 # Changelog
 
+## 2026-02-11 - 23.1.1 - fix(rust-proxy)
+increase rust proxy bridge maxPayloadSize to 100 MB and bump dependencies
+
+- Set maxPayloadSize to 100 * 1024 * 1024 (100 MB) in ts/proxies/smart-proxy/rust-proxy-bridge.ts to support large route configs
+- Bump devDependency @types/node from ^25.2.2 to ^25.2.3
+- Bump dependency @push.rocks/smartrust from ^1.1.1 to ^1.2.0
+
+## 2026-02-10 - 23.1.0 - feat(rust-bridge)
+integrate tsrust to build and locate cross-compiled Rust binaries; refactor rust-proxy bridge to use typed IPC and streamline process handling; add @push.rocks/smartrust and update build/dev dependencies
+
+- Add tsrust to the build script and include dist_rust candidates when locating the Rust binary (enables cross-compiled artifacts produced by tsrust).
+- Remove the old rust-binary-locator and refactor rust-proxy-bridge to use explicit, typed IPC command definitions and improved process spawn/cleanup logic.
+- Introduce @push.rocks/smartrust for type-safe JSON IPC and export it via plugins; update README with expanded metrics documentation and change initialDataTimeout default from 60s to 120s.
+- Add rust/.cargo/config.toml with aarch64 linker configuration to support cross-compilation for arm64.
+- Bump several devDependencies and runtime dependencies (e.g. @git.zone/tsbuild, @git.zone/tstest, @push.rocks/smartserve, @push.rocks/taskbuffer, ws, minimatch, etc.).
+- Update runtime message guiding local builds to use 'pnpm build' (tsrust) instead of direct cargo invocation.
+
+## 2026-02-09 - 23.0.0 - BREAKING CHANGE(proxies/nftables-proxy)
+remove nftables-proxy implementation, models, and utilities from the repository
+
+- Deleted nftables-proxy module files under ts/proxies/nftables-proxy (index, models, utils, command executor, validators, etc.)
+- Removed nftables-proxy exports from ts/index.ts and ts/proxies/index.ts
+- Updated smart-proxy types to drop dependency on nftables proxy models
+- Breaking change: any consumers importing nftables-proxy will no longer find those exports; update imports or install/use the extracted/alternative package if applicable
+
+## 2026-02-09 - 22.6.0 - feat(smart-proxy)
+add socket-handler relay, fast-path port-only forwarding, metrics and bridge improvements, and various TS/Rust integration fixes
+
+- Add Unix-domain socket relay for socket-handler routes so Rust can hand off matched connections to TypeScript handlers (metadata JSON + initial bytes, relay implementation in Rust and SocketHandlerServer in TS).
+- Implement fast-path port-only forwarding in the TCP accept/handler path to forward simple non-TLS, port-only routes immediately without peeking at client data (improves server-speaks-first protocol handling).
+- Use ArcSwap for route manager hot-reload visibility in accept loops and share socket_handler_relay via Arc<RwLock> so listeners see relay path updates immediately.
+- Enhance SNI/HTTP parsing: add extract_http_path and extract_http_host to aid domain/path matching from initial data.
+- Improve RustProxy shutdown/kill handling: remove listeners, reject pending requests, destroy stdio pipes and unref process to avoid leaking handles.
+- Enhance Rust <-> TS metrics bridge and adapter: add immediate poll(), map Rust JSON fields to IMetrics (per-route active/throughput/totals), and use safer polling/unref timers.
+- SocketHandlerServer enhancements: track active sockets, destroy on stop, pause/resume to prevent data loss, support async socketHandler callbacks and dynamic function-based target forwarding (resolve host/port functions and forward).
+- TypeScript smart-proxy lifecycle tweaks: only set bridge relay after Rust starts, guard unexpected-exit emission when intentionally stopping, stop polling and remove listeners on stop, add stopping flag.
+- Misc: README and API ergonomics updates (nft proxy option renames and config comments), various test updates to use stable http.request helper, adjust timeouts/metrics sampling and assertions, and multiple small bugfixes in listeners, timeouts and TLS typings. 
+
 ## 2026-02-09 - 22.5.0 - feat(rustproxy)
 introduce a Rust-powered proxy engine and workspace with core crates for proxy functionality, ACME/TLS support, passthrough and HTTP proxies, metrics, nftables integration, routing/security, management IPC, tests, and README updates
