+
+##### Mendix Workstation Management is available for all Mendix users
+

+It is not possible to add a member to a workspace owned by a user belonging to a company not entitled to a Mendix Workstation Client license.
+

+
+*   Quit Workstation Client is not available in non-developer mode.
+*   Unlink Workstation Client is not available in non-developer mode.
+*   Developer tool shortcut is not available in non-developer mode.
+

+

+
+The Mendix Workstation Client Sample App showcases how to build applications interacting with multiple peripheral devices.
+
+The app includes reusable peripheral modules for:
+

+    *   e.g. Omnikey 5427 G2, ACR122U
+*   Barcode Scanner (configured on Serial Port)

+*   Label Printer (ZPL protocol)
+    *   e.g. Zebra ZD421D
+*   USB Andon tower / Stack light
+    *   e.g. ANDONT USB Stack LED Andon Tower Lights
+
+Each module includes a peripheral emulator to build apps without a physical device.
+
+The Sample App is available in the marketplace.
+
+#### Improvements
+
+##### Workstation Management
+
+*   Addition of the Mendix Portal Global Navigation Menu top bar and menu.
+*   Usability improvements.
+
+##### Workstation Client
+
+*   Add a button to paste the registration token.
+
+##### Workstation Connector
+
+*   The security role `SecurityAdministrator` is added: only users with this role can Regenerate KeyPair in Station connector Security of an App.
+
+#### Fixes
+
+We fixed an issue in Workstation Client where, when the client app closed and re-opened a connection, data buffered from the previous session was sent to the new session. The data buffer now is cleared when the connection is closed.
