# Changelog
## 2026-02-16 - 25.5.0 - feat(tls)
add shared TLS acceptor with SNI resolver and session resumption; prefer shared acceptor and fall back to per-connection when routes specify custom TLS versions
- Add CertResolver that pre-parses PEM certs/keys into CertifiedKey instances for SNI-based lookup and cheap runtime resolution
- Introduce build_shared_tls_acceptor to create a shared ServerConfig with session cache (4096) and Ticketer for session ticket resumption
- Add ArcSwap<Option<TlsAcceptor>> shared_tls_acceptor to tcp_listener for hot-reloadable, pre-built acceptor and update accept loop/handlers to use it
- set_tls_configs now attempts to build and store the shared TLS acceptor, falling back to per-connection acceptors on failure; raw PEM configs are still retained for route-level fallbacks
- Add get_tls_acceptor helper: prefer shared acceptor for performance and session resumption, but build per-connection acceptor when a route requests custom TLS versions
## 2026-02-16 - 25.4.0 - feat(rustproxy)
support dynamically loaded TLS certificates via loadCertificate IPC and include them in listener TLS configs for rebuilds and hot-swap
