# Changelog

## June 18, 2026

* Rebuilt buffer.lol as a public diagnostics toolbox for network, IP, web, and developer checks.
* Added browser-local utilities for JSON, Base64, hashing, UUIDs, timestamps, URL parsing, JWT decoding, regex testing, CIDR math, and user-agent inspection.
* Added same-origin diagnostics API requests at `POST /api/tools/[slug]`.
* Added server-backed checks for DNS records, HTTP headers, TLS certificates, uptime, TCP ports, public IP, IP geolocation/network data, ASN data, RDAP lookups, redirects, and robots/sitemap discovery.
* Marked ping, packet-loss, and traceroute as worker-required tools until ICMP and traceroute support can run in a container or VM worker.
