 - 📝 **Misc**
   - Minor adjustments to documentation and configuration files.
-  - Switched test dependency to `pytest` for a more modern testing workflow.
-  - Redis client factories changed from lambdas to named functions for better type checking and extensibility.
-  - In `utils.py`, branches for missing `pygments` are now marked with `# pragma: no cover` to improve coverage reporting.

 Other serialization libraries such as [bson][], [simplejson](https://pypi.org/project/simplejson/), [cJSON](https://github.com/DaveGamble/cJSON), [msgpack][], [yaml][], and [cloudpickle](https://github.com/cloudpipe/cloudpickle) are also supported.

 > The [`pickle`][] module is highly powerful but poses a significant security risk because it can execute arbitrary code during deserialization. Use it with extreme caution, especially when handling data from untrusted sources.
 > For best practices, it is recommended to cache functions that return simple, [JSON][]-serializable data. If you need to serialize more complex data structures than those supported by [JSON][], consider using safer alternatives such as [bson][], [msgpack][], or [yaml][].
