This update lets partner systems use the platform account as a way in.

Single Sign-On for Partner Systems

Third-party systems can now authenticate their users with the platform account, removing the need for a separate password in each system.

How it works:

User authorization: when signing in to the partner system, the person confirms access once.
Once authorized, the partner application receives the user’s basic identifying details.

Organization Switching from the Memberships Screen

The memberships table gained an actions column that switches between organizations right there. When a user has no membership yet, the screen now shows a message with a link to create an organization.
