Rails 5.1.2.rc1 (June 20, 2017)

  • Add Windows support to rails secrets:edit.

    Kasper Timm Hansen

Rails 5.1.1 (May 12, 2017)

  • No changes.

Rails 5.1.0 (April 27, 2017)

  • Namespace error pages' CSS selectors to stop the styles from bleeding into other pages when using Turbolinks.

    Jan Krutisch

  • Raise a error when using a bad symlink

    Previously bad symlinks (where the link destination doesn't exist) would be silent ignored and lead to hard to diagnose problems as the non-existence isn't readily apparent.

    Richard Schneeman

  • Remove -j (--javascript) option from rails new command.


  • Specify form field ids when generating a scaffold.

    This makes sure that the labels are linked up with the fields. The regression was introduced when the template was switched to form_with.

    Yves Senn

  • Add app:update task to engines.

    Yuji Yaginuma

  • Avoid running system tests by default with the bin/rails test and bin/rake test commands since they may be expensive.

    Fixes #28286.

    Robin Dupret

  • Improve encryption for encrypted secrets.

    Switch to aes-128-gcm authenticated encryption. Also generate a random initialization vector for each encryption so the same input and key can generate different encrypted data.

    Double the encryption key entropy by properly extracting the underlying bytes from the hexadecimal seed key.

    NOTE: Since the encryption mechanism has been switched, you need to run this script to upgrade:

    Stephen Touset

  • Add encrypted secrets in config/secrets.yml.enc.

    Allow storing production secrets straight in the revision control system by encrypting them.

    Use bin/rails secrets:setup to opt-in by generating config/secrets.yml.enc for the secrets themselves and config/secrets.yml.key for the encryption key.

    Edit secrets with bin/rails secrets:edit.

    See bin/rails secrets:setup --help for more.

    Kasper Timm Hansen

  • Fix running multiple tests in one rake command

    e.g. bin/rake test:models test:controllers

    Dominic Cleal

  • Add option to configure Ruby's warning behaviour to test runner.

    Yuji Yaginuma

  • Install Byebug gem as default in Windows (mingw and x64_mingw) platform.

    Junichi Ito

  • Make every Rails command work within engines.

    Sean Collins, Yuji Yaginuma

  • Don't generate HTML/ERB templates for scaffold controller with --api flag.

    Rafael Mendonça França

    Rafael Mendonça França

  • Remove deprecated config.static_cache_control.

    Rafael Mendonça França

  • The log:clear task clear all environments log files by default.

    Yuji Yaginuma

  • Add Webpack support in new apps via the --webpack option, which will delegate to the rails/webpacker gem.

    To generate a new app that has Webpack dependencies configured and binstubs for webpack and webpack-watcher:

    rails new myapp --webpack

    To generate a new app that has Webpack + React configured and an example intalled:

    rails new myapp --webpack=react


  • Add Yarn support in new apps with a yarn binstub and package.json. Skippable via --skip-yarn option.

    Liceth Ovalles, Guillermo Iguaran, DHH

  • Removed jquery-rails from default stack, instead rails-ujs that is shipped with Action View is included as default UJS adapter.

    Guillermo Iguaran

  • The config file secrets.yml is now loaded in with all keys as symbols. This allows secrets files to contain more complex information without all child keys being strings while parent keys are symbols.

    Isaac Sloan

  • Add :skip_sprockets to Rails::PluginBuilder::PASSTHROUGH_OPTIONS

    Tsukuru Tanimichi

  • Add --skip-coffee option to rails new

    Seunghwan Oh

  • Allow the use of listen's 3.1.x branch

    Esteban Santana Santana

  • Run Minitest.after_run hooks when running rails test.

    Michael Grosser

  • Run before_configuration callbacks as soon as application constant inherits from Rails::Application.

    Fixes #19880.

    Yuji Yaginuma

  • A generated app should not include Uglifier with --skip-javascript option.

    Ben Pickles

  • Set session store to cookie store internally and remove the initializer from the generated app.

    Prathamesh Sonpatki

  • Set the server host using the HOST environment variable.


  • Add public API to register new folders for rake notes:

    config.annotations.register_directories('spec', 'features')

    John Meehan

  • Display name of the class defining the initializer along with the initializer name in the output of rails initializers.

    Before: disable_dependency_loading

    After: DemoApp::Application.disable_dependency_loading


  • Do not run bundle install when generating a new plugin.

    Since bundler 1.12.0, the gemspec is validated so the bundle install command will fail just after the gem is created causing confusion to the users. This change was a bug fix to correctly validate gemspecs.

    Rafael Mendonça França

  • Ensure /rails/info routes match in development for apps with a catch-all globbing route.

    Nicholas Firth-McCoy

  • Added a shared section to config/secrets.yml that will be loaded for all environments.
