RailsConfig v4.0.0 Release Notes


    • ๐Ÿ’Ž Rails versions < 5.2 are no longer supported (#316)
    • ๐Ÿ’Ž Ruby versions < 2.6 are no longer supported (#316)
    • Support HashSource and EnvSource instances in Config.load_files and Config.load_and_set_settings. (#315). There are a few subtle breaking changes:
      • Previously, Config.load_files (called from Config.load_and_set_settings) would call .to_s on each of its arguments. Now, this responsibility is defered to YAMLSource. In effect, if your application passes String or Pathname objects to Config.load_files, no changes are necessary, but if you were somehow relying on the .to_s call for some other type of object, you'll now need to call .to_s on that object before passing it to Config.
      • Before this change, Config.load_files would call uniq on its argument array. This call has been removed, so duplicate file paths are not removed before further processing. In some cases, this can cause differences in behavior since later config files override the values in earlier ones. In most cases, it's best to ensure that duplicate paths are not passed to Config.load_files.
