 Highlights
 ===========================================================
 
-**Feature1**
-  Feature description.
+**Plugin framework for uploading datasets**
+  Galaxy administrators can now configure different sources
+  from which users may upload files. These include global or
+  user-specifc webdav servers, dropbox accounts as well as
+  FTP and regular filesystem locations. Developers can add
+  new types of sources by adding `PyFileSystem2 <https://docs.pyfilesystem.org/en/latest/introduction.html>`__ compatible
+  plugins. (`Pull Request 9888`_)
 
-**Feature2**
-  Feature description.
+**Workflow import from GA4GH TRS servers**
+  Galaxy can now search and import workflows from GA4GH TRS servers,
+  such as `Dockstore <https://dockstore.org/>`__ and `WorkflowHub <https://workflowhub.eu/>`__.
+  We hope that sharing workflows on these platforms will facilitate re-use and collaboration.

-**Feature3**
-  Feature description.
+**Simplified workflow submission form**
+  Galaxy now presents a simpler and cleaner interface for submitting workflows
+  that focuses on the parameters to set and datasets to choose.
+  (`Pull Request 9151`).
+
+**Accelerate batch job creation and workflow step scheduling**

+  For large batches of jobs this can speed up job creation by 100 fold or more.
