Unboxing Rails 7What's new in the latest major version
summary
Rails 7 removes webpacker and spring from the default stack and ships new generators for JS and CSS bundling so apps can pick ESBuild Rollup or Webpack or use import maps and Hotwire as the no‑bundle default; import maps work for plain JS and Hotwire but not for JSX React without a compiler. Active Record gains encrypted attributes that remain queryable and a load_async API for background query execution. Over 4,000 commits by ~500 contributors land these changes.
