I've put on a fresh code of paint on my personal blog (https://batsov.com/) today. I've been using #Jekyll for ages and today I've switched from the Minimal Mistakes theme to Chirpy.
Normally I do such theme changes manually, but in line with the times I've opted to delegate the update to an AI agent. I have to give it to #ClaudeCode - it handled theme update quite well overall and it even fixed some inconsistent tags I had used over the years.
