This is a new release candidate of Caddy 2.2, meaning we think it’s good enough to release but we want you to double-check before the final tag! Thank you to all who tried the first release candidate and provided constructive feedback; we think RC3 is much improved!
(RC3 is a hotfix for RC2. Don’t use RC2, heh.)
This pre-release adds support for Prometheus metrics. Thanks @hairyhenderson for that!
Release notes and Download 
Work is ongoing to reduce Caddy binary sizes and to improve build reliability. We’re trying to eliminate dependencies, but most of them are very indirect and will require cooperation with or replacing upstream libraries (as we did with lego → ACMEz).
At this point, we hope to continue improving documentation + filling out our community wiki (you can help!) as work begins on the next major project: remote fleet management and admin UI.
