There is an update available for the. Hydra theme.  According to a link on the themes update page, you should use child themes to upgrade a theme.  This is recommended for those who have “modified” the theme.

I have not modified my theme in any way.  However, i did customize my theme.. made different choices … color scheme, link locations, etc.

If I upgrade Hydra, will i lose my customizations if I don’t use a child theme?
