+# Updates — March 16, 2026
+
+## New Features
+
+### Disclaimer Page
+A new disclaimer page has been added to the application. When a disclaimer text is configured, users must read and accept it before they can start a screening. The disclaimer page renders formatted content (including headings, lists, links, and tables) and is accessible via a link on the landing page.
+
+- A checkbox appears on the landing page requiring users to agree to the disclaimer before continuing
+- The disclaimer content can be managed by administrators through the admin panel
+
+### Admin Settings Panel
+A new **Settings** section has been added to the admin panel. This provides a central place for administrators to manage application-wide content, starting with the disclaimer text. Settings are stored in the database and take effect immediately — no deployments or restarts needed.
+
+### "I Don't Know" Answer Option
+The pre-screening questionnaire now includes a third answer option: **"I don't know"**, in addition to "Yes" and "No". This gives users a more honest way to respond when they are uncertain, and is scored at half a point.
+
+### Session Duration Tracking
+The session result page now shows how long it took to complete a questionnaire. The duration is displayed in a human-readable format (e.g. "4m 32s" or "1h 15m").
+
+## Improvements
+
+### Navigation
+- A **Back button** has been added to every page in the application, making it easy to navigate to the previous step at any time
+- A **sticky Back button** appears in the top-right corner when you scroll down on longer pages, so you never have to scroll back up to navigate away
+- Visiting a page that doesn't exist now redirects you back to the landing page instead of showing an error
+
+### Disclaimer Link Behavior
+The disclaimer link on the landing page now opens in the same tab for a smoother experience.
+
+### Visual Polish
+- Removed heavy background panels from question cards and session details for a cleaner, lighter look
+- Improved the layout of session details on the result page (category, completion date, and duration are now evenly spaced)
+- Auto-save actions (answers and comments) no longer show a loading indicator, reducing visual noise while filling in questionnaires
