 ## 1.0.0
 
 Bundled with Termix 2.9.0.
+
+- Runs entirely through the plugin SDK: no imports from Termix core.
+- Remote Desktop's admin switch and guacd URL, each user's RDP defaults and
+  every host's RDP, VNC and Telnet options are this plugin's settings now,
+  moved over on upgrade.
+- The user's RDP defaults now apply to saved hosts too, not only Quick Connect.
+- Provides `sessions.live` for RDP, VNC and Telnet, so these sessions can be
+  shared and presented in collab rooms.
+- Jump host tunnels and the macOS VNC proxy close with their session instead
+  of after an hour.
+- Opening the Windows Remote Desktop client goes through the desktop app's
+  backend.
