 # Changelog
 
+## 2026-02-19 - 25.7.5 - fix(rustproxy)
+prune stale per-route metrics, add per-route rate limiter caching and regex cache, and improve connection tracking cleanup to prevent memory growth
+
+- Prune per-route metrics for routes removed from configuration via MetricsCollector::retain_routes invoked during route table updates
+- Introduce per-route shared RateLimiter instances (DashMap) with a request-count-triggered periodic cleanup to avoid stale limiters
+- Cache compiled URL-rewrite regexes (regex_cache) to avoid recompiling patterns on every request and insert compiled regex on first use
+- Improve upstream connection tracking to remove zero-count entries and guard against underflow, preventing unbounded DashMap growth
+- Evict per-IP metrics and timestamps when the last connection for an IP closes so per-IP DashMap entries are fully freed
+- Add unit tests validating connection tracking cleanup, per-IP eviction, and route-metrics retention behavior
+
+## 2026-02-19 - 25.7.4 - fix(smart-proxy)
+include proxy IPs in smart proxy configuration
+
+- Add proxyIps: this.settings.proxyIPs to proxy options in ts/proxies/smart-proxy/smart-proxy.ts
+- Ensures proxy IPs from settings are passed into the proxy implementation (enables proxy IP filtering/whitelisting)
+
+## 2026-02-16 - 25.7.3 - fix(metrics)
+centralize connection-closed reporting via ConnectionGuard and remove duplicate explicit metrics.connection_closed calls
+
+- Removed numerous explicit metrics.connection_closed calls from rust/crates/rustproxy-http/src/proxy_service.rs so connection teardown and byte counting are handled by the connection guard / counting body instead of ad-hoc calls.
+- Simplified ConnectionGuard in rust/crates/rustproxy-passthrough/src/tcp_listener.rs: removed the disarm flag and disarm() method so Drop always reports connection_closed.
+- Stopped disarming the TCP-level guard when handing connections off to HTTP proxy paths (HTTP/WebSocket/streaming flows) to avoid missing or double-reporting metrics.
+- Fixes incorrect/duplicate connection-closed metric emission and ensures consistent byte/connection accounting during streaming and WebSocket upgrades.
+
+## 2026-02-16 - 25.7.2 - fix(rustproxy-http)
+preserve original Host header when proxying and add X-Forwarded-* headers; add TLS WebSocket echo backend helper and integration test for terminate-and-reencrypt websocket
+
+- Preserve the client's original Host header instead of replacing it with backend host:port when proxying requests.
+- Add standard reverse-proxy headers: X-Forwarded-For (appends client IP), X-Forwarded-Host, and X-Forwarded-Proto for upstream requests.
+- Ensure raw TCP/HTTP upstream requests copy original headers and skip X-Forwarded-* (which are added explicitly).
+- Add start_tls_ws_echo_backend test helper to start a TLS WebSocket echo backend for tests.
+- Add integration test test_terminate_and_reencrypt_websocket to verify WS upgrade through terminate-and-reencrypt TLS path.
+- Rename unused parameter upstream to _upstream in proxy_service functions to avoid warnings.
+
+## 2026-02-16 - 25.7.1 - fix(proxy)
+use TLS to backends for terminate-and-reencrypt routes
+
+- Set upstream.use_tls = true when a route's TLS mode is TerminateAndReencrypt so the proxy re-encrypts to backend servers.
+- Add start_tls_http_backend test helper and update integration tests to run TLS-enabled backend servers validating re-encryption behavior.
+- Make the selected upstream mutable to allow toggling the use_tls flag during request handling.
+
+## 2026-02-16 - 25.7.0 - feat(routes)
+add protocol-based route matching and ensure terminate-and-reencrypt routes HTTP through the full HTTP proxy; update docs and tests
+
+- Introduce a new 'protocol' match field for routes (supports 'http' and 'tcp') and preserve it through cloning/merging.
+- Add Rust integration test verifying terminate-and-reencrypt decrypts TLS and routes HTTP traffic via the HTTP proxy (per-request Host/path routing) instead of raw tunneling.
+- Add TypeScript unit tests covering protocol field validation, preservation, interaction with terminate-and-reencrypt, cloning, merging, and matching behavior.
+- Update README with a Protocol-Specific Routing section and clarify terminate-and-reencrypt behavior (HTTP routed via HTTP proxy; non-HTTP uses raw TLS-to-TLS tunnel).
+- Example config: include health check thresholds (unhealthyThreshold and healthyThreshold) in the sample healthCheck settings.
+
+## 2026-02-16 - 25.6.0 - feat(rustproxy)
+add protocol-based routing and backend TLS re-encryption support
+
+- Introduce optional route_match.protocol ("http" | "tcp") in Rust and TypeScript route types to allow protocol-restricted routing.
+- RouteManager: respect protocol field during matching and treat TLS connections without SNI as not matching domain-restricted routes (except wildcard-only routes).
+- HTTP proxy: add BackendStream abstraction to unify plain TCP and tokio-rustls TLS backend streams, and support connecting to upstreams over TLS (upstream.use_tls) with an InsecureBackendVerifier for internal/self-signed backends.
+- WebSocket and HTTP forwarding updated to use BackendStream so upstream TLS is handled transparently.
+- Passthrough listener: perform post-termination protocol detection for TerminateAndReencrypt; route HTTP flows into HttpProxyService and handle non-HTTP as TLS-to-TLS tunnel.
+- Add tests for protocol matching, TLS/no-SNI behavior, and other routing edge cases.
+- Add rustls and tokio-rustls dependencies (Cargo.toml/Cargo.lock updates).
+
+## 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
+
+- Adds loaded_certs: HashMap<String, TlsCertConfig> to RustProxy to store certificates loaded at runtime
+- Merge loaded_certs into tls_configs in rebuild and listener hot-swap paths so dynamically loaded certs are served immediately
+- Persist loaded certificates on loadCertificate so future rebuilds include them
+
+## 2026-02-15 - 25.3.1 - fix(plugins)
+remove unused dependencies and simplify plugin exports
+
+- Removed multiple dependencies from package.json to reduce dependency footprint: @push.rocks/lik, @push.rocks/smartacme, @push.rocks/smartdelay, @push.rocks/smartfile, @push.rocks/smartnetwork, @push.rocks/smartpromise, @push.rocks/smartrequest, @push.rocks/smartrx, @push.rocks/smartstring, @push.rocks/taskbuffer, @types/minimatch, @types/ws, pretty-ms, ws
+- ts/plugins.ts: stopped importing/exporting node:https and many push.rocks and third-party modules; plugins now only re-export core node modules (without https), tsclass, smartcrypto, smartlog (+ destination-local), smartrust, and minimatch
+- Intended effect: trim surface area and remove unused/optional integrations; patch-level change (no feature/API additions)
+
+## 2026-02-14 - 25.3.0 - feat(smart-proxy)
+add background concurrent certificate provisioning with per-domain timeouts and concurrency control
+
+- Add ISmartProxyOptions settings: certProvisionTimeout (ms) and certProvisionConcurrency (default 4)
+- Run certProvisionFunction as fire-and-forget background tasks (stores promise on start/route-update and awaited on stop)
+- Provision certificates in parallel with a concurrency limit using a new ConcurrencySemaphore utility
+- Introduce per-domain timeout handling (default 300000ms) via withTimeout and surface timeout errors as certificate-failed events
+- Refactor provisioning into provisionSingleDomain to isolate domain handling, ACME fallback preserved
+- Run provisioning outside route update mutex so route updates are not blocked by slow provisioning
+
+## 2026-02-14 - 25.2.2 - fix(smart-proxy)
+start metrics polling before certificate provisioning to avoid blocking metrics collection
+
+- Start metrics polling immediately after Rust engine startup so metrics are available without waiting for certificate provisioning.
+- Run certProvisionFunction after startup because ACME/DNS-01 provisioning can hang or be slow and must not block observability.
+- Code change in ts/proxies/smart-proxy/smart-proxy.ts: metricsAdapter.startPolling() moved to run before provisionCertificatesViaCallback().
+
+## 2026-02-14 - 25.2.1 - fix(smartproxy)
+no changes detected in git diff
+
+- The provided diff contains no file changes; no code or documentation updates to release.
+
+## 2026-02-14 - 25.2.0 - feat(metrics)
+add per-IP and HTTP-request metrics, propagate source IP through proxy paths, and expose new metrics to the TS adapter
+
+- Add per-IP tracking and IpMetrics in MetricsCollector (active/total connections, bytes, throughput).
+- Add HTTP request counters and tracking (total_http_requests, http_requests_per_sec, recent counters and tests).
+- Include throughput history (ThroughputSample serialization, retention and snapshotting) and expose history in snapshots.
+- Propagate source IP through HTTP and passthrough code paths: CountingBody.record_bytes and MetricsCollector methods now accept source_ip; connection_opened/closed calls include source IP.
+- Introduce ForwardMetricsCtx to carry metrics context (collector, route_id, source_ip) into passthrough forwarding routines; update ConnectionGuard to include source_ip.
+- TypeScript adapter (rust-metrics-adapter.ts) updated to return per-IP counts, top IPs, per-IP throughput, throughput history mapping, and HTTP request rates/total where available.
+- Numerous unit tests added for per-IP tracking, HTTP request tracking, throughput history and ThroughputTracker.history behavior.
+
 ## 2026-02-13 - 25.1.0 - feat(metrics)
 add real-time throughput sampling and byte-counting metrics

+### 🔀 Protocol-Specific Routing
+
+Restrict routes to specific application-layer protocols. When `protocol` is set, the Rust engine detects the protocol after connection (or after TLS termination) and only matches routes that accept that protocol:
+
+```typescript
+// HTTP-only route (rejects raw TCP connections)
+const httpOnlyRoute: IRouteConfig = {
+  name: 'http-api',
+  match: {
+    ports: 443,
+    domains: 'api.example.com',
+    protocol: 'http',   // Only match HTTP/1.1, HTTP/2, and WebSocket upgrades
+  },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'api-backend', port: 8080 }],
+    tls: { mode: 'terminate', certificate: 'auto' }
+  }
+};
+
+// Raw TCP route (rejects HTTP traffic)
+const tcpOnlyRoute: IRouteConfig = {
+  name: 'database-proxy',
+  match: {
+    ports: 5432,
+    protocol: 'tcp',    // Only match non-HTTP TCP streams
+  },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'db-server', port: 5432 }]
+  }
+};
+```
+
+> **Note:** Omitting `protocol` (the default) matches any protocol. For TLS routes, protocol detection happens *after* TLS termination — during the initial SNI-based route match, `protocol` is not yet known and the route is allowed to match. The protocol restriction is enforced after the proxy peeks at the decrypted data.
