Every Mt. Mograph plugin comes with a Lifetime License that includes free updates forever. In this menu panel you have the option to download and install updates automatically or manually.
When enabling the auto-update system newly available updates will automatically be downloaded and installed on startup. You will still be prompted to enter your password to finalize the installation. If you don't enable the auto-update system a Release button will appear on this page when new updates are available. You can click on this button to download and install the update.
