+### Analyzers in Web Interface
+
+A new menu item _ANALYZERS_ has been added to the side navigation bar of the
+Web UI. Through this page, you can view existing Analyzers as well create new
+Analyzers. The UI is full-featured and lets you feed in all parameters and
+options that you could otherwise input through the HTTP or JavaScript API.
+
+It also lets you copy configuration from an existing Analyzer, allowing for a
+much quicker workflow when your new Analyzer is very similar to an existing one.
+
+It offers two edit/view modes - a form mode where a standard web form is used to
+capture user input, and a JSON mode where experienced users can directly write
+the raw Analyzer configuration in JSON format.
+
+### Configurable root redirect
+
+Added two options to `arangod` to allow HTTP redirection customization for
+root (`/`) call of the HTTP API:
+
+- `--http.permanently-redirect-root`: if `true` (default), use a permanent
+  redirection (use HTTP 301 code), if `false` fall back to temporary redirection
+  (use HTTP 302 code).
+
+- `--http.redirect-root-to`: redirect of root URL to a specified path.
+  Redirects to `/_admin/aardvark/index.html` if not set (default).
+
+These options are useful to override the built-in web interface with some 
+user-defined action.
+
+### Web interface session handling
+
+The previously inactive startup parameter `--server.session-timeout` was
+revived and now controls the timeout for web interface sessions (and other
+sessions that are based on JWTs created by the `/_open/auth` API).
+
+For security reasons, the default timeout value for web interface sessions
+has been reduced to one hour, after which a session is ended automatically.
+Web interface sessions that are active (i.e. that have any user activity)
+are automatically extended until the user ends the session explicitly or
+if there is a period of one hour without any user activity.
+
+The timeout value for web interface sessions can be adjusted via the
+`--server.session-timeout` startup parameter (in seconds).

 in the RocksDB block cache. This is useful for queries that read a lot of (cold)
 data which would lead to the eviction of the hot data from the block cache.
