Corresponding rake tasks added as well. + +* Set a different cache per environment for assets pipeline through `config.assets.cache`. + +* `Rails.public_path` now returns a Pathname object. + +* Remove highly uncommon `config.assets.manifest` option for moving the manifest path. This option is now unsupported in sprockets-rails. + +* Add `config.action_controller.permit_all_parameters` to disable StrongParameters protection, it's false by default. + +* Remove `config.active_record.whitelist_attributes` and `config.active_record.mass_assignment_sanitizer` from new applications since MassAssignmentSecurity has been extracted from Rails. + +* Change `rails new` and `rails plugin new` generators to name the `.gitkeep` files as `.keep` in a more SCM-agnostic way.

With this behavior, you *should not* use default_url_options[:script_name] to set proper application's mount point by yourself. + +* `config.threadsafe!` is deprecated in favor of `config.eager_load` which provides a more fine grained control on what is eager loaded. + +* The migration generator will now produce AddXXXToYYY/RemoveXXXFromYYY migrations with references statements, for instance + + rails g migration AddReferencesToProducts user:references supplier:references{polymorphic} + + will generate the migration with: + + add_reference :products, :user, index: true + add_reference :products, :supplier, polymorphic: true, index: true + * Allow scaffold/model/migration generators to accept a `polymorphic` modifier for `references`/`belongs_to`, for instance ``` |
