This release provides security patches and these enhancements:
If you sign in to Domino through SSO, Domino now signs out when you close your browser session. After closing the browser session, you must sign in to Domino again. This new behavior doesn’t impact local logins.
Now, when you click Log Out, Domino consistently enforces sign-out, even if you return immediately to Domino in the same browser tab or window.
