Sometimes I took long walks on the plateau with a station friend, a carpenter. One night, short on time and exhausted from a twelve-mile walk in the mild fifteen-below air, I pawed through the pantry for something easy to bake, cringing at the boxes of Duncan Hines Devil’s Food Cake Mix and generic no-bake cheesecake. Thinking that I might risk cheating my way into a cherry pie, I picked up a box of Gold Medal Deluxe Instant Pie Crust.

3.4最易忽略的变更：捆绑gem调整。base64、csv、bigdecimal等不再作为默认gem。未在Gemfile声明而直接调用require 'csv'的代码将触发LoadError，且错误信息不会提示版本升级原因。早期Rails应用（特别是4.x/5.x时期）常存在对此类gem的隐式依赖。若经由3.3过渡，将提前获得明确警告。
