 ## [Unreleased]
 
+- Support `performs` on private methods
+
+  Method jobs will now call methods with `send`, in case you only want to expose the generated later method to the outside world.
+
+  ```ruby
+  class Post < ActiveRecord::Base
+    performs :something_low_level
+
+    private
+
+    # We don't want other objects to call this, they should always use the generated later method.
+    def something_low_level
+      # …
+    end
+  end
+  ```
+
+  Here, the generated `Post#something_low_level_later` is public and available but can still call into the immediate version of `something_low_level`.
+
 ## [0.1.1] - 2022-09-27
 
 - Fixed: extend ActiveRecord::Base with ActiveJob::Performs as the README says.

+#### Private methods
+
+`ActiveJob::Performs` also works with private methods in case you only want to expose the generated `_later` method.
+
+```ruby
+class Post < ActiveRecord::Base
+  performs :publish # Generates the public `publish_later` instance method.
+
+  # Private implementation, only call `publish_later` please!

 ### Usage with ActiveRecord::AssociatedObject
 
 The [`ActiveRecord::AssociatedObject`](https://github.com/kaspth/active_record-associated_object) gem also implements `GlobalID::Identification`, so you can do this too:
