A customer is using the Interface Pro theme ver 1.0.3
There’s no update available according to the wordpress dashboard.
But the latest release is ver 3.0.4.
Do we have to install the latest release manually after downloading from the themehorse account? Will the layout still be the same with the new version or what changes can we expect to do?
Yes you have to update the theme manually and there will be no any problem updating to the latest version.
For the full list of changes you can see the changelog here as well.
