-    "summary": "* Added a way to download your MFA backup codes as a file right after they're generated, so you\n  don't have to copy them down by hand. You can optionally protect the file with your own\n  passphrase -- it's encrypted in your browser before saving, and a matching offline tool (linked\n  from the same page) lets you read it back later even if you can't reach your site's admin area.\n* Fixed an edge case in Safe Mode (the wp-config.php recovery switch) where a fresh security event\n  happening while Safe Mode was on could still block the request -- Safe Mode now reliably means no\n  blocking at all, matching what it has always said it does.",

+    "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.",
