This is a big one – please try it out before we tag 2.8.0! Caddy 2.8 brings so many improvements I can’t list them here, but we encourage you to see the release notes and download:
Let us know if you encounter any issues. In particular:
- We now support ACME Renewal Information (ARI) draft spec
- Any weirdness related to ZeroSSL (please try the API too!)
- On-demand TLS improvements
- Static file serving
- Reverse proxying
If you notice anything at all, especially in those areas, please don’t hesitate to ask or report a bug. 
Thank you!
