Manage your data updates with the recently added Update manager.
The Update manager assists in updating data provided by the plugins, not the plugin themselves.
First one out is the GeoNames search engine database, which is no longer bundled with Mapton, instead, you will be prompted to install it if it’s missing and update if it’s old. As a result of that, the mapton.zip got reduced from 61 to 55 MB. 🙂
This is part of the Mapton API available to plugin developers.
