Improved security protections

This release includes additional security hardening to help protect against unauthorised code being loaded into the application on Windows systems.

By default, the application will now only load trusted, Microsoft‑signed system components, reducing the risk of malicious software interfering with the application at runtime.

This protection is enabled automatically. In rare cases where compatibility issues are encountered, it can be disabled using the RestrictedMode=0 setting. For more information, please see our Help Center article here.
