Upgrade information{#flow-designer-rn__flow-designer-rn-upgrade-info}

:   The Brazil release introduces enhanced protections for read‑only fields across the ServiceNow AI Platform®. These changes include a new "read_only_option" field with granular control levels, including "strict_read_only" and "client_script_modifiable". The changes occur in the back end and maintain backward‑compatible behavior. This update helps strengthen your instance security while preserving the flexibility you need. Refer to [KB2718122](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2718122) for additional technical details on how to identify affected fields and adjust their settings. For more information about granular read-only security options, see [Configuring read-only security options](https://www.servicenow.com/docs/access?context=read-only-option&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).
