-    "summary": "* Fixed a real bug found on a live production site right after 7.23.31 shipped: the new\n  self-health-check for the scanner and the update mechanism compared timestamps in the wrong\n  format, so it could report \"hasn't run in hours\" / \"hasn't checked in 2 days\" even seconds after\n  they genuinely had. Both are now correctly recognized as healthy when they actually are.",

+    "summary": "* Fixed a bug where a brute-force login attack that ARGUS had already blocked could keep showing\n  as an active finding and unnecessarily lower your Security Score, even though the attack was\n  already stopped. Blocked attacks are now correctly marked as automatically handled.",
