Security
The web framework the dashboard is built on was upgraded to a version that closes a known critical security vulnerability. On the server side, the libraries used for PDFs, spreadsheets and network requests were also updated to versions with security patches. You don't need to do anything.
Guided tour
The Learn this page tour could freeze the screen on some pages. The tour no longer re-measures the page when it doesn't need to, so it now runs smoothly. Clicking a feature's description text also starts the tour for that page directly.
You can follow the system's live status on the status page.
