-    "summary": "* Hardened the optional page cache: cached pages can no longer be reached directly as raw files --\n  every request still goes through ARGUS's normal security checks, including an active IP block,\n  before anything is served.\n* Fixed a rare timing issue where, under heavy simultaneous traffic to the same page right as its\n  cache was refreshing, a visitor could in theory receive an incomplete page. Cache updates are now\n  published in a single, all-or-nothing step.",
+    "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.",
