- Sitemap endpoint now recursively expands sitemap-index files - Fixes #165 - Strips :port from target URLs in get-ip, dns, dns-server, ports, mail-config - Fixes #203 - Configurable trust proxy (TRUST_PROXY env) so app works behind Traefik/nginx - Fixes #157 - Tranco rank now correctly says "top 1 million" (was "100 million") - Fixes #257 - Adds engines.node ">=20" so Vercel picks a supported runtime - Re #212 - Raises Vercel maxDuration from 10s to 60s, cutting most 504 timeouts - Re #251 - Re #287 - Bumps axios 1.4.8 to 1.16, closing 4 high-severity SSRF/DoS CVEs - Re #289 - Fixes mail-config crash where dns module was awaited as if promise-based - Adds reusable structured logging util for the API - Bumps a whole bunch of deps, and resolves lots of open npm CVEs
