+<h2>Release 5.9.1</h2>
+<p>This release updates the build system in use for EDMC to a more feature-rich installer, as well
+as updating the commodity information to be up-to-date for Update 16.</p>
+<p>NOTE: This version hands over the installer to an EXE file for Windows instead of an MSI.
+This does not change any functionality or plugin capability of EDMC. You may need to
+manually close EDMC during the update process if updating from version 5.9.0 or earlier.</p>
