 ## [Unreleased] - Development
 
+## [1.4.12]
+### Added
+- Webui :       Show wifi ssid scan
+                additional input for timeout to reset if network reconnect failed
+                refactoring and change layout of buttons
+                dock-menu (drag-n-drop)
+- Network :     wifi ssid scan added
+### Fixed
+- network :     reconnect network if dhcp server is not working at reset from vdmot
+                timeout for reset if network reconnect failed (power on behaviour)
+- update WTH :  reset delay after update to show website correct (seen with wifi connection)
+
 ## [1.4.10]
 ### Added
 - Webui :       Show information if stm failed
