Contributions summary:Donald made several contributions to improve the functionality and stability of the Redis session store. They refactored the code by using `setex` for session expiry and removing unnecessary defaults. Further enhancements included adding custom serializer configuration, enabling the use of JSON, marshal, or hybrid serialization of session data and fixing a bug related to colliding session IDs. The user also addressed an issue allowing session changes and prepared the project for releases.
