-    "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": "* Vulnerability Protection now investigates plugins that are not distributed through\n  WordPress.org (private, premium, or vendor-hosted plugins) instead of simply reporting them as\n  unchecked. It checks the plugin's own vendor identity, changelog, and available public\n  vulnerability sources, and clearly shows what was checked, what was found, and how confident\n  the result is.\n* Added a \"Check External Intelligence\" action on the Vulnerabilities page for these plugins, plus\n  a dashboard summary of how much of your plugin inventory currently has complete vulnerability\n  coverage.\n* Findings for these plugins are now created and cleared automatically as new information becomes\n  available, the same way they already are for WordPress.org-distributed plugins.",
