Pay attention to the End of Engineering (EoE) notice buried in the notes:
While previous versions relied on cloud lookups, 11.0 enhances the Inline Machine Learning (ML) engine. The firewall now blocks never-before-seen (Zero-Day) evasive command-and-control traffic directly in the data path without a signature update.
Gone are the days of separate agents. PAN-OS 11.0 deeply integrates AIOps directly into the management plane. The firewall now proactively identifies misconfigurations, capacity bottlenecks, and software bugs before they cause an outage.
