This update introduces a common way to plan, assign, and complete follow-up activities such as calls, emails, and meetings directly on business records. It brings the feature into CRM, invoicing, recruitment, maintenance, manufacturing, repairs, and contacts, while also improving privacy behavior so external users are not subscribed to internal-only updates by default.
