-    "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 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.",
