+### Detached scheduler threads
+
+<small>Introduced in: v3.11.5</small>
+
+A scheduler thread now has the capability to detach itself from the scheduler
+if it observes the need to perform a potentially long running task, like waiting
+for a lock. This allows a new scheduler thread to be started and prevents
+scenarios where all threads are blocked waiting for a lock, which has previously
+led to deadlock situations.
+
+Threads waiting for more than 1 second on a collection lock will detach
+themselves.

+### Unified list view
+
+ArangoDB 3.12 brings a significant enhancement to the display of collections,
+Views, graphs, users, services, and databases in the web interface.
+The previous tile format has been replaced with a user-friendly tabular
+layout, providing a consistent and intuitive experience that is visually
+aligned across all components. The existing tabular views have also been
+reworked to ensure a seamless transition.
+
+The new tabular format includes the following features:
+- **Dynamic filters on columns**: Each column now has a dynamic filter box,
+  allowing you to efficiently search and filter based on keywords. This makes
+  it easy to locate specific items within the list.
+- **Dynamic sorting on columns**: Sort elements easily based on column data
+  such as name, date, or size. This functionality provides a flexible way to
+  organize and view your data.
