Hugo Workflow Question

My Site/It’s repo

I’m using the ananke theme as a hugo module and I have mildly modified a few files which override the theme’s versions. Couple of questions:

  1. The ananke theme does releases on github. Last release was June 2022 but there have been commits on the main branch since then. Do hugo modules match the latest release or simply head in their repo?
  2. If you have modified theme files, what is the recommended workflow as changes to the theme are comitted in git?
