iThemes Security Pro was updated to version 5.1.4, from version 5.1.3. Changelog:
- Enhancement: The number of users listed in the User Security Check model is now limited to 20 by default. This can be modified by using the itsec_user_security_check_users_per_page filter.
- Enhancement: Introduce Distributed Storage framework for reducing the amount of data stored in the WordPress options table. This should improve performance for large sites using File Change.
