Beta3 adds metrics and observability support, renders the docs guides into the website, and includes build and packaging fixes.
MetricsFile — Prometheus textfile exporter: PhoenixDKIM writes a Prometheus-format counters file to the node_exporter textfile collector directory. No extra library or daemon required; switched on by setting MetricsFile in phoenixdkim.conf.
StatsDHost — UDP StatsD exporter for Graphite / InfluxDB pipelines.
LogResults — structured per-message log line with signing / verification outcome, algorithm, key size, and domain.
The guides in docs/ are now rendered into the website and served as the authoritative reference — Quick Start, Key Rotation, Removed Features, Crypto Policy, Multisigning, and the new Metrics guide. The website build now warns on dead internal links.
Lua version requirement relaxed to >= 5.4 (was exactly 5.4); fixes builds on distributions shipping Lua 5.5 such as Fedora Rawhide.
