+## Preservation of default settings for new repositories
+
+If you had default security settings in place for newly created repositories, {% data variables.product.github %} will preserve these settings by automatically creating a "New repository default settings" {% data variables.product.prodname_security_configuration %} for your enterprise. The configuration matches your previous enterprise-level default settings for new repositories as of December 2024.
