- Added load‑balancing with round‑robin, Cassandra 3.x support, WebSocket upgrades, internal DNS (A/SRV) resolution, and flexible routing (host, path, method) plus new /upstreams and /targets APIs.
- Introduced dynamic SSL in core (removed SSL plugin), dropped TLS 1.0 and Dnsmasq, enforced no trailing slash in upstream URLs, and added stronger SHA‑256 RSA certificate generation.
- Breaking changes to Admin API routing fields (request host/uri no longer supported) require migration and updated proxy guide; documentation revised accordingly.
