 ### Changed
 
 - `by_period` uniqueness is now based off a job's `scheduled_at` instead of the current time if it has a value. [PR #39](https://github.com/riverqueue/riverqueue-ruby/pull/39).
 
+## Fixed
+
+- Correct some mistakes in the readme that referenced `SimpleArgs` instead of `SortArgs`. [PR #44](https://github.com/riverqueue/riverqueue-ruby/pull/44).

 ## [0.8.0] - 2024-12-19
 
 ⚠️ Version 0.8.0 contains breaking changes to transition to River's new unique jobs implementation and to enable broader, more flexible application of unique jobs. Detailed notes on the implementation are contained in [the original River PR](https://github.com/riverqueue/river/pull/590), and the notes below include short summaries of the ways this impacts this client specifically.
