beta1 已经在生产环境运行 Basecamp 3。
Rails 5.0 Beta1 版本主要改进：全新处理 WebSockets 框架 Action Cable；新 API 模式 --api；Rails 命令都提供在 bin/rails 。
其他值得关注的新特性：
- New Attributes API by Sean Griffin.
- The test runner now reports failures inline, so you don't have to complete the suite to see what went wrong.
- ApplicationRecord has been born as a default parent class of all models created by the generators.
- ActiveRecord::Relation#in_batches makes it much easier to deal with record work in batches at a time to lessen memory overloads.
- Post.where('id = 1').or(Post.where('id = 2')) gives you exactly what you'd think!
- No more accidentally halting Active Record callbacks because the last statement is false. Now you throw(:abort) explicitly!
