 # Vaadin 8 extended maintenance version changelog

+* Added Read-Only mode support to Grid and Compatibility Grid.
+  The Read-Only mode can be engaged using the *existing* API
+  call `grid.setReadOnly(true)`. This mode disallows
+  editing of the Grid, while still allowing scrolling. This was

+  classes had to be done through magic strings in the application.
+* Fixed an issue with `DateField` event propagation when the
+  backend doesn't immediately service the request. Events would
+  get queued and then sent stale and out of order, resulting in
+  the server side getting false user interaction events from
+  the `DateField`.
+* Updated `jetty` dependency to address CVE-2023-36479.
