+
+### Added
+
+- Settings may be specified with a `cloneable` option, e.g.
+
+```ruby
+setting :component_dirs, Configuration::ComponentDirs.new, cloneable: true
+```
+
+This change makes it possible to provide “rich” config values that carry their own
+configuration interface.
+
+In the above example, `ComponentDirs` could provide its own API for adding component
+dirs and configuring aspects of their behavior at the same time. By being passed to
+the setting along with `cloneable: true`, dry-configurable will ensure the setting's
+values are cloned along with the setting at all the appropriate times.
+
+A custom cloneable setting value should provide its own `#initialize_copy` (used by
+`Object#dup`) with the appropriate logic. (@timriley in #102)
+
+### Fixed
+
+- Only `#initialize` instance method is prepended, leaving the rest of the instance
+methods to be included as normal again. This allows classes including
+`Dry::Configurable` to override instance methods with their own methods as required
+(@adam12 in #103)
