+**New Features**
+
+-  WebUI: In the Experimental features, Flat Runs View is now "on" by default in the :ref:`WebUI
+   <web-ui-if>`\. Users can still toggle this feature "off".
+-  This update improves the ability to compare model performance between different trials, based on
+   user feedback that most Determined users run single-trial experiments.
+-  "Experiments" is now renamed to "searches" and "trials" is now renamed to "runs" for better
+   clarity.
+-  The "experiment list" is renamed the "run list", showing all trials from experiments in the
+   project. It functions similarly to the previous new experiment list.
+-  Multi-trial experiments can be viewed in the new searches view, which allows for sorting,
+   filtering and navigating multi-trial experiments.
+-  When viewing a multi-trial experiment, a list of trials is displayed, allowing for sorting,
+   filtering and arbitrary comparison between trials.
