Eighteen new lessons cover law and privacy, investigations, personnel and supply chain security, awareness training, threat modeling, cryptanalysis, cloud and industrial systems, facility security, the system lifecycle, wireless and cellular networks, network access control and endpoints, acquired and open-source software, logging and monitoring, change and patch management, operations controls and physical safety. The question bank grows to 383, flashcards to 138 and PBQ-style activities to 15. Incident management now follows the seven steps in the CISSP outline, the NIST RMF includes Prepare, OWASP content uses the 2025 Top 10, and sanitization and incident response references cite the current NIST revisions. The glossary now spells out terms without repeating paid flashcards. Questions and flashcards that were rewritten start fresh in spaced review. Fixes: your streak no longer reads 0 each morning, exam reminders count down day by day, the Home suggestion opens the domain it names, and buttons in timed practice and PBQs have VoiceOver labels.
