Changes

• FIXED: Cancelling authentication on macOS no longer triggers an error and now correctly falls back to the configured alternative authentication method.

• FIXED: An issue preventing RealVNC Server for Linux from starting successfully when installed on a device using NFS-mounted home directories with root squash enabled.

• FIXED: RealVNC Server for Windows no longer incorrectly shows "Access Denied" for members of the Built-In Administrators group using RealVNC Server's default permissions and RADIUS authentication when Windows is configured for non-English languages.

• REMOVED: This release removes support for Windows Server 2012 and Windows Server 2012 R2.

• FIXED: The OPC license grace period now correctly allows RealVNC Server to continue functioning during temporary connectivity issues. 

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.
