I'm setting up a personal website on GitHub Pages using Jekyll. I'm using the Cayman theme. I used this documentation to override some of the theme's defaults. The documentation said:
making copies of theme files will prevent you from receiving any theme updates on those files.
I'm OK with not receiving feature updates but I'm not OK with missing out on security updates. Do Jekyll themes ever receive security updates? A Google search didn't turn up anything helpful.
I don't think they do (since a Jekyll site is a static site) but I would like some input/confirmation from someone more knowledgable than myself.
