I am very new to using the Jevelin theme. I only bought and installed it earlier this week. Today I got an email informing me that there was an update on this theme. (I’m currently on version 4.0.1.) I want to update it to the newer version, but I’m concerned that if I do, it will overwrite the changes I’ve made so far. Can you please tell me how to update the theme version without overriding my changes?
