-    "summary": "* Fixed the new mobile navigation strip so it's clear there are more sections to scroll to -- it\n  only showed the first few before.\n* Fixed a real cross-browser rendering issue that could make the \"Blocked Requests\" chart appear\n  completely blank on some phones/browsers.\n* The Security Score card is now a clickable link straight to your Findings, and MFA backup codes\n  now display correctly on small screens.\n* Vulnerability status and Firewall Rule Activity now use donut charts and a compact \"all clear\"\n  indicator, consistent with the rest of the dashboard.",

+    "summary": "* Fixed: right after ARGUS checked for updates, its own health check could momentarily read that\n  timestamp before it was refreshed and report \"hasn't checked for updates\" -- the two checks now\n  run in the correct order.\n* The health-check findings for scanner/update/intelligence timing now explain the most common\n  real cause specifically -- WordPress's own scheduled-task system (WP-Cron) not firing reliably,\n  common on low-traffic sites or hosts without a real system cron configured -- instead of a\n  generic \"contact support.\"",
