rails/railties/CHANGELOG.md

*   Rails console now indicates application name and the current Rails environment:

    ```txt
    my-app(dev)> # for RAILS_ENV=development
    my-app(test)> # for RAILS_ENV=test
    my-app(prod)> # for RAILS_ENV=production
    my-app(my_env)> # for RAILS_ENV=my_env
    ```

    The application name is derived from the application's module name from `config/application.rb`.
    For example, `MyApp` will displayed as `my-app` in the prompt.

    Additionally, the environment name will be colorized when the environment is
    `development` (blue), `test` (blue), or `production` (red), if your
    terminal supports it.

*   `bin/rails` now prints its help message when given an unrecognized bare
    option.

    __Before__

      Rails 7.2.0.alpha

      $ bin/rails -V
      rake, version 13.0.6

      $ bin/rails -s

      invalid option: -S
      ```

    __After__

    *Jonathan Hefner*

*   Ensure `autoload_paths`, `autoload_once_paths`, `eager_load_paths`, and
    `load_paths` only have directories when initialized from engine defaults.
    Previously, files under the `app` directory could end up there too.

    *Takumasa Ochi*

*   Prevent unnecessary application reloads in development.

    Previously, some files outside autoload paths triggered unnecessary reloads.
    With this fix, application reloads according to `Rails.autoloaders.main.dirs`,
    thereby preventing unnecessary reloads.

    *Takumasa Ochi*

*   Use `oven-sh/setup-bun` in GitHub CI when generating an app with Bun.

    *TangRufus*

*   Disable `pidfile` generation in the `production` environment.

    *Hans Schnedlitz*

*   Set `config.action_view.annotate_rendered_view_with_filenames` to `true` in
    the `development` environment.

    *Adrian Marin*

*   Support the `BACKTRACE` environment variable to turn off backtrace cleaning.

    Useful for debugging framework code:

    ```sh
    BACKTRACE=1 bin/rails server
    ```

    *Alex Ghiculescu*

*   Raise `ArgumentError` when reading `config.x.something` with arguments:

    ```ruby
    config.x.this_works.this_raises true # raises ArgumentError
    ```

    *Sean Doyle*

*   Add default PWA files for manifest and service-worker that are served from `app/views/pwa` and can be dynamically rendered through ERB. Mount these files explicitly at the root with default routes in the generated routes file.

    *DHH*

*   Updated system tests to now use headless Chrome by default for the new applications.

    *DHH*

*   Add GitHub CI files for Dependabot, Brakeman, RuboCop, and running tests by default. Can be skipped with `--skip-ci`.

    *DHH*

*   Add Brakeman by default for static analysis of security vulnerabilities. Allow skipping with `--skip-brakeman option`.

    *vipulnsward*

*   Add RuboCop with rules from `rubocop-rails-omakase` by default. Skip with `--skip-rubocop`.

    *DHH* and *zzak*

*   Use `bin/rails runner --skip-executor` to not wrap the runner script with an
    Executor.

    *Ben Sheldon*

*   Fix isolated engines to take `ActiveRecord::Base.table_name_prefix` into consideration.
    This will allow for engine defined models, such as inside Active Storage, to respect
    Active Record table name prefix configuration.

    *Chedli Bourguiba*

*   Fix running `db:system:change` when the app has no Dockerfile.

    *Hartley McGuire*

*   In Action Mailer previews, list inline attachments separately from normal
    attachments. For example, attachments that were previously listed like

      > Attachments: logo.png file1.pdf file2.pdf

    will now be listed like

      > Attachments: file1.pdf file2.pdf (Inline: logo.png)

    *Christian Schmidt* and *Jonathan Hefner*

*   In mailer preview, only show SMTP-To if it differs from the union of To, Cc and Bcc.

    *Christian Schmidt*

*   Enable YJIT by default on new applications running Ruby 3.3+.

    Adds a `config/initializers/enable_yjit.rb` initializer that enables YJIT
    when running on Ruby 3.3+.

    *Jean Boussier*

*   In Action Mailer previews, show date from message `Date` header if present.

    *Sampat Badhe*

*   Exit with non-zero status when the migration generator fails.

    *Katsuhiko YOSHIDA*

*   Use numeric UID and GID in Dockerfile template

    The Dockerfile generated by `rails new` sets the default user and group
    by name instead of UID:GID. This can cause the following error in Kubernetes:

    ```
    container has runAsNonRoot and image has non-numeric user (rails), cannot verify user is non-root
    ```

    This change sets default user and group by their numeric values.

    *Ivan Fedotov*

*   Disallow invalid values for rails new options.

    The `--database`, `--asset-pipeline`, `--css`, and `--javascript` options
    for `rails new` take different arguments. This change validates them.

    *Tony Drake*, *Akhil G Krishnan*, *Petrik de Heus*

*   Conditionally print `$stdout` when invoking `run_generator`.

    In an effort to improve the developer experience when debugging
    generator tests, we add the ability to conditionally print `$stdout`
    instead of capturing it.

    This allows for calls to `binding.irb` and `puts` work as expected.

    ```sh
    RAILS_LOG_TO_STDOUT=true ./bin/test test/generators/actions_test.rb
    ```

    *Steve Polito*

*   Remove the option `config.public_file_server.enabled` from the generators
    for all environments, as the value is the same in all environments.

    *Adrian Hirt*
