**********
- **Session Library:** The session initialization debug message now uses the correct log type "debug" instead of "info".

- **Validation:** Fixed the `getValidated()` method that did not return valid data when validation rules used multiple asterisks.

See the repo's
`CHANGELOG.md <https://github.com/codeigniter4/CodeIgniter4/blob/develop/CHANGELOG.md>`_
for a complete list of bugs fixed.
