A few days ago Gulden.com released an update for their desktop wallets. Next to some solved bugs and improvements, the new brand colors are now used. As is the new Gulden logo.
Download the new version here.
Before updating, stop the desktop Gulden application, download, overwrite and start the application again.
The update is also available for the raspbian Pi’s, for those who run Witness wallets and Full Nodes.
For them, in G-Dash go to Settings->Debug Console and type Guldenstop. Then pull the plug for a few seconds and let the Pi reboot again. The update will load automatically.
